LED Digital Voltmeter DIY DC 0-40V Voltage Meter Auto Car Motorcycle Voltage Tester Detector - Green

• The range is DC 0-40V, 2-wire access, breaking the conventional voltmeter, is the latest design, can work directly in 5V, 9V, 12V, 24V and other circuits without voltage regulation
• Equipped with two wires, it is convenient to connect to the line inside the car/E-bike/motorcycle. It has the function of reverse connection protection, and the line will not burn if it is reversed. It is used to monitor the battery voltage, grasp the battery voltage status in time, and can also be used for other product voltage measurement purposes
• Good product stability and high measurement accuracy
• Appearance adopts standard size, easy to install
• The power supply adopts polarity protection circuit
