I have just received my new pack and it doesnt. Also when I finish charging the pack it registers 8.22 volts on the 8 ball and 7.92 under 1A load is this normal? NO we no longer put the external jumper on the Peerless packs. So your battery is now in a normal configuration. Your battery when finished charging should be reading between abt. 8.3 and 8.4VDC. If you are using our charger ensure that you are allowing the battery to sit on the charger for about an hour after the Green LED goes out. This will ensure that the battery is getting fully topped off. If you are using someone elses charger this may be normal characteristic with that charger. 5b9d4180-b8f2-40d1-a53b-4ace0c6bc9bf2010-07-21T10:53:49-04:00 The most prevailent of the Gaint Scale Class. There are 3 classes of set up for this size of bird. Single Non-Redundant system. - 1-4800mAh+Reg, RX - 1-2400mAh+Reg. Ign. The single system is light simple and inexpensive. It does require that it's pilot is thorough on preflight checks, this set up allow for about 3 to 7 flights on a full charge. This is with a recharge voltage of 7.0 to 7.1. We recommend using "Heavy wire" and Deans or PowerPole connectors when running a 4800 RX pack in a 35% sized ship. Redundant system. - 2-2400mAh+regs. RX - 1-2400mAh+regs. Ign. The redundant system is like the single system above when it comes to flight time, about 3 to 7 flights on a full charge. The redundant system is a little more expensive due to the fact that it has a another regulator in the current path. The redundant system can be utilized with both single RX's and duel RX's. 4020cf6c-8567-46b3-8485-f755d70c00132010-08-22T15:59:18-04:00How adjust the out put voltage of Fromeco Regulator.7f8f38ce-7e00-4d8b-994e-8346840f61a22010-08-22T16:59:46-04:00In your 35% setup using two rx batteries and two regulators, are the two regulator outputs plugged directly into the rx?

These numbers are not absolute, numbers of flights per charge depend many different factors; time per flight, type of flying, and the end users Helicopter set up. This data is only a guide! .30 Class sized Helicopters - 2600 Relion or Peerless packs, 6-7 flights on a full charge, stopping when the pack reaches 7.2 volts under a 1amp load. - 5200 Relion or Peerless packs, 12-14 flights on a full charge, stopping when the pack reaches 7.2 volts under a 1amp load. .50 Class Sized Helicopters - 2600 Relion or Peerless packs, 5-6 flights on a full charge, stopping when the pack reaches 7.2 volts under a 1amp load. - 5200 Relion or Peerless packs, 11-13 flights on a full charge, stopping when the pack reaches 7.2 volts under a 1amp load. .90 Class Sized Helicopters Fromeco Recommends that 90 size heli's be only flown on 5200 packs due to amp load. - 2600 Relion or Peerless packs, 4-5 flights on a full charge, stopping when the pack reaches 7.2 volts under a 1amp load. - 5200 Relion or Peerless packs, 10-12 flights on a full charge, stopping when the pack reaches 7.2 volts under a 1amp load. ed09d05c-5a82-4f0f-aaef-e5e0bc98c2142010-08-22T15:59:18-04:00Can I test an 11.1v Li Po battery with my 8 ball load checker.19c0c13a-04e1-4341-b883-e8d7c7455ff32010-08-22T15:59:18-04:00 I have a couple older Fromeco Regulators, and I was wondering if they can handle the voltage input that a three cell pack woudl have?

I love your batteries and charger by the way.f2b26736-0ddd-4922-ba2e-adc4e97a72452010-08-22T15:59:18-04:00I just recently purchase 2-2400 mha lith ion batteries, Relions, I ordered them with the Deans connector to match my Arizona reg. since there is no seperate plug for charging the batteries outside of the heli, is it ok to charge them while in the heli thru the charge plug(black).19a99243-88a2-46da-bb62-a3db2af3f1232010-07-21T10:53:49-04:00 Lithium ion batteries do not require any forming protocols. We tend to ask a few questions when a load checkers is showing a normal fully loaded voltage but an unusually depressed loaded voltage. - Is the battery installed in a system? - Where is the battery in regards to the charging lug, in other words are you tapped directly off the battery or are you going through a switch? - How long is the lead from the switch to the battery? - How long is the lead on your load checker? - What is the make/model of load checker? - Has the load checker been confirmed to be functional (i.e., different checker => same results)? These are all things that can give a significant amount of voltage loss in a system. This is due to resistance or "line loss". We do like to work with our customers directly with this sort of issue, because damaged cells (e.g., stored in high heat) also exhibit more of a drop than normal under load. This is one reason why routine load checking is so important; given a properly functioning load checker they will give early notice of any problems in the electrical system. 7885f9a0-9748-4bd9-97f3-73a652762e102010-07-21T10:53:49-04:00 After reading some of the questions in the knowledge base Im somewhat confussed at the discharge limit of a Li-ion battery. Some indicate to recharge at no less then 7V and some posts indicate that cycling can be performed to 6V. I have been following the rule to recharge prior to battery reaching 7V. How low can the battery be discharded to and is the rule of recharging at 7V a general safty margin. - Discharging to 7.0VDC This is for normal use and should be used 99% of the time. 7.0 volts under a 1amp load is what Fromeco considers out of gas under conditions where loads are unknow and flight times may vary, (every day flying). This is the limit for discharging under flight conditions. It is very important to not confuse this with doing a very controlled discharge test. Yes the 7.0VDC is slightly conservative, however with Lithium XXX chemistries the discharge curves for the end of charge are very steep, (read little to no warning when pack is empty). It is very important to respect this under flight conditions. 7.0VDC @ 1amp for 7 to 10 seconds. - Discharging to 6.0VDC This is for doing testing~Fromeco recommends this should only be done by folks that have experience with discharging batteries. Why can you discharge a Lithium Ion pack to 6.0VDC for testing and not in flying conditions????? Discharge tests are done under controlled conditions, the rate of discharge is controlled, the Voltage that the packs is being discharged too is known. There is not RC equipment at stake. Caution must be used when doing discharge tests. 1.) The pack should not be discharged lower than 6.0VDC, there is no usable data gained from going any lower. 2.) This should only be used to check the Capacity of a Battery Pack. Do not do these tests to test the Maximum out put of these batteries, we have done these tests under contolled conditions, we can tell you what this is. 3.) The rate of discharge should be less than 500mAh to ensure accurate readings. 4.) Tests should only be done when absolutely required. 5.) The pack needs to put on charge as soon as the test is completed!!! <---VERY IMPORTANT d12c865d-1f39-4f9e-b3ab-6325e9827e822010-07-21T10:53:49-04:00 Question i seem to be having a problem i beleive. when i power up 1 of the 2 switches in my plane the other on comes on as well no matter that its turned off. both of them do this whats the deal?? could this be correct for the power to back feed to another switch??? it does not do this on any of my wolverines or badgers. iam using 2 wolverines, 3 badgers and 2 kodiaks total in my fleet and only the kodiaks do this... turn one on and the other one lights up NOT GOOD. little help please Answer You have no worries. There is not current back flow, nor will you counter be incorrect. What you are seeing is just voltage lighting up the back end of the Kodiak switch. An easier way to think of this is using a water analogy. If this were a pipe being fed from the other switch, you would have water there, things would be wet, but it would not be going anywhere, flow meter would read zero, if it was clear plastic pipe you would be able to see the water, (lights). On the Diode, yes, uhh no. Using the water analogy again. Diode like a check valve in water and would cause a flow restriction. Since the Kodiak was designed with A123 and is capable of 30amp currents, a flow restriction was not an option, + it is added un-needed cost. f12834f6-3946-45ae-b604-37ee4b6a5abe2010-07-21T10:53:49-04:00 What voltages should I be seeing when the pack is fresh off the charger? The charger terminates @ 8.4v and the pack quickly stabilizes to 8.25v. What kind of voltages are expected w/ 0.5A and 1.0A loads? The Voltage you are seeing off a Fresh charge is a little low, however this really depends on the charger, how old your batteries are, and how you have treated them since you put them into service. - If it is our charger, please remember the chargers light goes out when the battery has reached a state of about 92% capacity. With our charger it is a good idea to rock the "rocker switch" one more time after the green light goes out. Let the charger run for another hour, if you have the time. This will give you the fullest charge; your readings will be about 8.32 to 8.35volts for both a 2400 and 4800 Relion/Peerless. - Our charger ("Reliacharger") terminates at 100mA for the 2A setting, and 25mA at the 1/2A setting. Use the 1/2A setting to "top off" a charge, if you desire to top off the battery as far as it will go. - Not all chargers terminate alike. The basic principles are the same but there can be subtle differences between charger brands as far as termination. When a New battery is pulled off a charger that is indicating full charge, and the battery does a very sudden slide down to 8.25volts. This is a good indication that the charger terminating at 8.4V while still putting in significant current (e.g., 100-200mA). This is not a bad thing, this just means when you pull that battery off the charger there will be a little slide in VDC. Another thing to keep in mind is, putting amperage, or current into a battery drives up the voltage, if you have a small current going into the battery when the charger says 8.4volts and you take this away, the VDC will slide just a slight amount. What Voltages are expected at a 1 amp load. (We only recommend a 1amp load) The figures below can be swayed by temperature, load duration, and instrument used to take readings. 8.3VDC was used as a starting point, the check duration is approx. 7 seconds. Batteries are "New". - Relion 2400 at full capacity 7.9X under a 1 amp load - Relion 4800 at full capacity 8.1X under a 1 amp load - Peerless 2400 at full capacity 8.0X under a 1 amp load - Peerless 4800 at full capacity 8.15 under a 1 amp load 4ff42642-7dab-412a-9854-74bed0d3cc122010-08-22T15:59:18-04:00 How to properly power up your Cubea7f34ab9-e86f-45d6-a6da-e5b79056de0a2010-07-21T10:53:49-04:00 Important Ion Cube Power Supply Faqs, Please read if you are having an issues with your Ion Cube, related to rate of charge or blinking light codes. fac1dd74-47bf-4f25-ae00-4cfdb4ca75cc2010-07-21T10:53:49-04:00Can I use both A123, and Lithium Ion Charger channels in my Ion Cube?b28d1a1a-2331-411c-a938-4689fc3196992010-07-21T10:53:49-04:00Does the Ion Cube have balancing circuit?6452510a-3555-4a86-a5b2-a2be750dcdb82010-08-19T12:26:12-04:00What is the Difference between A123's and LiFePO4 cells?1c25bbbf-2355-46b4-91b8-a65387bca9042010-08-19T12:18:30-04:00Q&A Are Litihium Ion as Prone to Fires as Lithium Polymers?cfe60777-b710-4804-a0c4-3641ab7b50db2010-08-19T12:18:30-04:00Hi, considering swapping out my LiPos for Li Ione0afc61c-7efd-45dc-9812-08f97d2b08dd2010-08-22T15:59:18-04:00 I have a triton charger.

The Super Regulated Reliaswitch is an upgraded "The Regulator", so that the regulator pass element also does double duty as a solid state switch. The upgrade includes: - an extra JR plug for the switch harness to plug into - a pin & flag type switch harness - another JR plug that allows checking the battery The Super Regulated Reliaswitch uses a pin & flag system in a failsafe configuration...the pin jack mounts into the side of the aircraft, and the pin is inserted into it to shut the Reliaswitch down. The pin looks a bit like a miniature sardine can key, with a little red flag on it that reads "REMOVE BEFORE FLIGHT". The two major advantages of the Reliaswitch are: - when you pull out the pin, the system is on, and you are holding the only moving part in your hand! - there is no need for a mechanical switch, i.e., you are able to omit that from your power system. Important note: The Super Regulated Reliaswitch does draw a small amount of current even when it is turned off (2 to 3 milliamps). This is not noticeable for the long weekend fly-in, but you will want to disconnect the batteries from the Super Regulated Reliaswitch to prevent the battery from slowly draining when in storage over the course of several weeks. c494eeec-505b-41df-bd30-1e1aa03969112010-07-21T10:54:14-04:00 Using the Duralite charger with our batteries will void your warranty with Fromeco. This is because the Duralite charger has a rather wide termination voltage range from unit to unit, in our experience. This can result in overcharging batteries that do not have their particular in-pack circuitry (i.e., Fromeco and others). Charging our packs with this charger can lead to cell and pack damage 6b1d6271-4a41-4681-9729-4db80bff04932010-07-21T10:54:14-04:00 The Triton charger checks the pack before starting the charge. Since the internal impedance of lithium ion cylindrical cells (Fromeco, et al) is substantially higher than LiPos, the charger may charge at a reduced rate. For instance, you might set up the triton to charge at 2A, but find that it is only charging at 600mA or so. The workaround is to use short charging leads, and as direct a connection as possible to the battery being charged. The idea is to reduce the amount of resistance in the wiring and connectors as far as possible. For instance, replacing 18" 24 ga. leads with 6" 20 ga. leads, and/or plugging directly into the battery instead of through a charge-port switch, will usually allow a reasonable charging rate. 0d5cf53b-35a9-4f49-8402-073862e8fedc2010-07-21T10:54:14-04:00 We have many customers that call and ask us this question. The answer is Yes. We do have many customers that use this charger with great success. Your setting should be: - Voltage should be set to 7.4VDC - Amperage should be set at or below 2 amps or 2000mAh 52c029ab-07b7-4dad-918c-79f5b6b04fa82010-07-21T10:54:14-04:00 28% Aircraft are both hard and easy to set up. These planes are basically an inbetween size for just about everything including batteries. Many who fly this size of Aircraft can speak first hand at how imortant and critial weight is to this size of plane. - 1-4800mAh+Reg. for RX, and 1-2400+Reg. for Ign. This set up provides ample capacity and flight time per charge. In most cases the charge will out last it's pilot in a day of flying. This is the set up that we recommend on this size of Aircraft. - 1-2400mAhPeerless+Reg. for RX, and 1-2400mAh+Reg. for Ing. This set up requires thorough preflight checks, and load checks before each flight. e5462983-30d8-4dbc-8eb6-ddc536b9d14c2010-07-21T10:54:14-04:00 830be4a9-5576-4d50-a770-adf8d8ce25ca2010-07-21T10:54:14-04:00 35ac806e-c736-4deb-87e6-121bb00202222010-07-21T10:54:14-04:00 By digital charger we are assuming you mean our charger or Reliacharger. Yes the charger will time out on a 4800 most of the time, especially if the 4800 is really depleted. What we recommend you do is, put your 4800 on charge after an hour of charging come back to the Reliacharger and Rock the Rockerswitch, this will reset the timer. You do not have to pull the batteries off the charger to do this, it can be done while a charge is taking place. The switch controls the both the Rate of charge and the 3 hour safety timer. On the 3S 2500 pack, the Super Reliacharger only charges 2S or 7.4volts, so yes you will have some problems here with not getting even close to a full charge. 057d264c-b1ad-4490-b31c-21965d1c4b3f2010-07-21T10:54:14-04:00 I have a triton charger.

Use the 2s/7.4v lithium setting, and set the charge rate between .5 and .8C for optimal battery life (they can be charged at a max rate of 1C). Be aware that the Triton does a cell impedance check (and will prorate the charge rate accordingly, based on LiPo, not Li-ion cylindrical characteristics), so please use relatively short, thick charge leads for best results. 72c10029-ae3f-4dc9-9aea-dab8b16cc52d2010-07-21T10:54:14-04:00 I have a triton charger.

Would there be an advantage in using the pin and flag system over the slider switch? What size wiring does it come with if one choses not to upgrade tp 16 G.? Nominal current draw on an "off" badger switch is 21uA, which is comparable in magnitude with the self-discharge rate of the pack (1/2mA-h per day). It can be used in the same way as a mechanical switch, because this draw is so minimal. The pin-and-flag or slider switch are used to pass a control signal to the solid state element, not to actually pass current. The slider is easy to turn on and off when the switch is mounted on something that's vibrating; the advantage of the pin is that you're holding the only moving part in your hand when the switch is turned on. Wiring is 16ga (14ga for "custom" wiring lengths) for the heavy stuff, and 22ga, 6" in and out when we set up a badger with universal (JR) type connectors.13bbee33-01b5-4327-8a23-5b88e3d2158a2010-07-21T10:54:14-04:00 If I charge my 2400 Relions using the 2A setting, after the green light goes out can I set the toggle switch to the 1/2A setting and let it go until the green light goes out? I want to top off the packs after the 2A charge is done. That's right. The charger's green light goes out when current reaches 100mA on the 2A setting, and 25mA on the 1/2A setting (C/20). Selecting "1/2A" to do a topping charge works well. The charger does continue to charge at a low rate for about 45 minutes after the green light goes out, as well. There's no indication, though. The green light going out is intended mainly to be a "full-enough-to-fly" indicator, and represents about 92% of charge. Please be aware that the charger also has a timer; charger will turn off after 3 hours whether the battery is full or not (safety feature). d8cd0022-0e69-43d1-aaf1-93088c1b4dbb2010-07-21T10:54:14-04:00 If I charge my 2400 Relions using the 2A setting, after the green light goes out can I set the toggle switch to the 1/2A setting and let it go until the green light goes out?

You are correct in all your statements: 1C max charge rate, .5 to .8C charge rate for longest life & reasonable charge rate. The cell manufacturers specify .5C charge rate for cycle testing, incidentally. There isn't a minimum allowable current, but you still must follow the CC/CV algorithm, i.e., the charger should reduce current to maintain termination and must shut off the charge when the pack voltage is 8.4 volts or less, and when the input current is 25mA or more (no problem with the Apache). 70976445-d98e-4884-9485-0510c84f23762010-07-21T10:54:14-04:00 ...I did not find the recommended charging current for the 2400 batt.

When I fully charge them, one of them reads 7.8v and the other 8.1v. Is the one reading 7.8v is still good to use? They are about 2 years old. Fromeco recommends replacement of batteries after 2 years of service. This is a recommendation that comes from the OEM of the cells. Packs that are properly cared for through out their service life can and many times do last longer than 3 years. Once the 2 year mark is reached on a pack, Fromeco recommends that packs are monitored more closely for degridation of capacity. This can be done by doing a capacity check. (Please refer to Knowledge Base Article on Battery Care). Safety is First, if you think you have a pack that is past its service life or you know you do. Do some testing on the pack make sure it is fit to fly. When you receive you new battery packs always remember to write down the date you put them into service somewhere on the pack. 328deaa4-c52f-4cae-85c8-fd269d65b6c32010-07-21T10:54:14-04:00 420ba29a-326b-433f-b36c-4da2fd90f1f02010-07-21T10:54:14-04:00 734bcb9c-9b62-4353-8625-2b0788ca73282010-07-21T10:54:14-04:00 I recently finished building an Aviation Models 33% extra and used 3 of your Peereless 2400 battery packs. My question is about the volatility of these batteries. It seams a little difficult to remove the cowl to get to the ignition battery for charging. Is this necessary or can the battery be charged in the plane. I dont want to risk the plane, so if this is not possible I will have to go to a Nicad or NiMH pack for ease and safety. Thank you for your help. Fromeco chooses to recommend the conservative policy of removing batteries from the aircraft for charging, and keeping a half an eye on them during the charge cycle (please see the "instructions" section of our web page for full set of cautions and disclaimer). We do acknowledge that this has rather more to do with tort than engineering...with a properly functioning charger and following standard charging parameters, the actual chances of an event are negligible. Comment response: The Badger switch is not just for our batteries, it is a suitable switch for NiMH and NiCD as well. What Mike is trying to say in the comments above is, we understand that there are quite a few pilots out there charging their batteries in their planes. For Liability reasons Fromeco has to error on the side of safety. The chances of something happening with a proper charger, are slim and next to none, (for Lithium Ion only, not Lithium Polymer.) Ultimately the decision is yours on how you choose to charge your systems. 69fe1041-9cde-49fe-9b64-8aad9ecbcfbd2010-07-21T10:54:14-04:00 I recently finished building an Aviation Models 33% extra and used 3 of your Peereless 2400 battery packs.

Will this work with Fromeco batteries? Fromeco has not done testing on this charger with our batteries. We have reveiwed the specifications. Yes according to the specification this charger will work fine for our batteries. Settings Voltage = 7.4VDC Amperage = 2000mAh or below Ensure you are in the Lithium Ion or Lithium Polymer setting NOTE: The "Pro Peak Prodigy" instruction manual is linked to this article below. 843a14e0-eece-4886-9d1f-4010d20b476b2010-07-21T10:54:14-04:00 Are the two leads on my new Peerless pack (JR lead w/20ga and Deans w/ 14ga) both connected via the safety/balance circuitry? In other words, can i charge/check the battery safely via the JR plug even though I plan to use the deans for powering the heli? Our Peerless batteries' circuitry is designed to be completely transparent to normal use, and both sets of wires do go through the circuit. 395a02dd-9e9b-427f-b67e-4d03187e63ed2010-07-21T10:54:14-04:00 Are the two leads on my new Peerless pack (JR lead w/20ga and Deans w/ 14ga) both connected via the safety/balance circuitry?

Can I use a Schulze ISL 6-330d (software ver. 8) to charge Fromeco batteries? http://www.schulze-elektronik-gmbh.de/isl6-e.htm Yes you can use this charger to charge Fromeco Batteries...............However, with the software version that was specified the charger will not charge Fromeco Batteries to their full capacity. The Tech. notes on the software version state that the charge regime is a 3.6 volt per cell regime. Fromeco Cells (as with most new cells on the market) are 3.7 volt cells. This means that the cells will not reach their full capacity. It will not hurt the batteries what so ever to use this charger. e5599a66-a08e-4c2e-a30e-df1c31ef36122010-07-21T10:54:14-04:00 Kurt or Mike, Ive been using your Relions in my 35% IMAC plane for a couple of years now, truly sold on their reliability. Im going to get back into pattern this year with an electric plane, and would like to use your batteries for the RX and SXs. Im use to the Relions with the single output wire that attaches to the on-board switch, etc. On the Peerless batteries, it appears the traditional lead and plug would be to charge? The heavier 14 awg wires would go to the switch and regulator? The Peerless Battery do have to out put leads, both leads are discharge leads and or Charge Leads, there is no Difference between the two. We put both leads on the battery for the convenience of our pilots. Many like to use the Heavy wire for Emcotec and PowerBox type units, with the Extra JR lead these customers can also charge their batteries with out unplugging them from their on board systems. 071f7c31-157a-42f6-85ba-c67752eeaa5e2010-07-21T10:54:14-04:00 I have been given some advice by a friend at my local field as to what an ideal battery set up would be for my raptor 50 heli (as detailed below). Before I purchase these items I would like to ask how many flights I could expect from a single charge and also more importantly is my charger (Ripmax Pro-Peak prodigy 2 (part no. 0-IP2801)) suitable for this set up and would using this charger invalidate any warranty? Yes you will be able to use the charger, Knowledge Base Article is below on that topic. Flights on a 50 Raptor, also added a Knowledge Base Article below on flight times for different size Helicopters. a38ed0e9-82bb-4fdc-b990-21f902eb95e72010-07-21T10:54:14-04:00 7dda4a22-1276-45fd-931b-b5151fb9b4512010-07-21T10:54:14-04:00 Do I need to wrap the batteries with foam??? Thanks No, they don't need to wrapped with Foam, we do suggest that you put them on a Foam Bed, and then properly secure them to protect them from Vibration. NOTE: Wrapping them in Foam will not hurt them either, if this is a standard practice for your set ups and you feel most comfortable wrapping your batteries in foam then go for it. Attached below is a Knowledge Base Article about the installation of Fromeco Regulators, if you have questions about those please read this article as our suggestions for Regulators are quite different than batteries. 60c0baa0-8928-4b7e-8186-dcbb7b4712862010-07-21T10:54:14-04:00 Just ordered a Aerotech 28% Yak 54. Wingspan is 84" and will power the plane wit ha DA 50 Engine. Will also have 5 Hitec 35955S Servos for the control surfaces producing 333 oz torque at 6 v. Will also have two standard digital servos for choke & throttle. Would like a full day of flight without having to recharge. Would appreciate your suggestion for Rx batteries and iginition battery and regulators(s) if required. I use JR radio. For a 28% Yak the 4800 Peerless or Relion for RX, and 2400 Peerless or Relion for Ign. is the perfect set up. This will allow for a full day of flying in most cases. A full day of flying would be considered at the least 8 flights at 10 minutes a piece. If a Redundant system is needed then 2 2400's in place of the 4800 will also work as well. Also remember when flying hard like this it is very important to manage your batteries correctly, proper load checking between each flight.

Im using it to charge the 2400 & 4800 Relion Batterys. We do not have any experience with this charger in use, however its specifications show that it is compatible with our batteries. It does appear that it will try to charge a Lithium Ion at the 3.6 per cell or 7.2VDC in series rate, if you find this to be true use the Lithium Polymer setting of 3.7 per cell or 7.4VDC in series. Our packs are 7.4VDC packs.

The Pin and Flag Switch is a Device that Fromeco developed 5 Years ago and has been incorporating in to products ever since. How Does it Work? - Plugging in the Pin and Flag turns OFF. - Unplugging the Pin and Flag turns ON. What Fromeco Devices can use the Pin and Flag? - Arizona Regulators - Super Regulated Reliaswitches (SRR) - Badger Switch Pin Flag Version What are the Benifits of using a Pin and Flag system. - Allows for a direct connection of battery to that device (Arizona, SRR). - Fail Safe operation, the Pin and Flag holds the device in the OFF state electrically, if the Pin is removed the device is in its normal state ON. - The only moving part of the switch is removed once the Pin is pulled. - Less prone to Vibration induced failure. - Light weight. - Loss less connection to the battery, (no mechanical switch in between the battery and device) only one set of connectors between the battery and device vs. two with a standard mechanical switch. Mechanical switches will have some loss accross there wipper arms or contacts. Does this mean my Arizona/SRR/Badger Pin Flag is always using battery when plugged in? Yes it does. - Arizona Regulators use about 21uA or 1/2mA-h per 24hr. period, current drain is less than a Lithium Ion battery self discharges sitting on the bench. - Badger Switch Pin Flag use about 21uA or 1/2mA-h per 24hr. period, current drain is less than a Lithium Ion battery self discharges sitting on the bench. - SRR use about 3mA this switch should be unplugged when not being used for extened periods of time. If systems are not going to be used for more than 2 weeks we recommend unplugging them. Is the Pin and Flag interchangable with a standard off the shelf switch? NO. - A standard switch can still be used with Arizona/SRR/Badger Pin Flag devices. However they must be plugged in series with these devices, Battery***Mechanical Switch***Arizona/SRR. - Standard switches will NOT work if plugged into the Pin Flag connection lead provided with Arizona and SRR. - Will a Badger switch work in place of the Pin Flag if connected to the designated lead for Pin and Flag? NO. Mounting the Pin Flag Recepticle - Do NOT mount to metal unless the metal is mounted to a non conductive material, (plastic or wood). - Do NOT mount to Carbon Fiber unless the Carbon Fiber is insulated with a non conductive material. Below is an attatchment photo of a Pin Flag installed on a Helicopter. c9c9af82-c7bc-4422-ad0d-29ebbc9608db2010-07-21T10:54:14-04:00 e639b89a-0663-417c-a3da-78fe3338a3d12010-07-21T10:54:14-04:00 Hi I was considering aquiring some peerless batteries but since I have a charger that automatically chooses 3.6V per cell for Li-ons and 3.7V for Lipos, I wonder if it would be ok for me to charge your batteries as Lipos on my charger (its a ELV Expert 8500-2 see http://www.elv-downloads.de/downloads/elvcom/alc8500.htm ). Thank you very much in advance. Many chargers have Lithium Ion and Lithium Polymer settings. Some of these chargers have a 3.6volt setting for Lithium Ion and a 3.7volt setting for Lithium Polymer, or two cells it would be 7.2volt and 7.4volt. The 3.6volt is a legacy setting for the older technology Lithium Ion cells. This difference in voltage has to do with the Raw Material that make up the individual cells. Fromeco Batteries, both the Peerless line and the Relion line use the cells that are of the 3.7volt variety or 7.4volts for a two cell pack. What setting to use with Fromeco batteries? If all you have for Lithium Ion cells is the 3.6V setting, and the Polymer has a 3.7V setting. Use the Polymer setting. Will using the Polymer setting hurt my batteries? No, not at all. The Lithium Ion charge regime, wether it be Polymer or Ion are exactly the same. Will my Fromeco batteries be fully charged if I use the 3.6volt setting? No, the Lithium charge regime relies on the termination voltage to determine when the battery is fully charged. If you have a 3.7 volt cell that you are only charging to 3.6 volts there is capacity that is not being utilized.

I see that it has built-in balancing circuitry. Does this mean I do not need a separate cell balancer when I am charging them, or during use? In other words, I could hook this directly up to my Accucycle Elite and not have to worry about unbalanced charging? How much flight time can I expect from the 2400mah peerless running 3 standard JR digital servos (DS821), 1 submicro digital servo (DS285) and 1 JR 7channel synthesized PCM receiver, in my CG Superchipmunk? In general, small packs such as a 2s2p Li-ion are best balanced by simply using high quality cells of recent manufacture and from the same lot number. We do this for both Relion and Peerless packs. Accucycle Elite works well for both of our battery lines, and you won't have to worry about unbalanced charging. Guessing at flight times would be a bit chancy on our part, because it is highly dependant upon type and size of airframe, as well as specific setup detail (including servo types) and style of flying. A Carl Goldberg Super Chipmunk should get over 5 flights on a single 2400 with the above stated system, in good working order. 7873aefa-81cc-4c4c-8a95-b9fe979faea52010-07-21T10:54:14-04:00 Im interested in your 2400mah peerless Li Ion pack.

I used a 5 amp discharge load and set the test shut-off voltage at 6.0 volts to obtain my representative discharge curve. Obviously, this is more of an information input rather than a question, however I would inquire as to whether you would recommend doing this on new packs. It if fine to use the CBA to do load testing on new packs. We would recommend that you use a much lower discharge current to get an accurate display of capacity of the pack that you are testing. Most cell manufactures recommend a discharge current of C/5 or about 500mAh. We do recommend you keep it under a 1amp load. This will give you a good capacity graph that will be useful when the batteries are retested after some use. The 6.0VDC shut off is a good one, going any lower doesn't really give you any useful data. Please follow the link below. We outline the dishcharge specs there. 219001c7-8f67-4dbc-9f03-56c1ca185ff02010-07-21T10:54:14-04:00 I ordered an 8 Ball load tester, and I understand that it will indicate when you are ok to fly and when you should charge. How can the interim status (1/3, 1/2, 3/4 capacity), of the battery be determined ?, by the voltage level of the pack ? Yes, the best way to accomplish this is document your flights per charge. Knowing that you need to recharge at 7.0VDC, track the number of flights you get in between your full charge Voltage and the 7.0VDC voltage. 5a09a453-1c65-48c3-b09b-726c137d23652010-07-21T10:54:14-04:00 Can I use my Duralite charger with Fromeco batteries? Check KB article added below. 4822ffab-0079-49d3-b01e-54fcb18110d42010-07-21T10:54:14-04:00 6b3dcff6-9674-4842-b6c8-0ad04c17509b2010-07-21T10:54:14-04:00 What is the differtence between the futaba type connector and the thick wires on your batteries. Is this for ballancing the packs or is it just another type of connector? All Fromeco Batteries are sold with a JR connection as a standard option. The reason we use JR is, it is compatible with both the JR and Futaba Radio systems, which are the majority of the market by far. Fromeco's Peerless line does come with a JR and a set of heavy 16awg wires. The JR plug is not just for charging, it can be used to out put, charge, or as a voltage monitor. Many think it is just for charging and the balanceing circuit but this is not true. The 16awg wire and JR lead are interchange able as far as there purpose on the pack.. 7be790b2-6ed0-47ac-b418-05d020e9f35c2010-07-21T10:54:14-04:00 I have the Arizona Regulator and 2400 Peerless pack. If Im flying towards the end of the charge, how does the pack react? Will it shutdown in flight? There should be no difference between the end or charge and the beginning. The Pack will not shut down at end of charge. Lithium XX chemistry batteries do have a very nasty habbit that does exist at the end of charge. If you look at Graphs of Lithium Ion/Polymer batteries discharge curves you will notice that the VDC drops very, very dramatically at the end of charge. We call this the cliff. Under load this drop off is litterally a matter of seconds. Other chemistry batteries such as NiCad and NiMH your controls will get mushy and things may not feel right. With a Lithium it is likely you will lose everything all at once with no warning. If you are operating at the end of charge and have not done a proper load check there is a good chance that bad things could happen. Load checking is absolutely critical with any Lithium chemistry battery especially if you are using these systems on your RX. Good Load Checking - Ensure you load checker is applying a 1amp load or higher. - .5AMP IS NOT GOOD ENOUGH - Apply load to battery for 7 to 10 seconds. (Critical) - Apply load until voltage readings stabilize. - Make sure you Load checker is in good working order. If the load applied is not high enough or long enough, your batteries will most likely indicate that they are still with in proper operating parameters. 5d8c6780-89a3-4d6a-b58c-92d839e46d502010-07-21T10:54:14-04:00 I currently own the AstroFlight Lithium Model 109 charger with the most current firmware chip.

OR is there a multi-output charger that will charge both types of cells? Yes Lipoly packs can be charged on our chargers. The Reliacharger will only charge 2S or 2cell packs, as long as that is taken into consideration, then yes go for it. 40bc4f16-11ce-40f6-a6ad-7e405b518a942010-07-21T10:54:14-04:00 Two questions - I have 2400 and 4800 LiIon batt: 1. What is the life expectancy of the batt in number of charge cycles? 2. Should the batt be nearly depleted before charging, ie, does charging partially used batts harm them?? - Life expectancy is abt. 2 to 3 years or 300 to 500 charge cycles. The really depends on how the batteries are cared for. Battery care covers a wide range of things, temperatures, charging, discharging, storage. - No, charging can take place at any point in the discharge cycle, it will not hurt them to charge them in the middle of the discharge cycle. e1f97e76-997a-4758-b550-c45bad8726952010-07-21T10:54:14-04:00 e3052f58-c036-4418-a8fa-bff3caa4b8722010-07-21T10:54:14-04:00 On the Peerless batteries there is a jumper. There was no directions sent with the batteries that let you know what the jupmer is for. Can you please let me know. Peerless Batteries are no longer sold with the Safe Ship Jumpers installed. We recommend that the Jumper be removed and thrown away, if this is done your battery will operate as the Peerless batteries that are currently being sold. 9902715d-7edf-4f63-8836-a045ef0450722010-07-21T10:54:14-04:00 9419be95-34dc-4131-98bd-06b31ca5853e2010-07-21T10:54:14-04:00 Will a powerflite charger work with Fromeco batteries?

I have just bought an 8 ball for my 4800 peerless setup. Do I need to make up a deans lead to adapt to the 8 ball as I have the deans upgrade on the peerless battery or do I simply plug it into the charging lead which is a direct fit. I am sorry if this is the simple answer but its not in the instructions and I am not sure if it will affect any of the cell balancing circuitry in the peerless line of batteries. The instructions say relions or li polys and just to plug it in. The JR Plug on the peerless and the Heavy wire go to the same place on the board. The JR connector has nothing to do with the Circuitry, so you can use it no problem. f82ed5b9-adc6-4363-a5e1-7aaada798fca2010-07-21T10:54:14-04:00 My Triton charger keeps giving me input voltage errors, even though the voltage doesnt above or below the stated voltages.

It says it can charge Li-on batteries. Can I use this charger with your batteries? Yas Sir! 9dd88892-825f-4818-8459-8d687f09d8122010-07-21T10:54:14-04:00 I have just purchased the 4800 Peerless and have a Swallow Advance charger - When I set the charger for Li-Ion it is set At 7.2 volts. on Li-Po the charger is set at 7.4 volts. If I charge the batteries on the Li-Po setting (7.4) will this harm the batteries?? The Swallow Advance is capable of charging our Li-ions. You may use the Li-po setting of 7.4V (2s or 2-series), because the charging curve for the Li-ions we sell is the same. For longest life, charge at a .5C to .8C rate. The 7.2V for the Li-ions comes from an earlier cell construction, which is no longer common. 898c6ae6-0307-44e5-9e88-302d0eb7e2be2010-07-21T10:54:14-04:00 I have just purchased the 4800 Peerless and have a Swallow Advance charger - When I set the charger for Li-Ion it is set At 7.2 volts. on Li-Po the charger is set at 7.4 volts.

WITH AN ELITE BATTERY CHARGER. Your Elite charger needs to be set on a Lithium Ion or Lithium Polymer setting, the Voltage needs to be set at 7.4VDC, the amperage should be set no higher than 2.4 amps. A good setting for amperage is 2.0amps. f1e818f4-e78d-4ac3-9cdb-5ed7c9cd010f2010-07-21T10:54:14-04:00 a422dc4a-da30-40dd-8fe6-0912c61da3b02010-07-21T10:54:14-04:00 I have dual batteries into dual regulators into a single receiver. Can I simply charge both batteries with 2 channels of my relia-charger? would I need to disconnect my batteries to do so? Yes you can as long as you have a proper set up. Please note it you don't have your system set up this way you should get it in this format. - Battery - Switch - Regulator - Receiver As long as you system is put together in this order, charging dual batteries into one receiver will be not problem. If you have 2 Realiswitches you can also charge using 2 channels of the charger. The Regulators, in the off state will prevent reverse current flow. 47efd600-5278-4ca9-a122-baf7e7d7992c2010-07-21T10:54:14-04:00 can i charge through either lead or do i have to charge through the blue lead on my battery?

I have a question about the 4 cell 4800 mAh redundant LiIon packs. During operation is current drawn by the two sub-packs (2x2400mAh) or just from one and when voltage falls under a certain point the other sub-pack is activated? How does this thing work? Do the batteries run in paraller or theres some kind of logic behind? Does the pack incorporate any special circuitry? No, a 4800mah pack is built in Series Parallel, or 2S2P. Power is drawn from the Paralleled 2400mah packs equally, (basically) if the packs is discharged at an excessive rate they can experience un-equal discharge due to individual cell resistances. Note these types of loads will not be experienced in a properly set up Aircraft. Our Peerless line of packs do have circuits, these circuits have nothing to do with the Discharge of the pack. Fromeco really tries to shy away from the Statement that the 4800mah packs are redundant. We know that other companies use the (Redundant Like) configuration of the 4800mah pack as a benifit. Reality is the pack is not truely redundant and should not be called that. 3e6eec3e-30d4-4d0c-ae9b-3ecc3baa5ca72010-07-21T10:54:14-04:00 I have a 4800 peerless pack that i want to store during the winter. I found info that it should be discharged to about 7.4-7.7 Volts. Is that with 1 amp load on it? No this would be a static State of charge. acab4d1b-8b63-4f46-929d-d9699f522f922010-07-21T10:54:14-04:00 b5184609-c247-4eb1-80e4-6539ccfc051b2010-07-21T10:54:14-04:00 Do the Li-Ion batteries exhibit any of the safety concerns that are prevalent with the Li-Po batteries that we all use today? Specifically, can you charge them safely, in the airplane, indoors, without fear of a fire if something goes wrong?<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /> Yes and no. - They are a Lithium based battery, because of this there is always potential for mis-use or improper charging, which could result in fire. The good news is the higher quality Lithium Ion raw cell manufactures have built Safety into the cell. Fromeco use batteries from these manufactures. - Lithium Ion Cells have 3 different types of Safety Features. 1) The have a vent, this allows them vent off pressure. 2) They have what is called a PTC, this devise can be thought of as a Thermal Fuse, (sort of, more to it than that but this are lamens terms). The PTC will expand if the battery is over amped, this will cut off current flow in an attempt to save the pack in a massive over amperage situation, direct short and the like. 3) Some Manufactures use a Fusible Matrix between the chemistry that blocks all electron flow once it reaches a set temperature, this is not reset able like the PTC. - Lithium Polymer batteries have none of these features, this works to their advantage when it comes to weight, and all out discharge rates. This what makes them so appetizing for electric flight power applications. Unfortunately they have no way to vent, think of the (silver sausage) effect. It also creates a problem in the fact that as the pressure increases so does the temperature, the higher temperature the more volatile the battery becomes. - Lithium Polymers have no over amperage protection, this allow the end user to use them past their max rated current and possible damage the cells. This damage may become evident when the battery is charged again, or down the road on charge 50 or 100. - Lithium Polymer cells are typically used much much harder than a Lithium Ion cell. This creates a problem with pack construction. Since Lithium Polymers are usually stacked in a sandwich format, the cells in the middle of the sandwich are usually running at a higher temperature than their outside brothers. The Temperature variant actually allows for the cells that are running at a higher temperature to discharge a slightly higher rate than the cooler cells. This can cause an imbalance situation down the road. Which inturn can lead to an overcharge situation. These are some of the differences between the batteries. The Ion cells are safer than the Polymer cells by quite a margin, however they can still have problems. 8b9c901d-992f-419e-ad0b-1d25ad9bff8b2010-07-21T10:54:14-04:00 I bought a lightly used 30% plane with Fromeco 2400mah lithium Ion packs onboard. I suspect the packs are 1-2 years old. In your FAQs you said Lithiums have a nominal life span of 2 years. Will the batteries degrade slowly or all at once? In other words, would I be able to do a discharge test to track capacity and note any decreases or will the battery simply fail one day? It has been our experience that they degrade slowly, loosing life as you go past the 2 year mark. Unfortunately Fromeco does not have alot of data in this area. There are many factors that affect the rate of degradtion, and how fast that it will happen. Things such as storage temperatures, storage rates (Voltage), and how the battery has been used during its life. 1f315676-c7e9-4d50-bc6a-e4f978c14d7c2010-07-21T10:54:14-04:00 I have a 27% EXTRA with 5 HST-5955 digital servos and a DA-50R engin. For this size plane and digital servos what is the recommended battery, regulator and switch setup. We would still recommend a 4800mAh pack for RX and a 2400mAh Pack for the Ignition, the 5955 are power hungry servos however the 4800 will still get the job done on that size of plane with that many servos. We do recommend that you monitor you system closely on the first flights to get a good idea of what kind of flight time you are going to get out of your RX battery. 7b934bb6-a49c-480b-ab26-4705885e5de22010-07-21T10:54:14-04:00 fb1796d5-637a-4da8-9de5-107930759bd12010-07-21T10:54:14-04:00 What is the difference between peerless and reilon?

I would like to know if I should be aware of any potential performance issues with using my batteries in low temperature environments (Canada) during the winter time. How will the batteries perform below freezing point from 0C to -20C? During the Winter time we get this question quite alot. - Charging Batteries should be charged at temperatures Higher than 32F / 0C - Discharging At 32F / 0C Batteries capacity will be 90% At 14F /-10C Batteries capacity will be 70% At -4F / -20C Batteries can freeze. This will cause irreversible damage do not allow this to happen. 6780386b-c4cd-4db5-afcb-d4c874b0d3da2010-07-21T10:54:14-04:00 Can I safely use the Dynamite Vision Peak Ultra charger on my 2400 Relions? Fromeco does not have any hands on experience with this charger, the specs do state that it would acceptable to charge our batteries. The manual only states that it will charge Lithium Polymer, however the charge settings for Lithium Polymer and Lithium Ion are exactly the same. 4fead319-f20d-40e4-9c26-b1439ab61bfa2010-07-21T10:54:14-04:00 I have a Hobbico MKII pro series charger,and it says it will charge 1to3 cell li-ions. Does this mean I cant charge a 4cell 4800 fremeco relion. No You will want to charge a 4800 on the 2 cell setting this will be the 7.4 VDC setting . Yes there are 4 cells there however they are 2 x 2 in parallel. So they are double the capacity but only the voltage of a single 2 cell pack. 10313477-164c-4455-8ccc-e2edc435f2d22010-07-21T10:54:14-04:00Can I use the MRC superbrain 969 charger to charge your 4800 li-ion relion packs?

The LiIon program doesnt charge to full capasity. Lars Yes you can and we incorage that you do, you are right the charging Regime of the 330D for a Lithium Ion only allows for a 7.1 Volt charge. The actual charge Regimes are the same however the Lithium Ion terminates .2 VDC too early. This is due to the charger using an older design charge controller for older Lithium Ion batteries that used to terminate at 8.2VDC instead of 8.4VDC. 9356ac2a-f7f8-42f5-9822-48ffbf7280a42010-07-21T10:54:14-04:00Yes you can, however they do not share the same reciprocity.

It was designed to be a drop in replacement for holes already produced for those switches. 2fa28e07-5a46-4e7c-b674-5d9b0ee38a992010-07-21T10:54:14-04:00 Using your regulator in an aircraft,what happens if the voltage of a 2s li-po gets down to 6v while in flight? Im thinking about using an 1800mah 2s li-po in a Carl Goldberg yak-54, 25-27% size with 8 standard servos. Fromeco encourages you to please read more information in the knowledge base. If you run your batteries down to 6.0VDC while in flight under flight loads you undoubtably crash your aircraft so please do not do this. Your batteries should be charged when they hit a Voltage of 7.0 under a 1amp load. cda765ff-926c-402a-be94-598b651e05202010-07-21T10:54:14-04:00 Discharge Li Poly (and Li Ion) batteries to prevent capacity loss.... Weve just had a club meeting where some of the electric flyers insist that you should discharge your LiPoly (and probably Li Ion) batteries to 70 - 80% of their rated capacity for winter storage. They claim that doing so will prevent long term capacity loss that will occur if you leave the batteries fully charged and sitting over the winter.... Would you care to comment on this myth... true, false or it depends??? False! Hopefully there was a cash wadger involved, and you win the bet? Storage of any Lithium Ion or Polymer battery should be done at 1/2 to 1/3rd or 30 to 50% charge. That would be 7.7 to 7.4 with our packs. aedcea18-e8a9-4e0a-8187-7a940af6ddbd2010-07-21T10:54:14-04:00 Recommendations on how to lower the voltage of Li Ion batteries down to the 7.7 - 7.4 range for winter storage? Fromeco does have something of this sort in the works, however right now we do not have one. What I would do is use a Triton or similar charger to discharge your packs. If you don't have you could barrow one. The settings you would use is set the charger to discharge the packs down to the 7.7 to 7.4volt range, do this at a 500mah rate. If you can't get you hands on anything to discharge with you could use a DC Car light to discharge, or you can go to a hobby shop that sells lots of RC car equipment, they usually have discharge light bars for RC car batteries, this will work also. If all that fails you can turn you stuff on and wiggle sticks utill 2am in the morning, not the best idea we know but it will work. NOTE: While the 8 ball does put a load on the battery the time it would take to discharge a battery by repeatidy testing would take forever, and there is a good chance something would get burned up due to heat load while doing repeated testing 100s of times. 16fb40f6-1cca-4f38-9fc0-f7b3789db35c2010-07-21T10:54:14-04:00 24b6401e-21b0-4864-b9f9-d48a8e560a042010-07-21T10:54:14-04:00 Do your battery come with balancing TAPS, if so which ones, or can I get them with Thunder Power TAPS. No Fromeco Lithium Ion packs do not have balancing taps, so there is no need to use a Thunderpower charge balancer. The Lithium Ion batteries really don't need to balanced to that extent. They will stay balanced under normal use and charging just fine. There are severial contributing factors as to why Lithium Polymer batteries need balancing Taps, Lithium Ion batteries do not share these factors. This is due to the type of service these batteries will be in. 9517661f-fdf7-4143-a82a-af52f698a7932010-07-21T10:54:14-04:00 a68a24ea-5a38-411c-870d-597f1492bd792010-07-21T10:54:14-04:00 can i use a accu cycle charger with your batteries Yes you can with out issue. cf5a645d-721f-4100-99b4-2f6eeb064bed2010-07-21T10:54:14-04:00 d0f10179-9580-4263-a0fd-71d356ad0dae2010-07-21T10:54:14-04:00 Q10177 - INFO: There is information on battery University website that lipo are not to be stored fully charged for a long period and the cooler the tempature while store the batteries will maintain charge capacity. My question is if I can put my batteries in a deep freeze for the winter? That same info can be found here as well there is a link below to take you to the knowledge base article with that information. To answer your question it really depends on the Term "Deep Freeze" how deep are you freezing them. You don't want to go any deeper than -20C, as long as you follow that rule you will be fine. One word of caution, if you are storing the batteries in ultra low temps, be sure to warm them up before you charge them. It is not good to charge the cells or any Lithium Ion cell at ultra low temperatures. 243f3afd-9232-4346-9905-ce2ab2c049eb2010-07-21T10:54:14-04:00 d00f338f-d23e-4012-9f59-fce13b9987872010-07-21T10:54:14-04:00 745c4c05-6db7-4b74-aefb-3eb285528a902010-07-21T10:54:14-04:00 I just bought the Relion pack and regulator from a friend and I am wondering can I use my TP 1010 Charger to charge the pack? Also I was wanting to know how to set it up since this is my first rx pack, I have always used a SBEC. Yes you can use your TP1010 charger on our batteries, you will want to set it for 2 cell, or 7.4VDC, your charge rate should be no higher than 2amps. The critical setting is the Voltage or VDC so make sure that is set for 7.4. 3c41a675-bce1-4c2b-9c16-cb7c522644bf2010-07-21T10:54:14-04:00 a584ac64-f039-473c-9981-adc2abda9cb72010-07-21T10:54:14-04:00 I am running 9 jr8611as into a r149dp on a 35%. I have 2 peerless 2400s, regs(5.98v), and switches going into the one receiver in seperate ports. Should I have any concern about the load draw thru the receiver? One of my batt pack draws down more rapidly than the other. Is that normal? Your Receiver will be fine. The main bus will be able to handle the load you are going to be subjecting it to. Your batteries discharge. You want to make sure that your Regulators are matched one more digit over. For example you gave a number of 5.98VDC. You will want to make sure that it is reading 5.980VDC, and then make sure that the other Regulator is running anywhere from 5.977 to 5.983 volts. If you go to the Fromeco Skunkworks, you will see we are about to release a new product called the Wolverine. This new switch will take care of the Balancing battery issues. You will still need to make sure that your regulators are properly matched, however if they are not it will not effect the batteries, it will only mean that one of your regulators is doing all the work. b5d8f3a2-7caf-4c74-9cc9-9f674663b4032010-07-21T10:54:14-04:00 I am running a DA 50 with 5, hi tech 5955 and 1 5625 for throttle and a futaba 3010 on choke, I would like to get 8-10 17 min. flights per charge. will dual 2400 be ok or should i go with the 4800, thanks. The set up you mention with the dual 2400mA packs is the perfect set up for this size plane. We try really hard to NOT quote how many flights you will get on a certain set up. This is due to the fact that everybodies set is different, some are more efficient than others, and everybodies flying style is different. We would recommend the 2400mA packs over the 4800mA packs. 8966bb01-aa73-4536-9006-61a3c4fbd1032010-07-21T10:54:14-04:00 I have a original Triton charger. No matter what type of battery I try to charge it quits in 3 to 4 minutes. I must have a setting wrong but I cant find the one that is wrong. Can I get all the settings for the following battery? Nimh, 4 cell, 2300mh. I have been through the manuel seting many times and I am still at a lost. First let me state we by no means Triton Experts. Your settings should be a NiMH 4.8VDC and I would try setting the amperage at a very low rate like 500mAh's at first just to get your Triton to work. This battery could charged at a much higher rate, however taking into consideration that you are having problems I would start out low and then bump it up after I got the charger to work. As to what may be causing your problem???? From the information that you have given us, it sounds like a power supply issue, dead battery? Bad Power Leads, insufficient AC/DC power supply?? I don't know, if it has the same problem on every battery, I would check there first and work my way towards the charger. Not much help I know, but better than nothing.. One thing you may want to do is find some one else that has one, and either test yours out on their power supply system or have them look at yours to see what you may be doing wrong? 67195615-feeb-4b1b-892f-00c5f978271f2010-07-21T10:54:14-04:00 How do you charge a 5200 pack on a triton charger?How many amps etc...?

The Triton will charge at up to 2.5 amps, however the only way to achieve this charge rate is by ensuring that you have heavy charge leads and connectors. In this section of the Knowledge base there is other mention of use of the Triton with Relions, and things should be done to optimize there use together. ef4df5c8-0d86-4863-b20f-25d2dfd592272010-07-21T10:54:14-04:00 I am getting a 50cc sized plane and want to know what you guys recommend. Since you dont sell 4800 maH packs any more is it alright to use one 5200 maH for the receiver and one 2600 maH for the Ignition. I am guessing I will need 2 regulators and does it matter if its a reliaswitch or "The Regualtor".I will need 2 switches and will all the connectors from all these components from Fromeco work in a Futaba Receiver? Also can you give all the chargers and voltmeters out on the market that I can use? Yes your set up is a good one, and is what we would recommend if you were to call us. The Regulator and the Reliaswitch are built on the same Regulator Platform, the Reliaswitch just has the ability to be used as a switch. The choice is really up to you. On thing to keep in mind while making that choice is the Reliaswitch uses power in the off Position, batteries should be unplugged if being stored for long periods of time. All Fromeco Equipment comes with JR standard for leads that would plug into a RX, this gives compatiblity with all Radio Systems. There are Hundreds of chargers out on the Market that can be used, what you are looking for is a charger that can charge either Lithium Ion or Lithium Polymer, it needs to be able to charge a 2S pack or 7.4VDC. The Triton Line of chargers work well, for first timers, but can only charge one battery. Load meters, again lot on the Market. We make one, Hanger 9, Futaba.......and so on. What you need is a load meter that puts a 1amp load on the batteries for 7 to 10 seconds. 6899ebc7-963f-4eac-87cb-fe6888cec5bf2010-07-21T10:54:14-04:00 I have a Fromeco 2400 (ign.) & a 5200 (rec.) in my plane. I have been using a Triton charger. It works but it takes almost two cycles through the time limit on the charger. (2hrs limit) Ive been thinking of getting a Reliacharger but now I see you have the new Ion Cube. What is the advantage of the Cube over the Reliacharger? Also, will a deep cycle battery work for a power source? (I see you are recommending a plug in type power amp supply) On your Triton, you need to make a larger set of charge leads. Your charger is probably not charging at the full 2.5 amps that it can. To enable it to do this you must increase the size of your charge leash in wire size, this is to reduce impedence or resistance. Using a good connector like a deans also helps, and making them as short as possible also does not hurt. Your Tritons timer is adjustable. The Ion Cube in its Basic Version is very similar to the Reliacharger. The Ion Cube is easier by the end user to add channels to, or the GUI Card (Graphics User Interface). When you have the GUI installed, the charger it is much more versitile than the Reliacharger, users can see charge rates, battery VDC, and mA's put into the battery. Yes a Deep Cycle Battery will work just fine, you do have to make sure that it is keep in a state of good repair, (Charged). c1aedf6f-ae75-4707-8343-0dab10d72f5c2010-07-21T10:54:14-04:00 I have a new Ion cube 3 port charger with a brain and used it for the first time last night to charge 3 5200 packs at 1/2 amp charge rate and noticed that the fan wasnt working. Do I have a problem, or at the low charge rate the fan is not needed? Great Question? You are correct, Ion Cubes with Brain Board installed will control the fan. The Fan will only come on when a charge rate greater than .5 (500mAh) is acheived. So if you program your charger to charge at .5amps it may hover at .49 or less as the battery gets close to full charge, the fan will not come on. As soon as the charger goes over .5amps the fan will come on to cool the charger channels. NOTE: On Ion Cubes with out the Brain Board the chargers Fan will be on all the time 6d149616-ca50-4d71-9606-d76886967e3f2010-07-21T10:54:14-04:00 f55bf40c-2a7f-4534-90ad-4999d4dda2522010-07-21T10:54:14-04:00 Have the 2600maH Peerless Li-ion packs discontinued? I do not see them on your website anymore. Yes we have discontinued the Peerless Line of battery packs. They were not discontinued because they were hard to get or they had problems. They were discontinued due to the fact that the new Relion batteries actually out preform the Peerless line of batteries. 3fc1c2e2-fa1d-40c1-a58b-8517efed36612010-07-21T10:54:14-04:00 I do not know if you are fimiliar with the Swallow charger, but my question is can one charge the 2600 Relions with this charger? Yes you can. As with any charger you are using for the first time, it is a really good idea to monitor this charger and make sure that it is opperating as it should be. 43c59cf2-7990-404b-8925-1bedef1e0bd32010-07-21T10:54:14-04:00 976e8174-24da-4868-9e63-5a8b4a01203b2010-07-21T10:54:14-04:00 Will the Ion3 charge the Relion 5200 since it is a 4 cell battery? If Im reading the specs right it shows this charger detecting 2 and 3 cell only. You bet. The Relion 5200 is a 4 cell pack physically, however as far as a charger is concerned it is really only a 2 cell. This is because the 4 cells are paralleled together making the battery a 7.4vdc pack or 2 cell. e39f327b-c403-44e2-a6e6-427724569e232010-07-21T10:54:14-04:00 d85b9158-e50d-4846-b467-6cf60bc40f9b2010-07-21T10:54:14-04:00 What is the upper limit on ambient temperature for storage? I ask because I keep my giant scale planes in the garage, and in the summer it can get as high as 110 in there. I currently use NiCd batteries for those since they can take more abuse. Could I use LIon? I really dont want to remove the batteries between flying sessions. I use your LIon batteries in my helicopters because they stay inside. BTW the 5200 is great, I can fly my helis all day without recharge. We have included a link in this Knowledge Base to the information you are asking about. cdcc3bc5-2118-4eae-ba0e-77031d3d0b602010-07-21T10:54:14-04:00 What is the upper limit on ambient temperature for storage?

Even though the swallow gives you the impression that it will only be able to charge the batteries up to 5000mA, what it is really asking you or telling you is; you are going to be charging at a 5 amp rate for the constant current phase of the charge cycle. By setting the charger to charge at 5amps or 5000mA, your battery is still going to charge to 8.4VDC which is the real indication that your battery is fully charged. As long as your charger shows 8.4VDC when it is done charging you can be pretty confident that it put in the full 5200mA's. e70ce224-ee7c-40f3-9920-085d2cee1bb62010-07-21T10:54:14-04:00 Can i use a robbe power peak lipoly 300 charger with a Fromeco Peerless 4800Mah LiIon batteri? I can't find any information on the charger called out by the name you have stated. I have seen plenty of Power Peak chargers in different variations. I would say the the charger you mention above will probably work just fine. The charge regime between a Lipo and LithIon are exactly the same. All you need to make sure of is, your charger can charge at a VDC of 7.4VDC and your set. 7f8f7be5-0751-447c-bbba-e29464455e352010-07-21T10:54:14-04:00 Will the batterys drain down if left connected while sitting using your badger switches like the reliaswitches? Technically yes, however the rate of discharge is actually lower than a Lithium Ion's self discharge. The Reliaswitch draws much more power in the off position than the Badger. 0dc34cc8-8347-498f-b51c-40c83545295a2010-07-21T10:54:14-04:00 At what amperage should I normally use my Ion Cube to charge 5200 Relion packs? Thanks again. Fromeco recommends a 2 amp charge rate for all of its batteries for continuity across both line. However you could charge your 5200mah Pack at 2.9Amps is choose to. Slower is always better with batteries. However with the Ion Cube and Fromeco cells the choice is up to you. dcad0772-44fa-472c-bcce-9b52efe78afe2010-07-21T10:54:14-04:00 1ac751bc-c8ca-4d28-a95e-773fb274615c2010-07-21T10:54:14-04:00 ca32fd82-fc16-43a0-a843-1f9f3be192332010-07-21T10:54:14-04:00 9a7ee203-4f79-4d3f-b1b0-e301367c73a32010-07-21T10:54:14-04:00 Have got a new Peerless 4800, now you say its 7.4V LiIon but my charger has settings for either LiIon (which is 7.2) or LiPo (which is 7.4), in which mode shall I charge (Multiplex LN 5014) ? You will want to charge at 7.4Volts. The 7.2Volt setting is for older Lithium Ion cells that are not very common any more. ee30fcd1-6f8b-4121-a7d0-9aebb7b4fd872010-07-21T10:54:14-04:00 Ref basic ion cube just purchased. I am using a 12 volt 16ah gel cel to power cube. Spec indicate a default charge rate of 1.5 amp but actually measuring charge current to 2600 ma battery (new) with Fuke 87 meter equals 860 ma charge rate. Battery read 7.29 at 1 amp load before starting charge. Will the 13.8 volt power supply you suggest get the charge current to 1.5 amp? Does the charge rate fall off as battery is charged, thus maybe closer to 1.5 amp with fully discharged battery? On a single battery your 12 Volt Gel cell should be getting the Job done. The charge rate does fall off as the battery reaches fully charged, however this does not happen unit the battery reaches a voltage of about 8.4 Volts. This depend on the length of charge leashes and how much equipment you have between the battery and the Charger, (switch, charge jacks and so on). We would like it if you give us a call Mon-Wed so we can ask you some more questions. Some information that would be useful is when you did your amp test what was the VDC of that battery at that time? What is the Voltage of your power supply. f833d961-50a1-4116-9ceb-fdb179c271b52010-07-21T10:54:14-04:00 d24d1226-6fd5-4a51-aabd-1fcce90425082010-07-21T10:54:14-04:00 76f41b1d-57f6-45a7-b374-468b4d81d07a2010-07-21T10:54:14-04:00 af428cb8-6916-4cf6-a5e3-a50ab67d335c2010-07-21T10:54:14-04:00 I had a heli in the back of car which switched on via the pin falling out of the fail safe switch. Not sure how long it was on but maybe an hour, 4800 peerless after hard days flying. I pushed in a replacement piece of wire which i saw definately switched off the battery and reg, however at the field today the pack was dead, would not even register on the 8-ball checker.
