12.8v 400ah 5.12kWh Lifepo4 Battery - Needs BMS - Open Lid

Only 1 left in stock at the moment. Unfortunately this battery is too heavy to ship ground and must be shipped freight. If you are buying a lot of batteries it would make sense to add this to your order so we can combine everything on the same pallet and the shipping would make more sense. You can also pick up for free from our Bensalem, PA location.

We opened the lids of the cases to inspect each battery. The 4x 3.2v 400ah cells in series are all perfectly balanced but the BMS is not working. This is an amazing opportunity to save money and add your own BMS units to these. The balance lead wires and main connections are easily accessible. You can also top balance multiple batteries, put them in series (24/36/48v), and add one overall BMS.

You can easily open the lids to access to the wiring and the cells. The lids still fit back on and you could always glue or tape them closed again.

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.
