The thickness of the shell is increased, and the heat dissipation is better.2. Circuit board solution and main program replacement.3. Replace the power tube.4. Replace the capacitor.5.The copper bar is thickened and the inductance accuracy is higher.The uphill torques of the controller is increased, the power is strengthened, the speed can be faster, the smoothness of the drive motor is better, and the life of the controller is longer.Can support 48V-60V-64V-72V universal. 1 x MotorController Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
