James, thanks for the interesting link.
FYI, some of the same figures, in a **much more legible** version, are

Much better mechanical drawings, to be sure.

Another solution (other than simply not discharging the battery to its
limits) is to use a battery voltage equalizer circuit:

They don't tend to be cost effective unless you are using larger higher
power batteries but I just thought the technology might be interesting to
some here.
