I want to run a Lipo battery in my clodbuster. I'm running a Novak Super Duty XR with two 12t double motors. I know I need the Novak Smart Stop Lipo cut off module. But what I don't know is what would be the best battery. I do a lot of racing so speed would be better. I 'm thinking Of a 4s lipo but I don't know what C or mAh would be best. Any advice would be great thanks.
