Product parameters: Color:Blue Condition: 100% brand newItem type: Motor Controller Material: Aluminium alloy Voltage: 48V-60V-64V-72V-84V Weight: .1044g Power: 2500W-3000W Current limit:45A-60A Tips This color is the color under strong light/sunlight, it will change during the light period, if you mind, you don't need to buy it. Thank you so much. Function 1. Increased withstand voltage and increased adaptable voltage:48V, 60V, 64V,72V, 84V,universal 2. One-line instrumentation adds more adaptability, about 80%. 3. In terms of hardware: thicker aluminum shell, better heat dissipation. The motherboard ,solution is better. Power tubes, capacitors, copper bars, etc. are better. 4.Suitable Motor Phrase Angle: Auto recognition. 5.Suitable for: Electric motorcycles,Small tricycle,Two-wheeler etc 6.Package List: 1 x Brushless Controller Line Description 1.

Connect wires 1, 2, 3, 4, 5, 12 Step 2. Connect the No. 5 wire with the motor suspended. (Note: the motor needs to be in the overhang position for docking wire #5) Step 3. The motor will perform a forward/reverse state. (If there is a reversal you will need to disconnect the 5 wire and reconnect it) Wait 10 seconds in the forward state to complete learning. Step 4. Make the wiring connections according to the vehicle.
