Feature: 1. Durable Material and Durability: Made of premium ABS materials, the brushless controller can withstand high temperatures and abrasion, ensuring long term stable use. 2. Enhanced Motor Power: The motor controller effectively controls the motor, can significantly increase the motor's speed and power, effectively enhancing motor performance. 3. Sine Wave Controller: The DC controller uses a sine wave control method, ensuring stable and non fluctuating performance. It is compatible with QS hub motors or QS mid drive motors. 4. Battery Protection and Extended Battery Life: The controller is designed to protect the battery and prolong its lifespan. It also increases the driving distance, allowing for longer rides. 5. Self Learning Function: With the self learning function, the controller has excellent commonality, making it compatible with various motor types and providing better adaptability and performance. Specification: Item Type: Brushless DC Motor ControllerMaterial: ABS Voltage: 96V Phase Current: 450A Bus Current: 190A Number of Tubes: 24 Waterproof Level: IP67 Sensor Type: Hall Sensor Applicable Motor Power: ≤4000W (This value is a normal matching value, if you do not pursue torsion and maximum speed, you can float a power segment) Application: Applicable to electric motorcycle, electric scooter brushless dc driver. Package List: 1 x Controller 1 x Wire Harness Note: The controller is a sine wave controller, which is a brushless DC controller with self learning function. Generally speaking, it is well matched with the QS motor. If you want to match it with a new brand motor, some parameters need to be tested by yourself.
