12.8v 50ah 640wh Lifepo4 Battery - 4s 12v

These batteries are balanced and every battery we tested was above 50ah. They were overstock from a large project and come with the balance leads. Very easy to add a BMS.

You can series as many of these as you want then you can add a BMS. Before series connecting you should top balance each module first. Each battery comes with 4x 3.2v 50ah lifepo4 batteries in series. They can handle 50a discharge and 25a charge. We are not sure what the brand name of the cell is but they perform great and are very well balanced.

Module fully charged - 14.6v (3.65v/cell)
Module fully discharged - 10v (2.5v/cell)
Main post threads - M6 x 1.0 (bolts not included)

Dimensions: 12.5" x 3" x 5"
