7.2v 72.8ah 524.16wh 2s28p Lithium Ion Module

Just 1 left at the moment.

These modules were recovered in working condition. We tested a few and they tested around 67ah so they are still over 90% of the original capacity.

All cells have good voltage and are balanced.

There are 18650 cells inside. The orange/white wire is the balance lead connected to the series between cell groups 1 and 2. 7 of these in series would make a perfect 14s 52v battery. 5 in series would make a 10s 36v battery. Of course you should charge each module to 8.4v to top balance before connecting in series and adding a BMS.

Module weight is around 13 lbs.

Dimensions are 10.5" x 8" x 3"

You can make connections with bolts as you can see in the photos. The main positive and negative tabs line up to the threaded hole for the bolts.

There appears to be 56 cells in 2s28p. That's what we could determine based on what we can see. We recommend charge limits of 35a and discharge limits of 70a since we don't know the cells used inside. They are naked cells and these would not be good for cell recovery since it is a custom pack. It appears very well built and likely difficult to recover cells from. The cells are likely 3.6v 2600mah 18650 cells.
