4x 12.8v 400ah 5120wh Lifepo4 Battery - Needs BMS - 20.48kWh

We cut open the lids of the cases to inspect the batteries. The cells are all perfectly balanced but the BMS is "off" or locked. This is an amazing opportunity to save money and add your own BMS units to these. If you take 4 of them, top balance them all, put them in series, and add a 16s lifepo4 BMS you will have yourself a 51.2v 400ah 20.48kWh battery for a great price. Also great to make large 12v and 24v batteries. The balance lead wires and main connections are easily accessible.

A few overseas battery manufacturers supply thousands of different private label brands. These have various brand names printed on them but they are all lifepo4 chemistry and structurally similar.

Bolts are included and terminals are inspected.

Fully charged - 14.6v
Fully discharged - 10v
