Open Lid - 12.8v 32ah 410wh LifePo4 Battery with BMS - $60/kWh

At this price, if you have a need for 12v or 24v batteries, it doesn't make sense to buy any other battery. These batteries we opened the lid to inspect inside for balance and functionality. We have proper tooling so we did not have to cut the lid open. It fits back in place perfectly. The lids on these particular batteries are taped down with strong clear tape but you can always glue the lids down again if you don't like the look of the tape. Otherwise the batteries are fully functional. If you are more interested in recovering the 40x 26650 cells, enclosure, and the BMS then these will save you a lot of time since you can just remove the tape the lid will pop off easily. The battery slides out of the case easily.

We took plenty of photos so you can see what the batteries look like inside the cases. Absolutely beautiful batteries with very high quality construction.

These are plug and play. 12.8v 32ah with 40x 26650 3.2v 3200mah lifepo4 cells in 4s10p configuration with a medical grade, high quality BMS.

We tested every battery under load. Over the years, we capacity tested thousands of these batteries and they averaged around 90% of original capacity. They only get used for 2 years to power medical computer carts in hospitals before getting swapped out so they are very slightly used and have plenty of life left.
