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. WE HAVE NOT TESTED THESE PACKS SO IT IS POSSIBLE YOU WILL GET A GOOD ONE BUT IN OUR EXPERIENCE WITH THESE MODULES MOST OF THEM HAVE BEEN DISCHARGED SLOWLY FROM THE BMS. IT IS POSSIBLE THE BMS MONITORING DRAINS THE PACKS BUT THESE HAVE NOT BEEN SITTING FOR TOO LONG SO YOU SHOULD HAVE SOME SUCCESS REVIVING THE CELLS. WE ARE SELLING THESE DIRT CHEAP 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 or ANR26650M1-A CELLS! These modules are in 11s1p format so they are set up pretty much for 36v applications. You will have to split the case at the seam and crack open the modules. 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.

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.
