I want to install a 12V digital volt meter
I wanted to install a digital LCD volt meter with LED backlight display that I bought off amazon. I'm familiar and comfortable with 12V electrical and I have decided to just tie into a 12V connection...

I don't think an analog voltmeter is what you want for battery monitoring. You are really looking for voltage changes in the 12.0 to 14v range. A tenth of a volt is important. That may be hard to see on an analog meter.
I know some people use them but IMHO, a digital meter is better for this task.
If you want an analog meter, you can always hook up a 5V meter in series with a 10V zener diode or some more sophisticated voltage reference and create a 10-15V analog meter to get better precision in the readings. The meter scale would have to be recalibrated and redrawn, of course.
