Product Features:
<br />1. It is clear at a glance with dual display of electric quantity and voltage, obviously more intuitively. Upper 8 colorful bar shows the battery power, and the lower voltmeter displays battery voltage. the voltage meter's decimal point automatically shifts thus with higher accuracy.
<br />2. It has a wider using range, and it can be used on such electric equipment as 18650 lithium battery, polymer lithium battery set, lead-acid batteries, electric vehicle batteries, nickel-metal hydride batteries and others.
<br />
<br />Product Description:
<br />1. Usage: Please connect the positive and negative terminals of the display panel to the anode and the cathode of the measured battery, then the digital tube displays the real-time battery power. ( the positive and negative should not be reversed, otherwise it will be damaged )
<br />2. Warm Prompt: These products above the options are divided into several different battery sets, please select the appropriate voltage and the power bar will match. Otherwise it will only display the voltage, and the power bar will not normally display. Blue and red refer to digital tube color of voltage display. And power bars display in 8 levels with 2 bars in red and 6 bars in green.
<br />
<br />Product parameters:
<br />1. Working Current: 5-15ma, the lower the battery voltage is, the lower the current is.
