New CATL Modules with 20x 3.2v 280ah Prismatic - 17.92kWh - $115-$125/cell
FREE Shipping to the lower 48 states. This includes residential and lift gate service if needed.
These modules are new in the crate, never touched.
100% automotive grade, not reject grade B or A-. These are the batteries that were not rejected by automotive quality control.
Each crate has 2 modules. The only crate that was open was the one we opened for the photos. Each module has 20 cells in series. The cells are CATL 3.2v 280ah prismatic batteries. This is the best of the best. You can buy these genuine 8000-12000 cycle rated cells for less than the cost of the cells companies like this reject.
Each module has 20 cells in series and is 17.92kWh.
1 module price is $2500. That comes out to $125 per 280ah cell. Total of 17.92kWh.
2 modules price is $4800 ($2400 per module). That comes out to $120 per 280ah cell. Total of 35.84kWh.
4 modules price is $9200 ($2300 per module). That comes out to $115 per 280ah cell. Total of 71.68kWh.
If you buy 2 or 4 they will ship in the original unopened crate with all the straps still in place. If you buy 1 we will have to ship them outside of the original crate and we will make sure they get to you safely with the original blue bag wrapped around them.
If you look at the photo of the busbar you will see there is an area where you can cut the busbar in half with a dremel. You can easily convert these into 4s, 8s, 12s, or 16s modules for 12/24/36/48v applications. Carefully cut the busbar in the center, bend the busbar up, drill a hole, and make your connections with a ring terminal, nut, and bolt. The balance leads are already attached. You can easily wire your BMS with the cells still in the enclosure then mount the whole enclosure on a wall or rack.
Module dimensions are 36" x 17" x 9". These would fit in a proper depth 17" wide rack mount. Module weight is approximately 320 lbs.
The entire unopened wooden crate with 2 modules inside weighs 715 lbs and the dimensions are 52" x 42" x 16".
All of these modules were overstock from a mobile application and never used. They discontinued the vehicle they were made for and the company no longer needs them. We are selling them to you for your DIY projects at a fraction of the price.
There is a quality control stamp on every module. No shady scratched off codes. This is the real deal. These modules will last a very long time.
These are CATL CB2W0 cells. Specs are in the 2nd photo.
Please refer to the photos for more details. The lid snaps off easily and you have full access to all busbars and balance leads. This is the easiest EV style battery to work on.
If you have a large battery project in mind this is by far the greatest option to get never used automotive grade batteries. Your battery project will last a very long time. The busbars are laser welded but there is enough length between the cells to make a hole and a standard ring terminal connection. Laser weld cell connections are the best and most secure.
If you have an EV conversion project you can series 5 for a 320v 89.6kWh module or 6 for 384v 107.52kWh modules. All cells are resting at nominal voltage near 3.24v per cell.
In addition to the cell value there is a lot of other components, busbars, and enclosure value here. Each cell charges up to 3.65v and down to 2.5v.
You don't need to use the main connectors because you have direct access to the busbars but if you wanted to try and find the connections here is the info on the male connectors at the outside of the unit for main + and -. We couldn't find the parts online so we recommend to just make your connections using a nut and bolt with ring terminal inside.
We recommend to keep these in the module. It is not easy getting the cells out without proper tooling. If you want just the cells we are adding them every day, if they are sold out we will add more the next day. They are just selling faster than we can break them down at the moment and the difficulty level is pretty high to get them out.
The video below shows how we remove the end plate. Once the straps have been removed around the cells the end plate will still be hard to remove. You need some leverage to pry that off. As you can see in the video we removed the bolts then left them in as a post to pry with leverage using a pry bar and a chain.
This next video shows how we remove the cells. You can see we already cut the busbars and the plastic between the cells with a dremel and cutting wheel. This must be done carefully without hitting any of the cells. Next we used a plastic pry tool to lift the busbar to make space for the strap. Once the strap was placed around the top of the cell we used a pry bar as leverage to pry the cell outwards. Once it pops you want someone there to catch it before it falls. The cells are not easy to get out with just human strength. You need leverage. Do not use the cells as the leverage base to pry against. The lower your strap is on the pry bar the better leverage you will have. Of course, do this at your own risk. We recommend to keep the cells in the original holders and just make the changes to the busbars.
