Sealed Design: This speed controller is factory sealed with black silicone sealant around its wires and case seams to prevent water intrusion.

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 31.0 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. Connecting a brake switch to this controller is an optional connection.
