KeeYees 0.28 Inch Two Wires Mini Digital Voltmeter Panel DC 2.5V-30V Voltage Tester Meter LED Display (4 Colors)

KeeYees 0.28 Inch Two Wires Mini Digital Voltmeter Panel DC 2.5V-30V Voltage Tester Meter LED Display (4 Colors)

The voltmeter can be used to measure the voltage of 18650 batteries, mobile lithium batteries, nickel-metal hydride batteries and other battery packs, as well as the voltage of motorcycles, automobiles and other batteries, and can also be used for other voltage measurement purposes. This package include 4 colours Mini Digital DC Voltmeter: Red (2.5V - 30V),Yellow (2.6V - 30V), Green (2.6V - 30V), Blue (3.2V - 30V) Equipped with two wires, convenient and simple wire connection, easy connected to the car / battery car / motorcycle car line With reverse polarity protection, the wire will not be burned when the connection is reverse. The resolution is 0.01V when measuring the voltage below 10V; resolution is 0.1V for voltage above 10V. That can take care of the need for measurement accuracy, but also take care of the need to measure higher voltages. Specification:
Working voltage: DC2.4 ~ 40V
Detection voltage: DC2.4 ~ 30V
Working current:
