Maximum Current   13 Amps
Rated for Chargers   Up To 3 Amps
Conversion Efficiency   95%

Versatile Motor Power Range: Works with 12 Volt motors that are 150 Watts and under. Designed for 80 Watt, 100 Watt, 120 Watt, and 150 Watt motors.

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 10.5 Volts ± 0.5 Volts)
Motor Cut-Off During Braking: When the brakes are engaged the brake switch signals the controller to turn off the motor. The motor resumes running when the brake is released.
