📟 2PCS Red LED Digital Voltmeter Voltage Meter DC 4.5V to 30V Panel Meter for 6V 12V Electromobile Motorcycle Car - DGZZI Review

Good thing it came in a pack of 2. When I tried to install the first one both wires broke. The 2nd still works, I installed it on the boat's battery box.

Product is ok, works as expected, display is more than bright enough. Mine has started reporting up to 4.2v, your mileage may vary. The module draws less than 20mA compared to what I've seen. I would have liked this product more if it had a potentiometer to adjust the accuracy but it works for my purpose.

Need a small panel mount voltmeter for a project. That's what it's good for. Snaps securely into the cutout in the project box. Large, easy-to-read display, even outdoors in bright daylight. I removed a star because it reads about 0.2 volts (tested with a calibrated Fluke multimeter). It's close enough for my purposes, but I wish they had an adjustable pot like some of the other options.

Installed on my Goldwing 84. Tested before installation, works fine. All segments have been read. I cut a hole in the side cover which I wasn't happy with but expected it to be ok. Carefully assembled, soldered and heated crimps, connected to the fuse terminal, turned on, and some segments were missing.
