Valence U-Charge U1-12RJ LifePo4 Battery 12V 40Ah - Cut Cable

These were all recovered in working condition, are perfectly balanced, and include an installed BMS. These are plug and play.

The cable that is cut is not necessary for using this battery. It only communicated to a computer program. It's just an RJ connection. The BMS inside works like normal and most customers never use that cable anyway. You can save some money buying these with the cut cable and it'll work the same.

If you want to series connect them you should charge each module fully then connect in series. You can also parallel them. These are one of the most trusted and best built batteries on the market. They are used in many hospitals. Bolts are also included.

You can series up to 4 to make 48v modules.
