Review on 🔋 DROK-100035 0.36-Inch 5-Digit DC Voltmeter Panel Mount Meter - Range: 0-33.000V, 12V/24V Voltage Monitoring Tester Gauge with Green LED Display and 3 Wire Connection by Bill Martinson

I use it to measure the voltage on a LiFePO4 battery which has a very narrow operating voltage range. I knew I was taking a risk by trying a cheap gauge for this, but the reviews claimed this tension gauge was accurate, so I gave it a try. With today's measurement, it measures just like a known good multimeter, up to 1/1000 volt! My only complaint is that the wire harness is too short for anything but small projects, and the wires are too thin to be easily soldered to a larger gauge. I cheated and just soldered the 16AWG directly to the pins and used hot glue for potting/stress relief. Also: It draws about 9mA of current measured and powered by 25.5V connected to the power supply. Will probably buy again for other projects.
