48s2p 153.6v 180ah 27.65kWh Lifepo4 Battery - $72/kWh

There are 4x 12s2p battery modules inside which is perfect for 36v applications. Can be made into 12/24/48v with some busbar reconfiguring.

These are perfectly balanced. They were mounted on EV's that were never used. All cells are resting at nominal voltage and testing above 100% capacity. It is likely these were never cycled but may have been cycled just a few times. Every battery we opened to confirm all cells were perfectly balanced and still at nominal voltage (never charged or discharged). As you can see in the photos the main +/- connectors can be bolted right onto the battery easily. There are already nice busbars connected to them you can reuse for your main connections if you want.

Each battery is made of 96x 3.2v 90ah lifepo4 cells in 48s2p configuration. We are assuming they are EVE 3.2v 90ah cells but they may be Calb or CATL. We added the specs of the EVE cells in the photos. At this price it comes out to just $20.83 per 3.2v 90ah cell or $72/kWh. Plus there is decent aluminum and copper value.

The cells are all laser welded and there is some space on the raised area of the series busbars. You could, at your own risk, carefully cut the series busbars with a dremel and have enough busbar sticking out to make a hole for nut/bolt connections.

We have excellent freight rates so shipping should be reasonable. Or you can pickup from our Bensalem PA location for free.

The aluminum lid comes off easy. There are some standard hex bolts around the edges and the black vinyl on top just pops off for easy access to the busbars.

Each module can make the following:

12x (12v) 4s2p 12.8v 180ah 2.3kWh packs
6x (24v) 8s2p 25.6v 180ah 4.6kWh packs
4x (36v) 12s2p 38.4v 180ah 6.9kWh packs
3x (48v) 16s2p 51.2v 180ah 9.2kWh packs

Each battery has 4x 12s2p 38.4v 180ah 6.91kWh batteries inside. If you upgrade golf cart batteries this is the best deal you will ever find. All you have to do is add a 12s 300a lifepo4 BMS to make a perfect 36v battery for golf carts. All the balance wires are there and the main +/- connections can be bolted.

There is a BMS on here but we don't know anything about it and we recommend to just add your own BMS. I would imagine the majority of our customers will be making these into 3x 16s batteries for 48v systems.

Weight is around 500 lbs.
Dimensions are 42" x 24.5" x 10"

These may be shipped on standard pallets and the blue on the lid is just a shrink coating so they may not have that on there and the whole lid will be a shiny silver aluminum color.
