Review on 🔋 High-quality DROK 090551 Red LED Panel Display Digital Voltmeter for Automotive Battery Monitoring and Voltage Measurement by Bryan Crayton

(yet). I cheated and just connected the red and white wires together since I only need to control the voltage when it's there. The display doesn't always have to be on. Measured within 0.1 volts by a pair of multimeters I have, so it's pretty close. The "customize" on the back didn't seem to work and I didn't want to mess it up by scrolling. Pretty good, reasonable price. But dude, is it about an inch wide and a half inch high? Tiny. Although perfect if you want it.
