Issue Summary:
I am building a hexacopter drone using the Cube Orange+ flight controller, Here 3+ GPS, and Pixhawk 2 Mini Power Module Brick. After configuring all necessary parameters through Mission Planner, the voltage readings are showing correctly, but I am facing an issue with the current measurement. The current reading either remains stuck at “00” or doesn’t change at all when I rotate the motors.
Additionally, I’m getting a “Battery Unhealthy” warning in the system, which is concerning, as everything appears to be connected properly, and I’ve confirmed the voltage is accurate.
Additional Information:
When I rotate the motors (either manually or by throttle), the current reading does not change and remains stuck at “00”.
The voltage is being read correctly, but the current measurement does not update, leading me to believe there might be an issue with the power module or its configuration.
The “Battery Unhealthy” warning is showing up, despite the system being powered correctly, which further complicates the issue.
Has anyone experienced a similar issue where the voltage shows correctly, but the current stays at “00” and doesn’t change when the motors are running? Also, if you’ve encountered the “Battery Unhealthy” warning despite proper power connections, any advice on troubleshooting or configuration would be greatly appreciated. Could this be a problem with the power module, wiring, or Mission Planner settings? Any help would be extremely helpful
After your suggestion, I changed the following parameters:
BATT_VOLT_PIN to 14
BATT_CURR_PIN to 15
BATT_FS_CRT_ACT to 1
BATT_FS_LOW_ACT to 2
I also changed the battery monitor sensor type from Other to 3DR 4-in-1 ESC .
Now, the battery voltage is displaying correctly, but the current (amperage) is still not showing.
We conducted our first flight in AltHold mode . The drone was stable with no oscillations, but it drifted in one direction—possibly due to wind—and showed some unwanted yaw motion. We did not get a GPS fix in Loiter mode or Stabilize mode , as observed in Mission Planner.
Additionally, it appears that many parameters and log details are missing , possibly due to incomplete GPS initialization or incorrect logging settings. Please refer to the attached log and guide me with:

I am passionate about building various types of drones and want to work with Mission Planner to bring my projects to life. As an enthusiast, I am eager to learn and apply advanced flight control and automation through Mission Planner. I seek guidance on how to get started, including setting up the software, configuring flight controllers, and understanding key features like mission planning, telemetry, and real-time monitoring.
I also completed two flights, but during this flight, unexpected yaw, pitch, and roll motions occurred. Please tell me briefly how to fix this. Also, if you have any parameter guide other than ArduPilot, please share that with me."
Let me know if you’d like help diagnosing the flight behavior more specifically — for example, whether you’re using a custom frame or have modified PID parameters.
This is the Second Flight Params flight with logs: -
