Brand new Smartgauge Battery Monitor. You can check the status of charge (SOC) in easy to read % or voltage of your 12 volt battery bank in RV, Camper, Boat etc. Easy to install.
I got two units directly from UK so I'm selling the second one. In the US they sell for $280 +tax +shipping. Selling this one for $240 shipped (as long as the shipping charge is decent from Canada).

Face Plate = 4 3/8" X 3"
Cut Out = 3 3/4" X 2 1/2"
