DC 12V 24V Car Voltmeter LED Digital Display Voltmeter Panel, Waterproof Digital Round Panel Voltage Tester Gauge Meter with Terminals for Boat Marine Vehicle Motorcycle Truck ATV UTV (Blue Light)

Works as it should works for 20 volt applications. Adjustable display fast shipping

Good item

I added this to my Ham Radio Station for continuous Battery Bank readout.

Great little dedicated volt meter, but it is consistently 0.2 volt low in readings for 13.5 volts compared with 3 digital multimeters which all read to within 0.003 volts of each other. 0.2 volts means the difference between 90% (13.3 volts) and 100% (13.5 volts) for a LiFePO4 battery; but it still gives a good approximate for everyday purposes.

Fast delivery and simple installation I recommend

I first bought the blue color. Couldn't see it in daylight. I tried again... green... much better, decent even in daylight.

Installed meter on my generator to check voltage on battery. Generac did not come with a way to know if the battery is low or dead. Installed an off/on switch and wired to gauge. User friendly now that I can see voltage with a flip of a switch & recharge the battery before it’s to late when power is out. Slim thickness and can be installed with or w/o the bezel in a small space. Gauge reads correctly with my multimeter equipment. Am happy with install and the convenience this gauge has provided.

i used these to monitor a battery in a back up box and i n radios i build. i could not be happier. just take a dill and punch a hole instill hook up two wires and done. the light is not bright as to blind you at night.

Worked great for my application

It was of small size just what I needed to fit in space I had looks decent quality

I ordered these to install on our pop up North Star camper. As these campers do not come with a battery monitoring station like a lot of them do now, I want to know what my battery voltage is at any given time. So because it’s waterproof, I decided to install the gauge on the battery compartment outside door for convenience and easy of visual monitoring at any time during the day. I made the connection from the gauge to the battery with small terminal camps as shown. The red LED panel is easy to see. Accuracy is very close to my voltage meter. I would recommend this product, and would buy again should the need arise.

One is now installed on my Snow Blower so that I can turn the switch and see if the battery for the light system needs to be charged. It also shows the power draw on the battery and whether or not I want to turn on both frontal 18v LED Lights and the rear amber marker lights. Being waterproof and robust, I am not concerned about it shorting out from being connected. Easy install for your DIY. I use outdoor connectors for the wiring, so it is protected from disconnection from vibration of the Snowblower as well. Not super bright, but legible enough for my use as it is meant to be a reference point for my power needs. This will allow me to see the battery power visually without having to open the small battery box to manually test the battery.

It was easy to fit and works fine.
