Linkstyle 2PCS Battery Meter, Waterproof DC 12V Voltmeter, LED Digital Display Voltage Gauge, Round Voltage Meter for Marine Car Motorcycle Truck Boat RV, Short Body

I picked this up to provide a voltage readout for a vintage Austin Healey. I like the small size and the bright display is a plus, because this car is for top-down driving on sunny days. The included bezel, while decent, didn’t suit my desired mounting location so I fabricated one up. That said, the included hardware is surprisingly good. The positive and negative lead connections are pre-wired and, if appropriate to your mounting location, are simply plug and play. I pictured the positive lead with its included inline glass type fuse holder, although I changed mine out for a blade type fuse.As mentioned, the display is bright and sharp. The individual red, yellow and green lights on the perimeter of the display light up sequentially as voltage increases, which adds to the at-a-glance legibility. A nice touch.In summary, this is a nice, unobtrusive voltage indicator that is easy to install and lends itself to a variety of applications.

Easy to install and worked Well!

Hard to see in bright light, easy to install, us for boat batteries and they don't seem to drain any power.

Perfect

Exactly what I wanted

I purchased a pair of these meters for boat use. One was dead-on within its 0.1V resolution (reference Keysight 34461A bench multimeter), the other was slightly off by about 0.05V. Uses 20mA in operation. Minimum voltage where the display turns on is 5.1V. Maximum voltage before display shows 888 error was 36V (no damage occurred). The entire range between minimum and maximum voltages is just as accurate as the intended mid range. Curved bar graph is mainly for entertainment, though the red zone makes sense for lead-acid (see picture for reality). Red warning LED illuminates at 14.7V. Not going to be easy to read in direct sunlight, but very nice otherwise.

Just received these and tried out one of them to see what they look like lit up. First off, they are smaller than I expected, but no complaints because I did have a concern about battery drain. Dreary afternoon but it lights up brightly and looks good. On a sunny day, with the distance to my seat, we'll see, but I'm not concerned. The numbers might be a bit small, but the dial should show brightly. They look to be well made. The packaging is minimal, but no signs of damage, and given the price, and less waste, well done! I'll definitely update after use if I see any problems. I'm happy!

Very cool and perfect brightness for my needs.
