The one I've built for my leaf cells will tell you if any cell has gone
under/over. (a single LED for the whole pack)
It does up to 200ma or so of bypass regulation, which seems to be enough to
keep my cells balanced.
If you go overvoltage during charge, it turns on a relay - which I've wired to
the Reg Shutdown line on my PFC charger.
