Needs BMS - ICCNexergy U1-40 12.8v 38.4ah

This pack in particular had a bad BMS. We took the BMS out and confirmed the cells to be balanced. You can add a 4s lifepo4 BMS up to 50a on this pack for very cheap. These batteries have 18650 lifepo4 cells inside in case you are looking to just recover the cells this would be a great option. Super easy to add a BMS to this one too. The lid just unscrews and you have full access to the main tabs and the balance leads.

Fully charged would be 14.4v. Fully discharged 10v. Perfect for 12v applications. Built in BMS.

Dimensions: 8" wide, 5.25" deep, 7" tall.

Weight: 12 lbs.

Note: the balance wires are there with a 5 wire connector however the groups don't go left to right on the pins. You will need to use your volt meter to determine the main negative and each group of series positive wires. Just remember they don't go left to right like normal. It will just take a few seconds to determine what the balance leads are. Don't assume on this pack and just plug it right into another BMS because there will be some backwards wires.
