Checking Battery Voltage Seen by RPi? Using HoolyHoo Script

After finishing my build a couple months ago, I noticed that my battery monitor icon never seems to change from full, even when I let the battery totally run down. On the test bench, everything worked great, but I was grounding out the test pin on the Arduino. When I did that, the screen went right to the warning and began the shutdown.

I backtracked through all the connections and everything is soldered correctly.

Is there a way to SSH into the Pi and monitor what voltage is being sent to it?

Hope this question makes sense!

Components I am using are:
Arduino Pro Micro (monitoring battery voltage and interface with GPIO pins)
Generic power supply module
Targus hub
Custom shutdown switch

Change debug to 1 in the script and it should display the read voltage in a terminal window.
