Battery Charger Port Input: This controller does not have a battery charger port input connector like most other controllers do. The battery charger port needs to be connected directly to the battery pack when using this controller.
Speed Selection Switch: A speed selection switch can be wired to this controller to limit the top speed of the motor. This is an optional connection and if no switch is wired to the speed selection switch connector then the motor will operate at full speed.

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 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.
