Also, if you remove the end you can simultaneously recondition 10 pairs of sticks by using 10 chargers. (or maybe that's 9 pairs + 2 sticks)
What about modifying the end so that the sticks are not attached in series and then add a second, removeable plate over it that connects them in series? This way the PTC strips would stay connected.

They charge/discharge circuits are/can be electrically seperated by the relays.
You want to avoid taking the ends off IMHO. It's a right pain, time consuming and easy to damage the ptc ends especially if the process needs doing every couple of years to keep an old pack in shape.
I think it's best to do the sticks individually or you can't isolate a bad subpack without doing further work. This system will show up bad subpacks without extra work. I want it super simple to connect and operate.
Remove pack from car, take off the relay board, attach the magnetic connector boards and press the go button! Come back in a week with it all done for you and a nice text file for the pc detailing the data pack/performance.
I don't know about your experience but are there actually many bad subpacks (dead cells etc) or is it just they have gone out of balance.
In the two packs I have seen done, one had a bad subpack and the other was ok after rebalancing and a few decent cycles.
I've got a couple of spare packs which I can test all this on, and I can keep a rebalanced one in stock and swap them out for people in trouble and then do their pack at my leisure and pass that on to the next person.
