Loose nickel connections - K2 12.8v 138.53ah 1789wh Lifepo4 Module

These modules in particular had a spotwelding error on the one outside nickel connection that you see in the photo, therefore the cells have never been cycled. It is possible you could spotweld the nickel back in place but at the very least you can salvage 144 3800mah cells for less than $1.40/cell plus you get the aluminum holders, nickel, and copper.

This module is made of 4s36p K2 3800mah 26650 cells. That is 144 cells already assembled with the custom busbars. New this module is 136.8ah 1751wh.

We also cover the $37 hazmat fee plus the UN-4G packaging which is necessary to legally ship any battery above 300wh. We are licensed and certified to ship fully regulated hazmat.

Weight of the module is 42 lbs

Dimensions:  11.5 x 4.5 x 12
