0v discharged 36 cell A123 module
These are 36 cell battery modules with 36 A123 26650 ANR26650M1B cells. This module was drained down to 0v from the BMS but very likely to recharge. You can cycle the cells a few times and likely salvage some of the cells. They are excellent lifepo4 cells if you can get them to cycle a few times and recover. Some of the modules still have a circuit board on them but these are strictly for recovery of the cell, holders, and nickel.
The module is 12s3p with 12s4p nickel and holders. Each series has a missing cell slot by design.
At 25 cents per cell, minus the value of the cell holders and nickel, even if you only get half of the cells to recover this is still an amazing deal. What other customers have done is slowly charge each cell and cycle them a few times to sort of revive them. These are sold as is.
These are the ANR26650M1B cells from A123.
