How hot did the battery pack get while in your car- fully charged and high temps can be bad for the pack.

Either way, get in touch with FlightPower they'll surely help you out.

Never, ever, ever, ever give up.

They say a parked car will heat up to over 40F above ambient in an hour, more if left longer. In Pamona it is 90F this time of year, so you left your batteries in a car that was well over 130F for a long time, and fully charged at that. The batteries did what any battery would.

FYI... voltage rises with heat. You, in essence, over charged your pack. The voltage went well over 4.2V/cell in the heat. This is the same reason why you are not supposed to charge your batteries when they are cold... as they warm to room temperature, the resting voltage goes over 4.2V/cell.
