I have the 240 mAh battery connected to my Sodaq One, also the USB is connected. How can I tell if my battery is charging and when my battery is full?
The uint8_t getBatteryVoltage() function of the SodaqOneTracker_v3 project from Github (https://github.com/SodaqMoja/SodaqOne-UniversalTracker-v3) keeps returning around 120 and does not go up while the USB is connected.
When the yellow charge led is on the battery is getting charged.120 * 10 = 1200 + 3000 = 4200 = 4,2Volts = FULL
The battery voltage will be between 3300 and 4200 millivolts.
Does this calculation work for all the different batteries? Or does a 800 mAh need a different calculation?
The calculation is the same for all batteries.
