You can track cell balance on PC, using simple hardware adapter which is not yet published on my site (it will be published soon).
You can track cell balance on central module with the display, or even (with bluetooth adapter and simple interface) on smart phone... Problem is that I am not skilled in programming Android applications and don't have time for developing such applications. However, I'm seeking for partner who can do this job, as well as I'll need somebody to make Linux application too...
If you are not so much interested which cells are charging slower and if information about balance status of whole battery is good enough (three statuses: no cell bleeding, some cells bleeding and all cell bleeding) then simplest central module is enough. Simplest central module is good enough for complete protection of the battery...
Doesn't need app or anything, not even trackinh while charging.
The best indicator of cells healthyness are "sag" discrepancy on discharge. If a small set of cells are sagging much more than the rest, its an indicator of future problem and the cells need to be changed.
My ncr18650pf cells haven't been balanced after a year of use. But I carefully check cells sagginess on discharge and had to remove 1 string of cell to keep the pack safe.
