My three meter homemade battery monitor has two DC voltmeters (one for each of my two battery banks connections) and a master DC Current meter that shows how much DC current is always being demanded and/or how much DC Current is being put back into the selected batteries when being charged. Of course when both Battery banks are placed in parallel with my Battery switch setup these two DC Voltmeters meters will read the same value like shown here.

Always keeping an eye on this centrally located three meter battery panel lets me pretty much know what is happening to my batteries in my setup.
This DC Voltage and DC Current monitoring concept of never letting my batteries not get below the approximate 50% charge state has keep me going for many years of use.
I can survive drawing continuous 25AMPs of DC Current between 6PM and 11PM each day off-grid and not go below the 12.0VDC level if my batteries have been charged up to their 90% charge state prior to using the batteries.
I hate surprises...
