Battery type battery level display, select the corresponding solder on the solder pad to detect the voltage of the battery pack corresponding to 1S-8S
Display battery quantity parameter: (Note: N represents the number of batteries)
1. When the battery voltage exceeds N*3.3V,it will illuminate 1 battery
When the battery voltage exceeds N*3.5V,it will illuminate 2 batteries
3. When the battery voltage exceeds N*3.7V,it will illuminate 3 batteries
4. When the battery voltage exceeds N*3.9V,it will illuminate 4 batteries
When the battery voltage is less than N*3.3V,the four display screens will close, indicating that the battery level is less than 3.3V and needs to be charged.
