     * You'll also want to consider **larger gauge phase** wires.  Larger gauge phase wires helps with pushing higher current(amps) into the motor with less heat loss(power loss) to the motor.  Hot wires can mean an exponential loss of power to the motor. This is only necessary if you plan to push more than about 80 battery(continuous) amps.
