Having trouble finding a 2-wire battery voltage meter

[mxrdrver]

I don't know why this has to be soo hard. I can not find one anywhere. Can anyone lead me in the right direction? I'm looking for a 2-wire battery voltage indicator meter that I can use in my box mod build. And please no ebay links if possible. I closed my ebay account years ago.

Because you don't measure voltage directly. You measure the current through a known resistance, and extrapolate the voltage.
