Used 50a 4s 12v Lifepo4 BMS

These were recovered from 4s 12v lifepo4 batteries that had a bad cell. We recovered the BMS units out of them and are offering them for sale at a very low price.

There are 2 different kinds of BMS, if you order more than one, we will send a similar BMS.

These BMS units were recovered in fully working condition from decommissioned battery packs. Balance leads remain intact and connected – ready for immediate reuse or testing. Clean, functional, and pulled from operational batteries.
