I consider the arguments about 18V 20 to be moot. Its like saying a car
battery is 12V. I have a 36V LiFPo for the trolling motor on one of my
boats, but its actually well over 40 static charge.
As long as the voltage is close its really AH and CA that matter.
Yes, I am aware CA may not be a precise term in all applications, but
its close enough.
