12.8v 34ah 435.2wh LifePo4 Battery with BMS - $64/kWh

At this price, if you have a need for 12v or 24v batteries, it doesn't make sense to buy any other battery. You can parallel connect them into larger battery modules and even series connect them into 24v modules. If you series connect into 24v you should charge all the batteries fully, then connect in series, to achieve a top balance.

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. To be clear, you will receive complete batteries in the cases like you see in the 1st photo. We just wanted to add more photos so you can see what the inside looks like.

These are plug and play. 12.8v 34ah with 40x 26650 3.2v 3400mah 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 often only get used for 2 years to power medical computer carts before getting swapped out so they are very slightly used and have plenty of life left.

Specs show max charge and discharge current of 32a.

At just 10 pounds these are perfect to take on the go, use for power chairs, camping, RV, and especially solar storage. Can be series connected up to 24v. It is unknown if they can be series connected into 36v or 48v.
