24v 6.5ah 163.8wh with BMS Li-ion 7s1p - $91/kWh

These are mobility packs that are used but fully functional. Each battery is made of 7 26650 6500mah cells in 7s1p configuration. There is a BMS and also you have access to a charge and discharge port. The discharge port you can see in the 2nd photo. You can solder your wires right to those terminals.

We check every pack to make sure it takes a charge and has good voltage.

The modules are easy to open too so if you just want to recover the cells and build your own pack you can probably sell the BMS on eBay for $15 or so. Just a great value here for ready to use packs.

Each module is 3.75 lbs and dimensions are 6.75" x 13" x 1.5".

The BMS appears to be a 10a rated BMS which is perfect for most applications. At this price you can build a nice size pack that will last a long time. You can always upgrade the BMS if you want but this size BMS is perfect for most applications.

Fully charged voltage is 29.4v
Fully discharged voltage is 19.6v
