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!!!
