When adding a 2nd battery to your vehicle, it's imperative to monitor the voltage of each battery to ensure they are charging correctly. This Battery Voltage Monitor has a backlit LCD Screen making it easy to see, displays both batteries at the same time, and is reversible so that the display can be turned upside down for mounting purposes, if desired.
