Review on 📊 High-Quality SMAKN 2-Wire Green LED Panel Digital Display Voltmeter for DC Voltage Range 4.0-30V by Matt Davis

This 12 volt LED voltmeter is a great way to read battery voltage. It doesn't come in a protective case so I made one out of an old metal socket and cap. It took about 10 minutes to cut the hole with a dremel tool. It would have been nice if they included a template for the hole for mounting, but it was an easy job even without a template. The green LED indicator is clearly visible both during the day and in the dark. It also gave very accurate readings (+/- 0.1 volts) without additional calibration. The item arrived on time and in good condition. I highly recommend putting it in some sort of protective case and adding a fuse link on the plus side.
