Features1ABS Waterproof Display: The display panel is made of ABS material, ensuring lightweight, durability, and resilience. It is finely crafted, providing superior protection and waterproof performance for the internal circuitry, making it highly durable. 2Efficient Heat Dissipation: The controller's housing is made of metal with grooved design, facilitating efficient heat dissipation and effectively safeguarding the internal circuitry from overheating, ensuring optimal performance. 33 Mode Operation: This controller offers three working modes for the motors. In normal operation, the motors automatically run in sine wave mode if the motor hall is intact. If one motor hall is damaged, the system automatically detects and repairs it. If all motor halls are damaged, it switches to hall free mode, ensuring accurate phase recognition when the motor hall is in great condition. 4Versatile Voltage and Power: Support for 36V 48V voltage, 1000W power, and 38A current limitation, with low voltage options of 30V and 42V. It is suitable for enthusiasts who enjoy challenges and DIY projects in electric biking. 5What Will You Get: This kit includes one brushless controller, half throttle grip with display, one handle, one accessory and one specification, making it suitable for electric bike and scooter modification.SpecificationItem Type: Electric Bike Controller KitMaterial: ABS, aluminum alloyWeight: Approx. 693g/24.4ozVoltage: 36V 48VPower: 1000WCurrent Limit: 38ALow Voltage: 30V 42VPackage List1 x Half Throttle Grip withDisplay1 x Half Throttle Grip1 xHandle Grip1 x Accessory1 xController1 x Specification
