Did you charge the battery while it was still in the vehicle?[X(]
I always charge my batteries in situ...they're usuall buried deep within my rc's, most of the time stuck down with 3M trim tape so aint coming out in a hurry, never had a problem...i did leave a switch on once and fried my servos so always check connections etc carefully before i start.
looks like this was a case of incorrect polarity, wall chargers are so weak you can leave them on for days without a problem...(done that before)
