For those of you that are fortunate to get these cells here is the best way that I have found to salvage them and clean them up.
12 batteries 20 cells each 240 cells.
First thing I do is take a utility knife blade and flick the spot welded tabs on the buss PCB up as best as possible
Then I take a pair of side cutters and pull up on the tabs that I just exposed. Some of them have gooon them some not.
Once you pull the tabs up you have weakenedthe bus bar attachment and you can pop it off with a plastic upholstery tool
The PCB on the end will just pop off
Do 1 side at a time as if you do both you will bend the tabs back in place.
Once you are done removing the buss bars take a #1 phillips screwdriver and remove the 2 hidden screws under the silicone
Then turn the battery around and use the same #1 philips to unscrew the support rod that holds the cells together.
I use a drill and just push in as hard as I can and it will eventually come apart. Practice required
The cells will then separate into individual 4 packs
You can then remove as much of the nickle as you like. I just remove enough to free them from the plastic holder.
Set them aside for final processing.
Final processing with small flush cutters
Final results a nice purple pyramid.
Into the box for testing.
