51.2v 30ah 1.536kWh Lifepo4 16s Battery - Needs BMS

This battery is balanced and just needs a new BMS. The balance leads are all there which would make it very easy to replace the BMS. The connector is an Anderson connector but you could always just make your connections inside the battery under the lid which is easily accessible by removing a few bolts.

The cells inside are cylindrical.

Weight is 38 pounds and dimensions can be seen in the photo. Roughly 10" x 9" x 8".
