Description:
Digital display shows voltage and quantity of electricity
Universal fit for various models of motorcycle, electric vehicles(6-100V), can be automatically identified, real-time display
18650 lithium polymer lithium battery, lead-acid batteries, electric vehicle batteries, nickel-hydrogen batteries and other types of electric equipment can be used
Use of digital display voltage, you can directly know the battery power and monitor the remaining battery power according to your own electric vehicle battery voltage, you can also judge whether the battery is damaged by full charge battery voltage

Installation Instruction:
Red is the power of the positive line, black is the negative
Put the display board positive and negative wire terminals to connect the two-side of measured battery positive and negative, then it will shows real-time battery power

Fitmnet:
Universal fit for electric scooter, motorcycle and so on

Note:
1.No English installation manual, professional installation is highly recommended
2.Please select the appropriate voltage so that power bar can match it, otherwise voltmeter can only display the voltage and power bar will not normally display
3.Positive and negative do not reverse, otherwise it wil get damage

Package Included:
1 X Voltmeter
