Well, I toasted a LiPo last week and after messing w/ it some, it's hopeless I think.
I have been charging my 3S packs using both computer balance chargers and the generic esky balance chargers (I have 2).
I did not mind the esky charger cause I can just plug it in and it's done in the morning. I typically only get 3-4 flights at lunch anyway.
Well, one of the crimp pins had been slipping out of the blanance charger jack and the charger was thinking it was a 2S or something. I have been making it a habbit of testing EVERY pack I put on the heli with a little Lipo board like this one:
I have 4 of them, one in each Tx box plus one in my battery box and one by my chargers.
I am not sure if this particular pack was a failed charge or if something else happend but I plugged it in to test it before the flight and cell #1 was reading 1.5V.
I tried to charge it on the computer charger but it would only put in about 500mAh and it was not holding it's charge. The charger showed cell #1 IR of 235 milliohms and the other 2 as about 20 milliohms.
I guess I'll have to go through the procedure to kill the pack after stripping the deans and balance plugs off of it.
