Brammo 44.4v 200ah 8.88kWh Module - $100/kWh

These modules came out of huge industrial cabinets that were used as backup power for a few years. They have a ton of life left and are all perfectly balanced. Just add a 12s BMS and you're ready to go. These can put out some crazy power. Easily 1000a if you wanted. Easy access to all the busbars for your balance leads.

These modules can actually break down into 6x 4s packs. Each of those 4s packs will be 14.8v 100ah nominal. Fully charged to 16.8v and discharged down to 11.2v. So this is basically 6 sets of 4s 100ah modules. 3 sets are paralleled first. Then those 3 sets are connected in series as you can see in the photos.

This entire module fully charged is 50.4v (4.2v per cell) and discharged down to 33.6v (2.8v per cell).

The module is made up of 240x 3.7v 10ah lithium ion cells in 12s20p configuration.

These are perfect for powerwalls or any applications because they are built to push some serious power. The BMS is one that communicates to a main mother board so you will need to add your own BMS. You have super easy access to everything on this battery so adding a BMS and making your connections is very easy.

This will have to ship freight because it is 145 lbs. We have excellent freight rates which include liftgate and residential service. Or you can pick them up for free from our Bensalem, PA warehouse.

Dimensions are approximately 31" x 10" x 9".
