Built-in CURRENT METER
You could get a more accurate current value without using the virtual current meter. In order to use this current sensor hardware, some configurations in Betaflight GUI are needed. In the "Power & Battery" tab:
Note: You may need to slightly adjust offset at Amperage Meter after connecting electronic components, such as VTX, camera, and motor.
Then when flying, you could find the real current value from the OSD information. Of course, the current sensor is configured well in the factory and you do not need to change it as usual.
