Hello, I have a drone with APM and power module (from an aliexpress kit), it flies very well and shows battery voltage on my radio by using the flysky telemetry, but I will get the 3dr telemetry soon and will connect it to the mission planner in flight.
So my question is: Does the power module need current calibration? I already calibrated the voltage, but I didn’t find current consumption (amps) calibration in the docs! Is it necessary? And if it is, how to do it without a power clamp meter?
