Battery Voltage Monitor
Built this little battery monitor a while back. I picked up the readout at a flea market for $4 and mounted it in a small box. The switch on the side turns the display on/off. Sure makes for a quick ...

If I see the battery within .1 of the known voltage I would charge one additional hour and be done. My watch is analog with no second hand.... An hour might be 50 minutes or 70.

I just want to see voltage above 14 at some point in the day. 14.1 or 14.111 does not matter to me.
Even if I had a generator with me I don't see the need for more than one digit.
I'm sure you would agree though, there can be a noticeable difference between charging at 14.1 vabs and 14.19 vabs, especially when running a generator?
And yes, there is little difference between 14.1v and 14.111v, while charging, but there is a significant difference between 12.1v and 12.19v when considering soc. All I'm trying to point out is there are much better alternatives to using a 'single decimal place' volt meter for monitoring battery soc.
More data is not necessarily more information.
There is a place for additional accuracy and I don't see it for managing an RV battery.
