Instructions:
Connect the positive and negative terminals of the display board and connect them to the positive and negative terminals of the tested battery. The digital display shows the real-time battery power.
Power parameters:
1S lithium battery, full charge 4.2V
2S lithium battery, full charge 8.4V
3S lithium battery, full charge 12.6V
4S lithium battery, full charge 16.8V
Battery voltage is greater than N X 3.3V, light 1 grid power
Battery voltage is greater than N X 3.5V, light 2 grid power
Battery voltage is greater than N X 3.7V, light 3 grid power
Battery voltage is greater than N X 3.9V, light 4 grid power
The battery voltage is less than N X 3.3V, the power indicator is all off, indicating that the battery is lower than 3.3V, the battery needs to be charged.(N is for the number of battery cells)
Note:
The above data is a reference value, there will be about 2% error range.
Package included:
1 X 1S / 2S / 3S / 4S lithium battery pack power indicator board
