If you assume that Paul's low-cost controller will give up to 775 amps, and you use 2/0 cable, and you have 20 feet of cable in your car, then the voltage drop in the cable is 1 volt. This is a reasonable max. This is a loss of 775 watts. You also have losses in the contactor, the fuse, the controller, the Anderson connectors, etc.
