How to Hot-Swap Batteries on the M300 and M350

For large missions requiring multiple batteries.


  1. Ensure the M300 or M350 propellers have stopped after landing.
  2. Have a set of batteries ready and bring them to the drone.
  3. Unlock the batteries on the back of the M300 or M350 while holding 1 (one) of the original batteries in place.
  4. While securing one battery, remove the other.
  5. Insert a new battery into the vacant slot. 
  6. Lock the batteries in place to ensure the new battery is fully inserted in the battery slot. 
  7. Unlock and repeat steps 3-6 for the other original battery. 
  8. Takeoff! 
No need to re-do your figure 8s if you didn't power cycle the unit. Just fly back to the last point collected in your mission and resume.

If your return to flight is delayed by more than 3-4 minutes, it is probably better to end the collection and start a new data collection.
