Here's a down and dirty voltmeter panel made from thin hobby plywood, sprayed heavy with Rust-Oleum Hammered paint, a simple cheap press to actuate switch and a cheap voltmeter from Ebay. Wires connected to a direct battery output source (battery hot side directly). It's just a voltmeter and will indicate battery voltage and whether battery is being charged or not. With the press to test there is no parasitic draw and not affected by battery disconnected or not.

Something called voltage drop esp with low voltage DC circuits can be very important. Longer wire= more resistance, heat and less power available.

The current draw (microamps), and hence voltage drop in the wiring of a voltmeter is meaningless compared to our other 12V accessories.

The leads to my permanently installed Drak digital voltmeter ($8 Amazon) are 20 gauge. I used 14 gauge wire (about 5ft) to connect the voltmeter to the nearest 12 volt source because that's what I had on hand.

The small little voltmeter I bought that has an LED display is around 10mA draw. LOL It could be 100 feet away and it wouldn't matter.
