Valence (36v) 38.4v 50ah 1.92kWh U27-36XP

These batteries are all in working condition and they were recovered from hospital equipment. Medical batteries often don't get used too much so they are perfect for solar storage and many other applications. We open every battery to make sure they are balanced, all cells have good voltage, and also to make sure there is no water damage. These batteries are in great condition and all you have to do is add a 12s lifepo4 BMS.

These batteries have something that looks like a BMS but it is not. You will need to add a BMS to these. What looks like a BMS is actually a BMU which communicates to another system that will turn the battery on and off. Valence has one called the U-BMS as mentioned in the specs on the 4th photo but it is not guaranteed to work with that system. It is very easy to add your own BMS. You can open the front access plate and have access to all the wiring to add your own BMS very easily. The BMS right now just communicates to something else so it will not shut down automatically. It simply just communicates. At this price you can add a 12s lifepo4 BMS very easily and have an excellent battery that will last a long time.
