⚡️ Waterproof Digital Round Panel Voltmeter – 2 Piece Set for 12V DC Car Voltage | LED Display | Compatible with Vehicle Motorcycle Truck Camper Caravan ATV UTV Car Boat Marine | Red Digital Review

Worked til it rained. Then he gave wrong numbers. Disconnect and reconnect and it worked until the next rain. Then it only showed half the voltage (checked with a voltmeter). I do not recommend.

I connected them to the batteries on the boat. One for the main battery and one for the trolling batteries. They are very bright and easy to read. I am very happy that I can constantly monitor my tension. They work as advertised.

I installed them on all my battery trays so I can check battery health at a glance. You have not worked for more than a year and continue to work normally (always on). I recommend them if you need a voltmeter.

This is a relatively simple device. I wasn't expecting any problems, but to my surprise, right after installing it, I noticed that the numbers were hard to read. Worse, when the sun is shining brightly, you can't read at all.

So I bought these for my service truck so I can easily check my voltage as Ford decided we no longer need voltmeters. Installation was easy. The screen is pushed back a little further than expected, but the function was still checked for accuracy with a voltmeter and it was about 0.2 volts off, so not too bad.

Este producto parecía un accesorio muy sencillo pero a la vez Important donde puedes leer de forma sencilla los valores para estar al tanto del voltaje to auto, pero de tu auto, pero lo maravillo que es lo quita con su fragilidad, de los dos el primero me duró sólo 3 semanas y murió, y el segundo solo uro un día y murió también, no lo recomiendo hasta que no mejoren la calidad del producto para que no se dañe tan quickly.

So I drilled a hole and routed the wires (no going back now) I connected it to the switch so it doesn't work all the time. Anyway, I pulled out my multimeter to see how accurate it was, on the meter it showed 13V, on my multimeter it showed 13.28 (battery voltage) on the source and on the back of the meter itself. Of course ... It's not much different. It connects to the car battery that I use for my trailer tent to turn on the extra lights. I use it to see on the fly if I need to charge the…

I bought these little flow meters to help with my mowing project. A voltmeter that monitors the battery and charging system prevents surprises. The meter was relatively well made, had a very nice display (green) and was easy to install. No initial problems. I've read about possible inaccuracies, but I was looking for 12.0-13.0V DC, so a tenth wasn't a problem. Then both the first and second counters failed after about an hour, I observed the polarity. The problem can be that these gauges cannot

I bought these battery tension units to see if my little solar chargers would keep my rarely used generator battery in good condition. Very bright even in the sun. It only took two wires and I wish it had a fusible link. Now I'm not sure, but this device could probably stay on without being unplugged. However, I install them on a key switch that turns off when the key is turned off. I just turn the key to the "on" position and monitor the battery charge. Installation, well, it's easy if you're…
