1: Connect the positive and negative terminals of the display board in parallel to the positive and negative terminals of the tested battery. Gently press the red button with your finger, and the LED light will light up to display the real-time battery level

2: Release your finger, the LED light will go out after a delay of 3-10 seconds, and it will not consume any power in static state.

3: Equipped with board connection function, even if the positive and negative connections are reversed, they will not burn, and can be adjusted accordingly.

 

 

 

The 3.7V lithium battery uses one red power indicator light, four green battery indicator lights, and one red power indicator light for other voltage ranges. It's a green battery indicator light

The first power indicator is red

When the battery voltage is greater than N×3.3V, the second blue light is on

When the battery voltage is greater than N×3.5V, the third blue light is on

When the battery voltage is greater than N×3.7V, the fourth blue light is on

When the battery voltage is greater than N×3.9V, the fifth blue light is on
