Manufactured by Curtis (Model 1206HB-5201), this controller delivers a 250-amp output for reliable performance in compatible 48-volt electric vehicles.

Built to OEM specifications, this unit ensures proper integration with factory wiring and motor systems. It is a direct replacement for the original controller in supported models.
