U500 BMS-23

Product Description

Genuine original equipment replacement BMS board for U500 V3 ebikes.

  • Choose between 15, 23 or 32 ah version based on your U500 battery's capacity.
  • If your battery no longer charges to 54.6V, but stops at 50-52V, the BMS could be bad.  First have a technician check the charger, and that the cells are balanced, if both are OK, and the battery will not charge fully, then replacing the BMS should fix the problem
  • Installation must to be done by a qualified e-bike technician.  Attempting to replace this yourself without proper training could result in fire.
