NiMH batteries don't like overcharging anymore than any other battery but that's why you need a good charger that measures heat and charge. When you get to a certain point, the charger will shut off or go into a trickle mode. There's lot's of smart chargers out there. Your RC guy should have them or check with a ham radio shop.
