4 pack! K2 3.2v 90ah K2B3V90EG Lifepo4 Power module - ONE BAD CELL - Shelf J1
This particular pack has 4 cells glued together for a 12v module but one cell is 0v. So you get 3 good cells in this pack out of the 4 for just $80 each on the good cells. Bolts are included. Just add busbars. This is an engineering sample, the batteries are balanced and all sitting at 3.32V except for the one bad cell.
If you are a car audio enthusiast you may recognize these batteries from a popular brand. These cost almost $400 per battery from them, but we have some for just $80 per battery. These are one of the best Lifepo4 batteries out there and they are trusted by the US military. We include the bolts too. Check out the amazing specs in the 2nd photo. These batteries can discharge at 300 amps continuous and pulse at 700 amps. For car audio these are probably one of the best lifepo4 options. I wish we had more.
