Review: Nice unit with extended capabilities. - Nice unit. Has even more features that are not described. Reverse polarity protected. Warns of overvoltage. Reads below 5v and above 15v. Update: First unit died after about 6 months from unknown causes. Second unit is now glitching whenever a solenoid in the truck turns off and the inductive kickback voltage gets into the wiring. The gauge freaks out for about a minute or two and then resumes normal operation sometimes it takes a lot longer. I would assume it's going to die soon and has insufficient voltage Spike protection in the design.
Review: Best bang for your buck Volt meter out there. - Replaced driver information center on a 2011 Focus with these and they worked great. 1st, these were within .1 volts of the readings off a regulated power supply when compared to a Fluke TRUE RMS voltmeter. 2nd, they look great. 3rd, the function is one of the best with the three levels of led color. As long as you're in the green you're good to go. the one downside, but not for me, is they are BRIGHT!!!! if you're trying to keep things low key or have sensitive eyes..... watch out! Otherwise these do as good or better in my opinion than Autometer or StretGlow.

## Questions & Answers

**Q: Does this work with AGM?**
A: It will work with any vehicle.

**Q: Do you need a switch inline to prevent the voltmeter from being constantly on when vehicle not in use?**
A: Yes, need one, usually connected to the car battery, but it is connected indirectly.

**Q: will this go to 16.5 volts ?

Thank You**
A: No it will not. This voltmeter monitors automotive battery voltage and anytime voltage is above 14.7 volts the indicator will blink and a buzzer will sound warning of voltage too high.

**Q: what is the mAmp drain ?**
A: The current drain is not the problem.  The problem is that they are utter junk.  I had 3 sets of these all fail within a short time, in the same manner (died to show a constant 5.5v in a 12v system) - the original set, and two warranty replacement sets.  I finally gave up on them, even as warranty replacements.  Bought replacements from PowerWerx, and they've been going fine for over a year, with no discernible issues.  Slightly more expensive, but you get what you pay for.

### ⭐⭐⭐⭐⭐ Nice battery gauge
*by L***O on August 1, 2024*

This was a purchase that I made for my sump pump dual 100 amp hour battery setup (you might see my other reviews for this setup between the wires crimpers fittings that I used). I am no electronics expert but I did compare this with a multimeter reading and they were both close enough.
