Big power controller.

These kits cost us a fortune, and we have to order enough to make it commercially worth while.

Battery Compatibility:

Big power motors need big battery output. Our existing 72 42Ah and 72V Dominator were designed to run the standard Sur Ron motor,  and can not power these motors to their full potential. We recommend 190A DC on your KO controller and 500A Phase amps.

Our Dominator V2 72v 55Ah  we recommend 220A DC and 600 Phase


Controller Specifications:

Input Voltage: 40-100v
Max Phase Current 800A
Max line Current 400A
Peak Output Power 35,000 Watts
Water Penetration ip67
Operating Temp -25C to 80C
Max Efficiency 98%
