Sounds reasonable, but surely the charge current is much less than the
discharge, so voltage drop on discharge will triggrer low charge cutoff
for the pack long before this becomes an issue with charging? I have had
problems with high self discharge on headway cells, still within spec of
5% per month, but even at 5% it is enough to cause serious problems when
others are zero, unless it is charged often.
I think it would depend on how close to the normal values the limits are
set. Maybe the over-voltage limit is only 0.1v above the normal
end-of-charge voltage, while the under-voltage limit is 1 volt below the
normal end-of-discharge voltage.
