A Volt meter does not tell you the state of charge of your battery(s)

I used to think the same thing, till I got "GOOD"
Just from my elcheapo volt meters, I know the exact SOC of my batts.
Once you learn/know your system, you can do a lot w/ just a volt meter,.....even an inaccurate one, as long as it is consistent.
But that doesn't mean I don't have ammeters in several places.
All my metrers are LED, and are lit ALL the time. They don't use enuff juice to even think about !
