Review on 🔋 SUPNOVA Battery Monitor: Versatile Voltage & Capacity Tester with Buzzer Alarm - 12v to 72v Car & Golf Cart Battery Indicator Meter by Dan Davis

I needed this to monitor the battery at my shop which powers some LED lights and is part of my solar array. This is the perfect solution! In addition to the quick display of the battery voltage, I also get a percentage display and a display. Cautious! Being able to customize it for my LiFe battery is a big plus. There are several presets, plus a custom option that lets you adjust the high and low points to get the sensor working properly, and the percentages to suit what you're tracking. You can also set the screen to be on all the time, or turn off and off at a set interval, as well as an under-voltage alarm that you can turn on or off and set its trigger voltage. Not sure what more to expect from such a small device at this price point! lol I drew a simple little bracket in CAD and 3D printed it so I can mount it on the board with my solar charge controller and inverter.
