Review on ⚡️ DROK DC 4.5-100V LED Voltage Current Display - Digital Voltmeter Ammeter Multimeter Panel for Automotive Motor Battery - 0-50A Volt Tester Meter Amp Detector - Voltage Amperage Monitor Gauge by Len Chandler

Please see my edit below :) I just received this today. First test I do: - I'm using a 9V power supply (green [-] and yellow [+] wires in the lower right corner of the picture) - all the wires are done (color coded for a better view). ) - all cables were checked for continuity - the motor turns - the multimeter shows that there is 9V, the article says to contact them, but I still don't understand how I feel. Perhaps the motor consumes almost no current, what shows nothing?there are no amplifiers on the display itself. The voltmeter shows 42V, but one of them charges the batteries if they fell off, of course. Get the maximum consumption of 44 amps! So this thing is great! Just use it for high amps, not low amps. :) I highly recommend it!
