Labeled Connectors: The three identical connectors with black and red wires going to them are labeled on their bottom sides for easy identifications. The rest of the connectors have unique wire colors so they do not need to be labeled for identification.

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 20.5 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.
