These batteries have cells that are perfectly balanced but they need a BMS. We cut each lid open so you have easy access to the cells inside with the balance leads. The most common issue is the BMS bluetooth locked out the BMS on a lot of them. So all 4 cells will be well balanced and have good voltage. Just have to add a BMS. All of these batteries can be series connected into 24v, 36v, or 48v then you can just add 1 overall BMS.

Only a few left in stock.

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.

They were recovered from lightly used larger battery packs. We tested a few random packs and they all tested above 90% capacity. All batteries are checked for good voltage and they are all balanced.

Here are 12v Lifepo4 modules with 8 cells in 4s2p format. Every battery is checked and all cells will be balanced with good voltage. These packs are awesome because they line up nicely next to each other.

These batteries were only used for about a year. They all have good voltage and a 15a rated BMS.

They are made up of 8x 3.2v 6000mah 32650 cells in 8s configuration.

The dimensions are 5 3/8″ x 4 3/8″ x 2 3/4″ and the weight is around 3 lbs.

These batteries were recovered from slightly used modules with laser welded connections. Only a few left at the moment.

At this price, if you are comfortable welding aluminum tabs or have a laser welder this is a great deal. We get asked about being able to tap and die into the studs and the answer is these cells have a tab that is roughly 10mm thick but of course you don’t want to go that deep if you do try that. We obviously can’t recommend doing this but if you want to give it a try at your own risk maybe limit the depth of your thread to 6mm or less.
