Good point, watching for relative differences or any early voltage sag during
high rate discharging is the objective. The E-Meter is my "fuel" indicator.
So I will
scrap the temperature considerations and that will simplify the circuitry for
this
project. Hope some one has a slick idea for packaging 12 LM3914 displays !
