When I charge my P3A RC with the 57W charger the RC heats up on one of the right corners, presumably where the RC battery is. It seems to heat to around 40C or maybe more, even when the room is around 22C. I'm concerned it's going to slowly eat away at battery capacity if I let it charge at that temperature. Should I care? I think I'll put a fan in front of it, or set a timer for 25 minutes when a fan is not available.
