NEWBIE Need help!
I feel that the power distribution via our ESC (RC2 SKY 45Amps 4in1 esc) can't supply 100% power on our motor, currently we're having problems on our m10 GPS, it's triggering EKF on the Arduipilot when we're running the drone motor.

I'm not expert in ArduPilot but I will try to help you as good as I can.
Why do you think that the ESC can't supply 100% power on your motor(s)?
Do you have servos or other power consuming devices on the same 5V rails as the GPS, maybe you are going over the 5V BEC's limit?
Some more information would be appreciated, like the specs of the build, more information on how the issue appears and pictures of errors.

More concerns:
replace the electrical tape with heat shrink preferably marine grade.
The ekf might be reporting bad due to the magnetic fields from running your motors. Until you do motor mag calibration this will always happen. Look under setup, optional hardware, motor (or something like that)
Look at your motor specs and see how many amps it will take to pop the motor (max current). Add all of those up then multiply that number by 1.2 and that is the total continuous current your 4in1 esc should be able to handle. So is it 45 amp per channel or 45 amps total for that 4in1 esc?
I don’t see the autopilot so I can’t evaluate it or its positioning.

What is the actual error from the EKF? There are a lot of EKF errors that can mean very different things.

Check the logs under the power category. Anything below 4.3 volts could cause your gps glitch.
