I know, a full battery reads 12.8 open circuit but ...

Ok, there are graphs galore that show open circuit voltages for condition vs voltage. My question is: "What readings do you see on you panel with a moderate load?" Let's say you're boondocking...

our 2 6v batteries are 3 months old (good condition). Under load, at night, they read 12.2-12.5;


And where are you taking the readings? This is important.

Lights: LED lamps take very little power a quarter amp gives a good amount of light. Good old hot wire lamps. a 1156 draws over 2 full amps.
