* discharged * A123 MODULE w/ 11 26650 ANR26650M1-B - Shelf H1
This module comes exactly as shown.
THESE MODULES IN PARTICULAR LIKELY HAD A FAULTY BMS WHICH CAUSED THE BATTERIES TO BE DRAINED. MOST OF THE ROWS WILL BE 0V, HOWEVER, WE SLOWLY CHARGED AND CYCLED A FEW OF THESE PACKS AND WERE ABLE TO RECOVER A LOT OF CELLS, THESE PACKS HAVE NOT BEEN SITTING AT 0V FOR VERY LONG SO THERE SHOULD NOT BE TOO MUCH DEGRADATION ON THE CELLS FROM SITTING AT 0V FOR VERY LONG. WE ARE SELLING THESE DIRT CHEAP AT JUST 35 CENTS PER CELL FOR THE ABSOLUTELY BEST LIFEPO4 CELL ON THE MARKET. EVEN IF YOU RECOVER 50% OF THE CELLS IT IS WORTH IT BUT CUSTOMERS HAVE REPORTED THAT THEY ARE ABLE TO GET MOST CELLS TO RECHARGE AND AFTER SOME CYCLES THEY WAKE UP AND WORK GREAT. THESE PACKS ARE BEING SOLD AS IS AND PRICED ACCORDINGLY.
MODULES WITH 11X A123 26650 ANR26650M1-B CELLS! These modules are in 11s1p format so they are set up pretty much for 36v applications. Also these are good for salvaging gold from the BMS, typically medical batteries like these use more gold plating than other industry BMS modules. Also great to reuse the cell holders if you want to build these cells into other modules. Just remember to slowly charge them from 0v then when they reach 2.5v you can charge like normal up to 3.65v.
We don't know anything about the BMS and it is likely proprietary, but maybe you can get it to work again. Don't expect to be able to reuse the BMS, this is basically just to salvage cells from these packs. You get 11 m1b A123 cells for just $3.85
THIS IS ONE OF OUR POP UP DEALS THAT WE HAVE LIMITED QUANTITY OF BUT WE NEED TO CLEAR SOME SPACE HERE IN THE WAREHOUSE AND YOU ALL NEED SOME GREAT DEALS!
CHECK OUT THE AWESOME SPECS OF THE CELLS. THIS IS THE BEST A123 LIFEPO4 CELL ON THE MARKET AND THE NEWEST VERSION. These are not the older m1a version cells.
