4 pack GSP 3.2v 50ah 160wh Prismatic Lifepo4

Just $28 per cell. You get 4 cells. These batteries were removed from a compressed, never cycled module and all cells test like new. Since they were removed from a compressed module these cells have a slight swell to them but all test well over 50ah. Every battery is tested and we had the studs laser welded on to make sure you can easily assemble these into packs. It is possible some cells will show a slight swell due to being removed from the module with glue but those cells compress perfectly and also tested full capacity. As you can see in the photos these are all testing on average 51ah and every battery is within 3% of new specs. Since DOT requires batteries to be shipped 30% state of charge or less most of these batteries will be around 2.9v when shipped. We took them off after the discharge test to make sure we can ship these legally without risking the tester to charge above that 30% threshold.
