Thanks for all the helpful responses everyone!
It sounds like the top hypotheses are;
In case it's helpful/relevant, here's the voltage data from when I initially top-balanced balanced the cells;
Unfortunately, I don't have the data of what the charge current curves for each cell or what charge current I stopped at, but I think I stopped at <0.5a for each cell.
I was trying to target 3.6V/cell, but honestly anywhere in that range would be fine. I'm not trying to eek out every last watt of power, I just want a solid reliable system and a fairly detailed understanding of why it behaves as it does.
It sounds like the top hypotheses are;
- Cells not "perfectly" balanced
- Some sort of terminal connection issue

Are you targeting 3.55V/cell peak voltage?
