I have a Joysway Offshore Lite Warrior boat, which came with a 7.2 v 1100 mAh NiMH battery. I purchased a 1/10 truck, which comes with a 7.2v 3800 mAh NiMH battery. I'm going to run the truck mostly with lipos and was wondering if I can use the new NiMH battery with my boat. I understand that I shouldn't use a battery with higher voltage, but would using a battery with higher mAH hurt anything? If not, would it translate into more power or longer run times for the boat?
