I can't explain it, but though I've charged Li Poly batteries with no problems.
The kokam 3S 1500 mAh battery I purchased from FMA Direct would not at first take a charge. Returned it and they graciously checked it out. Found no problems and charged two times before returning it to me.
I check it out to have 12.6 V. After about 30 minutes of flight time, time to recharge. I did everything correctly. Tried disconnecting and reconnecting all connectors and the Triton charger kept coming with "end" within seconds.
Frustrated, I took the whole system to a friend. He did exactly the same charging procedure and presto! The battery began taking on a charge, voltage checked out to be 12.6 V.
Does he have "magical fingers" or what?
Well! Wan
