It’s cool.
This dual voltage monitor is installed in my dual battery 2000 Silverado.
Everything went smoothly except that the LED lights are too bright at night.

Added a backup battery to the boat. I required a little indicator because there wasn’t much room on the instrument panel. This is a good fit and function. Because the higher powers the lights, connect the main battery to it (turning off the key) and the aux battery to the second battery. This manner, the dual battery gauge won’t always be illuminated.

Installing this dual volt gauge was simple and it functions flawlessly. Although I’m not sure how precise it is, it does match the Polaris RZR 1000’s readout. The LED flicker rate is my only complaint, and it can be a little annoying at night.

Always know what your batteries look like before you head off shore

So far so good
I implemented it in my fishing boat to assess voltage of starter battery.
So far, everything is going fine. When compared to a manual voltmeter, the measurement is precise. The screen is too bright and difficult to read, but it does the job.

Both wiring and reading this are simple tasks. It monitors the primary and supplemental batteries on my Honda Pioneer. I would recommend it to the group.
Rhoniel Stone –
My truck Ford F250 has a dual battery setup, so I have to double-check the battery each time I turn it on. This is a great fit, but it has a strange 10-second “boot up” phase. Although it changes just every few seconds, which is not terrible, some people could find it perplexing.
Installing was not too long. Make sure it fits snugly by drilling a hole and then filing it out. I have it on a temporary switch.
John Fraiser –
Install this on my Land Rover’s dual battery setup. It remains in operation for a few months now with no problems.
Steve Lakewalker –
Excellent product. This is a highly effective and useful addition to my front center console, which I added. Definitely worth it
Nick Thomas –
The dual battery voltage gauge has an excellent refresh rate and is reliable. The only drawback is that in direct sunlight, it can be challenging to read the numerals.
Amanda Dude –
Excellent performance on the dual battery Honda Pioneer 1000-5 system! Both this device and the Nilight switch panel come highly recommended.

Super simple to setup. I’m using it to keep an eye on my Land Cruiser’s two batteries. The only thing that bothers me is how bright it is. At night, this dual battery gauge completely illuminates my face.

Although I can’t attest to its accuracy, the installation was quick and easy. When it’s extremely dark outside, it gets a little bright, but then, most of them do. In order to prevent the primary battery from running out, I upgraded my Honda Pioneer 1000-5 SXS with a the smart battery isolator and an additional auxiliary battery. The AUX battery powers all of my accessories, leaving the OEM main battery to handle solely the DCT transmission’s startup and operation. I can make sure both batteries are getting charged and working properly with this dual battery volt meter.
