Product Features

• This voltmeter has a volume of 0.36 inches and a range of DC 0-40V. It is connected with 2 wires and breaks away from conventional voltmeters. It is the latest design and can work directly in circuits such as 5V, 9V, 12V, 24V, etc. without the need for voltage stabilization. Equipped with two wires, it is convenient to connect to the wiring inside cars/electric scooters/motorcycles, and has reverse connection protection function. The wires will not burn when connected in reverse. Used to monitor battery voltage, timely grasp battery voltage status, and can also be used for voltage measurement of other products. Note that the maximum input voltage for 2-wire use should not exceed 40V, otherwise there is a risk of burning out.

• Note: The voltage used should be within 40V (many peers can only be within 30V)

• Ultra low starting voltage, with a minimum of 2.5V for red, 2.7V for green, and 3.0V for blue. If conditions permit, it is recommended to use a voltage range of DC4V-30V for optimal performance

• Good product stability and high measurement accuracy

• The appearance adopts standard push size, easy to install

• The power supply adopts polarity protection circuit
