HobbyKing battery problem????
I ordered a 4000 mah 4 cell from Hobby King.. I just finished the jet I'm using it in and started charging the battery. One cell is consistantly 0.1v lower than the other three cells. I've tried slow balancing, cycling etc, but I can't get the low cell to come up to 4.2 volts. Does anyone have any suggestions or should I just use it until it dies? (My guess is that the battery isn't going to last long even though I time my flights to only discharge the lipo to 80%). I'm also curious to see if it delivers the 20c stamped on the pack.
