*Troy 12.8v 20ah Lifepo4 Batteries - Needs BMS

These batteries have balanced cells in them but the BMS does not work. We already cut open the plastic cases so we can inspect inside the battery. All cells have good voltage. You can top balance the 4s packs and put them in series into 24v, 36v, 48v, etc then just add one overall BMS if you want.
