Capacity Testing and 20 HR Rating
I'm thinking about doing a capacity test on my four GC2's. They have a 20hr rating of 215Ah. One thing I'm curious about is how the 20hr rating would have been determined. Being 6v, would they h...

My little GT power meter I have on my Meanwell counts Watt hours. i have another one I can use on any circuit where I have installed 45 amp power poles, such as to the DC to DC converter powering this laptop.
The voltage drop under load is rather significant on this circuit, and the amp hour figure is likely way off compared to the watt hour figure, in how it relates to AH taken from the house battery.
Too bad my mind was trained with Amp hours instead of watt hours. Relearning will not be easy.
That constant change of voltage under load or charge really throws AH figures out of Whack. Ballpark is mostly fine, but hardly precise.
