At this price you can't go wrong. We have cycled and tested every module and every module is balanced. 14s configuration for lithium ion is perfect for powerwalls, golf carts, forklifts, and many different DIY projects. Check out the discharge curve in the 2nd photo. These are real tests we've conducted on these and on average you can expect around 2-2.4 kWh out of the original 3.2kWh. The modules use 30ah LG cells. As you can see in the 3rd photo there are actually 2x 24v 7s2p modules wired in series. You can also just remove the modules and use them in a 24v application. The series busbar connection between the modules has a 300a fuse so you know these modules can push some serious power. I would recommend to limit the continuous discharge rate to around 3c. A good rule of thumb would be 2500w per 24v module or 5000w per 48v complete module. 100a discharge rate per module is perfect. If you have a 48v golf cart you can use 2-3 of these in parallel and you'll be able to run that golf cart easily.
You will have to add your own bms but the wiring is easily accessible. Each 7s module has plenty of wire length for the balance leads to splice into your BMS wiring harness. We recommend 100a Daly 14s bms units for these. If you are building a larger powerwall and won't be pushing these hard then a 60a bms would be nice and very inexpensive.
