LOL...I'm tempted, very tempted. We'll still need to do CC testing
just to verify (disprove?) manufacturers AH ratings as a baseline, so
I think I'm still stuck.
Actually, having both numbers...lets say, the results of a 100A CC
single-cell discharge test and 12-milliohm CL test (ignoring
real-world resistances that mess things up) would be interesting.
Or maybe I'm just trying to make the best of my situation...
