This Digital LED Voltmeter measures the voltage at a particular point of the system it has been hooked up to and then provides a readout on its three 7-segment LEDs.
This voltmeter is able to provide a readout of voltages from 4.5VDC to 30VDC 

Easy wire connection, just need to connect two wires.
 In order to get the best accuracy, the module will move the decimal position automatically according to different voltage; Will correct to two decimal places when voltage is lower than 10V;
Correct to one decimal place when the voltage is higher than 10V.

Note: Do not use 30V voltmeter for 24V battery, for the left capacity is insufficient for the voltmeter when the battery is fully charged. Moreover, a higher pulse will be produced during charging and working.
