LG 7s 24v 1.1kWh LITHIUM ION MODULE
These modules came out of the 48 server rack batteries, there are 2 24v modules inside. Outside of the racks we can now ship them ground instead of freight which saves a ton on shipping or pickup for FREE at our Bensalem, PA location. For just $125 you get 1 24v module that tests around 1.1kWh (1100wh).
At this price you can't go wrong. We have cycled and tested every module and every module is balanced. 7s configuration for lithium ion is perfect for powerwalls, golf carts, forklifts, and many different DIY projects. We've conducted real tests on these and on average you can expect around 1-1.2 kWh out of the original 1.6kWh. The modules use 15ah LG cells and they are in 7s4p configuration. I would recommend to limit the continuous discharge rate to around 3c. A good rule of thumb would be 2500w per 24v module. 100a discharge rate per module is perfect.
Each 7s module has plenty of wire length for the balance leads to splice into your BMS wiring harness or you also have access to the bolts on the sides where you can make your connections with ring terminals. These do not come with a BMS so you will have to add your own but these are super easy to work with.
