Heat hurts batteries, yes.
Over dischargin them can be the worst if not done properly. Most overlook that. You should NEVER discharge below .9v per cell. NEVER! If you use a light bulb dimmer and have no way of knowing, then I suggest pulling them off as soon as the bulbs start to dim. Equalizing trays/dischargers with voltage cutoffs are probably best to have. Fortunately, my charger has a preprogrammed cutoff when discharging of .9 v per cell. This alone is a HUGE bennefit.
After your runs it is best to let both the motor and the batteries cool down before discharging your battery pack.
Heat = Bad !
The answer is yes.
