Storage Care and Charging of Lithium Ion and Polymer Packs

Basic Charging of the Fromeco Relion and Peerless line of batteries.

• FROMECO receiver packs must be charged with a lithium charger set to "2 series" or "7.4 volts"
• After charging, FROMECO receiver packs must not exceed 8.4 volts
• Charge FROMECO receiver packs at  a rate not to exceed 1C.  Use a lower rate (0.5 to 0.8) for longest life.
• FROMECO packs should be charged at temperatures above 50F (10C)
• Do not store lithium packs at temperatures above 140F (60C), because cells may degrade.

Storing your Fromeco Batteries Relion and Peerless, for 2 Months or longer.

• Discharge packs to "7.7-7.4 volts" or to about a 1/2 to 1/3 charge.
• Monitor batteries regularly, ensure battery voltages remain above "7.0 volts".
• Please do not store batteries fully charged, sells may degrade under a full charge if stored for long periods of time.
• Lithium chemistries have a nominal shelf life of 2 years, it is always a good idea to write the date you receive your Fromeco batteries on the pack.
• Lithium batteries store best at "below room temperature (between 0C~32F and 25C~77F)"; Fromeco recommends that you store them no lower than Freezing or 32F~0C.  DO NOT store at extremely cold temperatures: keep temperature greater than -4F (-20C).  The electrolyte will freeze at approximately -40F (-40C).

Discharging packs to test capacity.

• Fromeco Lithium Ions do not need to cycled. 
• When checking capacity of a Lithium Ion, do not discharge packs lower than "6.0 volts".
• Discharging below "6.0 volts" will provide no usefull data and may degrade the cells.
• Nominal test discharge rate (per cell manufacturers and industry standard) is C/5.  Test load should be under 1A.
• Please recharge promptly following a test discharge
