  Yes, I did this 15 years ago with the Dewalt A123 cells. Usually only one cell had failed. Betty you could still do the same.

    police auctions of confiscated scooters, ones that folk abandon on the wrong place and get impounded are a great source of cells. hit up the homebrew powerwall forums for more sources.
