What happened (MM and Lipo)

[junkman]

I forgot and left one plugged in one time for 2 or 3 weeks, the pack didn't puff, but wouldn't take a charger. It was a 3s pack, and I was able to recover 2 of the cells, and honestly I haven't really noticed any drop in their performance. Seperated them, and charged them at .25 amp nicad setting to get them up to where they would take off on lipo setting. I don't really understand if it was switched off the the extreme draw. I could see if he turned off the transmitter, and put the truck up, without shutting off the switch, then it glitched wide open or something. That is wierd.

Can confirm that the esc still draws current when its turned off. You have to disconnect the batts otherwise you can kill your lipo as your friend found out. This is pretty common knowledge though so its nothing new.

No clue about the unsoldered motor wires though. If it did get that hot by whatever mechanism, he's lucky it didn't start a fire.
