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

I bought this battery gauge for our small camping trailer to monitor the battery level when offline camping. I originally bought a more expensive "top brand" sensor to use, but it wouldn't arrive in time for our trip, so in the meantime I've ordered this one. After some time of use I realize how useful it is. It displays the voltage as well as a percentage based on the voltage number. I verified its accuracy by testing the battery with my digital voltmeter and it was 100% consistent with a tenth of a volt on multiple levels. Colored percent displays also corresponded to the corresponding voltage. When my more expensive sensor arrived I didn't install it as planned because it didn't have percentage displays and I really like that. So this one stays forever!
