Usage:

1. Connect the positive and negative terminals of the display board to the positive and negative terminals of the tested battery, gently press the red button with your finger, and the IED 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 3-5 seconds, and it will not consume any power when stationary.

3. With reverse connection function, even if the positive and negative connections are reversed, they will not burn. Just adjust them.

Lithium battery group displays battery parameters: (The following data are reference values, with a 2% error range. Do not take pictures with high requirements)

Warm sound prompt: The 3.7V lithium battery uses 1 red power indicator light and 4 green battery indicator lights (for other voltage ranges, 1 red power indicator light and 4 blue battery indicator lights)

(Note: N represents the number of battery cells)

The power indicator lights are red

Battery voltage greater than N × 3.3V, bright second blue

Battery voltage greater than N × 3.5V, third blue on

Battery voltage greater than N × 3.7V, 4th blue on

Battery voltage greater than N × 3.9V, bright 5th blue

12V lead-acid voltage range: (4 series of lithium iron phosphate batteries can be used)

The power indicator lights are red

The battery voltage is greater than 11.0V, and the second blue light is on

The battery voltage is greater than 11.3V, and the third blue light is on

The battery voltage is greater than 11.6V, and the fourth blue light is on

The battery voltage is greater than 12.9V, and the fifth blue light is on
