Wholesale 🧨 Mon Ster 24 Volt 250 Watt Universal Speed & Voltage Controller 😉

24 Volt 250 Watt voltage/speed controller for electric scooters, bikes, go karts, and mopeds. There are eight connectors: motor, battery, charge, derailleur, lock, brake, and brake signal.

These are the most common wiring connections found on electric scooters. However, depending on your make and model, you may need to cut and splice a few, but not all of the wires.

This controller is compatible on most 24 Volt products equipped with 180-250 Watt motors.

Controller connections as follows:

Battery Connector (Black & Red Wires, Thick)

Battery wiring. Black to Black, Red to Red.

Motor Connector (Blue & White Wires, Thick)

Motor wiring. Blue (controller) to Blue (existing wiring), White (controller) to White/Yellow/Brown (existing wiring).
