Yes the 2 caps the neg wire and what I believe to be an inductor all came off from the heat. I got the esc about two or three weeks ago from here. The caps are fine a little burned from the fire but the ends are still flat.
The pack was charged sometime last week. I just cycled it on my Duratrax ICE on a 2A discharge it still had a little over 600mah in it. Its a 1100mah pack.
I personally think When the battery disconnected, the connector must have touched something that conducts eg metal and shorted the circuit, are you running a gorilla/supermaxx chassis?
