?Product parameters? ?Condition?: Since the process is die-casting and injection molding, the product itself will have small flaws, but we guarantee that the product and internal components are 100% brand new items. ?Type?: motor controller ?Color?:Orange+Gold ?Material?: aluminum alloy ?Voltage?: 36v-84v universal, after connecting the learning line, identify the voltage according to the battery condition. ?Power?: 2500w ?Current Limit?: maximum output 45A. ?Connection Instructions? step 1. Connect the positive and negative poles, motor phase wires. Step 2. Connect wires 1, 3, 11 Step 3. Connect line 14, and the motor is suspended. (Note: Before connecting the self-learning line, the motor needs to be suspended) Step 4. The motor will perform forward/reverse rotation. (If there is a reversal, you need to disconnect the line 14 and connect it again) Wait for 10 seconds to complete the learning in the forward state. Step 5. Complete the wiring with the remaining wires according to your needs. ?Function line description? 1. Hall sensor 1 2. Dedicated to differential motor 3. Low level braking 4. Anti-theft signal 5.
