id suggest the 100a turnigy, but you need motor brakes.... wny not some rear discs on the wheels? itll handle 12s. get a pair of 6s. and a series connector... and a kb45xl....
Sorry for the confusion. I have 16 a123 cells 4 3s1p packs and two 2s1p packs. So I can run 12s1p or 6s2p...etc. I am only running 6s2p because I don't have a controller to run a higher voltage. 12 cells, whether in 12s1p or 6s2p will have the same power output. I will just have to pull more amps to get the same power. I know thats not ideal, but it will work for now. I am really looking at the 55-10-32 kontronik. It has proportional brakes right?
