    We use Quality parts to ensure a smooth and cool operation of our internal motor controller.

    Great care has been taken to make sure our controller is sturdy and has a lot of headroom for current draw. Ensuring a prolonged continuous operation at 50A.

    The Passive heatsink design with dual bank temperature sensing ensures a safe operation at peak performance without the need of a cooling fan. (operation with a fan can be done in cerctain circumstances)

    Integrated per cycle overcurrent protection hardware limited to 75A ensures the controller will regulate the power to the motors in any overcurrent scenario, protecting the motor controller bridge and the motors.
