You should also consider removing the ground wire connected to the UBEC as this completes a ground loop path created in conjunction with the ground wire in the Throttle Out - ESC path.
Yes, your Camera and Mic are getting power from your second battery through the OSD Pro. This is called 'Pass-Through'.
You can remove the second battery and power all from your main pack but be sure to make the changes above to remove the ground loop.
If I'm using the CC bec 10A do I still remove the ground wire on the ubec?
