48v 6.4ah 307.84wh Battery with Panasonic Cells + 15a BMS

We will be adding these daily. We can only install so many BMS units each day so at the moment they are selling faster than we can make them. We will add more each day as they are completed.

These modules already have a 15a BMS installed. Each 48v module is good for up to 500w of power. As you can see in the 2nd photo the bolt with the blue wire is your negative and the bolt on the left is your main positive. We dress up the balance leads nicely for you. You can parallel as many of these as you want to build a nice, modular 48v battery. Just make sure all the batteries are the same voltage before connecting in parallel and also when you parallel them, use equal length wires from each module into a distribution busbar to ensure even distribution of current to each module.

They come with Panasonic cells inside. 48.1v 6.4ah 307.84wh. You will not find a better deal on 48v batteries with a BMS that have either never cycled or only cycled a few times. Perfect for solar storage as well. These modules have 52 cells inside. Every module tests around full capacity. Since these were used as backup only they likely have never been cycled. The cells are power cells, Sanyo UR18650WX 1600mah cells manufactured by Panasonic which are 25a rated power cells.

The battery module is 8 lbs.

Bolts are included.
