Features1Brushless Motor Controller: Provides stable speed, quiet operation, responsive braking and direction change control. The phase angle and rated voltage of the electric bikes can be automatically recognized. 2 Materials: Made of aluminum alloy, it can provide internal circuit protection, which is good for heat dissipation and avoid thermal overload. 3Dual Mode Operation: When the motor hall is normal, it works in the hall mode, and when the motor hall is abnormal or damaged, it switches to work without the hall mode. 4Applicable Scene: Suitable for electric bikes, electric tricycles, electric four wheelers, electric motorcycles, etc., as long as the power and voltage match. 5Easy Installation: Cables and connectors are durable, ensuring low failure rates for extended use. Each interface has a different color for easy installation.SpecificationItem Type: Brushless Motor ControllerMaterial: Aluminum AlloyController Box: Approx. 17 x 10.8 x 5.7cm / 6.7 x 4.3 x 2.2inPower: 1500wCurrent Limit: 50APackage List1 x BrushlessMotorController1 xUser Manual
