Put a 7824 for the meter, should take care of the supply, provided it has separate power and input lines.
You can calculate and select the component values for a 30 volt circuit.
Another option, is to use only one cell of the battery as reference, and use a common battery charging IC to control the charging cycle. For example TP4056, maybe you can use something like that.

I appreciate the input. I already have an external smart charger. What I need is some indication of battery level, even basic LEDs would suffice--just something to prevent me from dropping below 20v. A full fledged display is fine, but that might be more elaborate than necessary when considering my total lack of skills and knowledge... anything that I do, I pretty much need a schematic for.
Can you cut a 58mm x 28mm opening on the sure front plate to insert this meter in it?

There's already a hole for the Sure display (ME-DV42331) measuring 3.11" (79 mm) W x 1.65" (42 mm) H x 0.98" (25 mm) D. I will not make any more alterations to the chassis.
I could take the guts out of that 36v model you linked and put it into the Sure housing, but the power button would be an issue. Technically, that is what I was planning on doing with a DIY meter--slapping a new breadboard inside the Sure housing.
The easiest thing would be for me to make one of the designs in the video that I posted, just using a design that allows for more than 30v.
How about this one
