I doubt they would be. Even laptop battery BMS systems brick themselves so they can't be reused. It's where I get all my 18650's from. They are all NOS batterie

I doubt they would be. Even laptop battery BMS systems brick themselves so they can't be reused. It's where I get all my 18650's from. They are all NOS batteries that were never used and the BMS disconnected the cells due to fractionally too low voltage. Cells are fine but the BMS chip will never work again.
