NIU 17S 45A BMS

This is an NIU BMS pulled from either a 26, 29, or 35Ah NIU battery pack. It was tested to charge and discharge a battery before being pulled off of the pack. This does not include screws, wiring, or temp probes; I am assuming you have these from the battery pack and just need to swap a new BMS in. 

NOTE: very often the BMS is not bad. You might have one low cell, a broken temp probe, a broken BMS sense wire, or some other issue causing your problem. Try to rule these out before ordering.
