OK, I have 2 Razors for my son one has 2 new battery's. 2 12V (24V) 7amp. Which it calls for. If I were to bump the other one up to, 2 12v (24V) 12 amp. Do I need to do anything to keep anything from burning up? I'm new to the electric go carts. And im sorry if this question has been asked 2 dozen times.
