Test with a fully charged battery. The fully charged battery will be at a higher voltage resulting in more amps.The battery was about 80% charged.
The 710W on the spec sheet are the maximum amps for the motor assuming maximum airflow for cooling. Running a 710W motor at 820W and it will burn out very quickly. My guess would be it would last about one min at 820W before burning out. Depends on how optimistic the rating is. You should limit your maximum throttle or use a smaller in diameter and/or pitch prop.At 70% throttle, the current was around 27A, and at 99% it was around 58A. The power on the meter was reading about 820W at 100%.
The spec sheet for the motor shows Power 710W. What is this for?
This is incorrect. The spec sheet shows a recommended range of props to give you some idea what props size you could use. You can put any prop you want on it as long as you stay under 710W. Putting a smaller prop on it will not damage the motor.The spec sheet also shows the minimum prop should be 11x8.
