🔋 DC Voltage Gauge Digital Display with Touch Switch - Ideal Volt Meter for Boat Marine Vehicle Motorcycle Truck ATV UTV (Blue Light) Review

I have 3 of these that I use to monitor 3 different battery systems in my RV. I like that I can turn them off to avoid unnecessary battery drain. The voltage seems accurate enough, the only reason I give 4 stars is because the battery percentage is off at least on my flooded batteries. I don't really need a percentage so this works fine for me.

Great mod for my RV to detect battery voltage more accurately. You can switch between voltage and battery percentage, or turn it off to reduce battery drain during storage. The gauge wasn't deep enough to fit in a piece of 3/4" chipboard, so I drilled a hole and glued it to a bezel I bought separately. It looks factory installed and works fine

They work great! I use them to monitor 2 sets of solar panels running at around 18vdc with a 12-14vdc load depending on the sun. They turn on at about 5VDC. And at the push of a button you can see the percentage of power the panels are putting out, these are 12V DC panels, very accurately. I hope they keep working, we'll see in time. So far very happy with them.

Just like heads up. It's a tiny caliber. As mentioned (somewhere) in the ad, the gauge hole is 29mm. It's 1.25 inches. I never installed it but I think it would work fine. But I had a 2 inch LED display showing battery life and intended to replace it with a digital display. Guilty. I was wrong in assuming this is a 2 inch gauge that will close the hole. no It is approximately 1.5 inches top to bottom and 2.25 inches wide.

I wanted a simple battery voltage meter for our popup camper and this little guy was perfect for all the needs. I drilled a 1 1/4" hole in the chipboard next to the power converter and then used a couple of taps to splice the stranded white and black wires. The voltmeter comes with spade terminals perfect for the 14 gauge I use. are wire.After installing the cylinder in the chipboard I drilled two pilot holes for the faceplate and secured them with the screws provided.Overall the installation…

Very easy to install and easy to use. The voltage readings are normal, I checked it with a voltmeter. I also like the on/off option. However, the battery percentage (%) is far from accurate. When the voltage is 12.7V, the percentage display shows 76%. A 12 volt system will charge 100% at 12.7+ volts. This is probably because this unit is rated for 48v and there is no way to set it up for a 12v system, the charge percentage is disabled. Since I'm only interested in the voltage value, the…

These little voltmeters were just what I needed for my specific purpose. I use them to monitor the battery voltage of very small DC lights (RV-LED) and 12V battery powered fans (O 2 Cool). This is the case in the event of a power failure. If you lower the battery voltage too much, it won't hold the charge. The meters are connected in parallel to a battery-powered circuit. My wife and I each have one of these and I can charge our phones as well. And with the cigarette lighter socket, I can also…
