Review on 🔋 Waterproof LED Digital Display Voltmeter Battery Monitor for Car Motorcycle Truck Boat Marine - TurnRaise 12V by Scott Richardson

Purchased to install my Weekend Warrior's electrical control box in my range hood. Fits absolutely great. The 1 1/8" hole saw was the ticket (which I already had). There is an instant "monitor" switch which when pressed shows the level of the electrical system and when connected to it it just glows up when I want it. The display is great! My 4 x 6v batteries read 13.56 volts with a multimeter and the meter showed 13.5 volts - great! Much better than 4 nasty bars for battery status!
