Used 25.6V 20Ah 512Wh LiFePO4 Battery Pack with BMS

These batteries can be series connected into 48v. Awesome value here with a nice, compact design.

They were recovered in working condition, are perfectly balanced, and a BMS already installed. They are plug and play.

Bolts are included. Under the red and black circle covers are a standard threaded post for bolted connections.

Specs are in the 2nd photo. They have a BMS already built in.
