Time to get serious about determining what actually fails in the sticks
Getting ready to start testing

Since Hybrid battery repair has abandoned the pursuit of cell level rebuilding of the subpacks, and I have already built the welder, and other fixtures and test systems,that he does not want, I will use the equipment to dig deeper into determining how the subpacks look at the cell level.

A look at the traces below will show that many subpacks only have one cell that is a bad actor, others show overall deterioration that may or may not respond to charging.
Time to pin down some of the failure modes, and with the new smart chargers, we should be able to troubleshoot a problem pack and determine which sticks are acting up, and then which cells within the sticks require replacement to get the pack back into a useable condition for the least cost.
I grabbed all of the packs and sticks I have, and have assembled them so I can begin the testing.
The automatic whole pack discharger is working well with the 6 100W bulbs, so I will run capacity recovery test on all the packs I have available to see what we see.
