Lithium battery display battery parameters: (the following data are reference values, there will be a 2% error range, do not shoot if high accuracy is required)

Reminder: 3.7V lithium battery uses 1 red power indicator and 4 green battery indicators (other voltage ranges are 1 red power indicator and 4 blue battery indicators)
(Note: N is the number of battery cells)
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
