It can also be used for other power/voltage measurement purposes.
Double display battery + voltage at a glance.
The display is more intuitive.
The upper 8 bars show the battery power (2 red and 6 green).
Downlink voltmeter (display battery voltage), voltmeter decimal point automatic shift accuracy is higher.
It has a wide range of applications, including lithium battery packs, lead-acid batteries, car batteries, electric car batteries, and many other types of batteries and electric equipment.
The calculation of the existing voltage is the same as that of the power display meter of an electric vehicle.
The meter head automatically recognizes the voltage and electricity, and has a reverse connection protection function (reverse connection will not burn).
