RC, do you mean the battery cable, then that is #6 minimum. You can use something larger, some teams use #4. However there is not much improvement if you keep the wire length short.
#12 has been allowed in the past for circuits protected by a 40 amp breaker but the loss is significant. I recommend #10 for these higher current loads. At 100 amps a #10 drops 0.1 volts/ft. while #12 drops 0.16 volts/ft. (measure both red and black wires please.)
