Designed for 48 Volt DC electric scooter and bike motors up to 2000 Watts. Can be used as a heavy-duty controller for a single 1000 Watt motor or can run two 1000 Watt motors at the same time. Maximum current 60 Amps. Under Voltage protection 41 Volts. Current limiting feature helps prevent controller damage due to over-current conditions. Under voltage protection feature helps prevent over-discharge and extends battery life. Compatible with all standard 3-wire variable speed hall-effect throttles.

Two Thick Red Wires: The two thick red wires are connected together inside of the controller so it does not matter which thick red wires go.
Requires Heavy-Duty Switch or Power Contactor: This controller does not have a built in power relay to turn it on and off. A heavy-duty power disconnect switch such as item # SWT-700 or SWT-705 or power contactor such asitem # RLY-24150 is needed to turn this controller on and off. to the battery pack or motor.
Under Voltage Battery Protection: When the battery pack falls below a specific Voltage the controller turns the motor off preventing over discharging of the battery pack which extends the battery packs lifespan. (The cutoff value is approximately 41 Volts ± 1.0 Volts)
Motor Cut-Off During Braking: When the brakes are engaged the brake switch signals the controller to turn off the motor. The motor turns on again after the brakes are released.
