  • BAC2000 VS BAC4000?

            BAC2000 will be limited to 225A motor current where as the BAC4000 will be allowed up to 463A, about 350A in reality. Therefore the BAC4000 will have greater acceleration power and top speed compared to the BAC4000.


  • What do I set for Battery Power field option?

           You need to set your battery‘s peak specification which will be programmed to the controller prior to shipment. Watts = Peak Amps * Nominal Battery voltage (52V or 72V).  11000W = 152A * 72V battery.
