Multi-battery / How to operate multi-battery flights

You can fly a multi-battery mission with Pix4Dcapture. Pix4Dcapture for iOS and Pix4Dcapture for Android provide different workflows to perform a multi-battery mission.

If you cannot safely capture your project area with a single drone battery:

Android (Available only for Grid missions)

  • Tap ABORT. Your drone will start to loiter, and Pix4Dcapture will create a new flight plan that covers the remainder of your project area.



  • Tap GO HOME. Your drone will return to land at its home point.

After you have changed your drone's battery:

  • Tap START. Your drone will start capturing the remainder of your project area. Note that your drone will start capturing photos at the beginning of the flight line that it was flying in the previous mission when you tapped Abort.



iOS (Available for Grid, Double Grid, and Polygon missions)

  • Tap PAUSE. Your drone will start to loiter.



  • Tap GO HOME. Your drone will return to land at its home point.

After you have changed your drone's battery:

  • Tap RESUME. Your drone will start capturing the remainder of your project area. Note that your drone will continue capturing photos just after the location of the latest picture acquired before you tapped Pause.

    Hi Gaël,

    I flew the same double-grid mission in Fast mode, per your suggestion. The first part of the mission was pretty successful with only a few anomalies e.g. few dropped pictures and sometimes pretty uneven spacing between shots. The drone then continued for the second grid of the mission and as you can see below it stopped taking pictures after the second path in the grid althought the drone kept flying for another 2 or 3 paths before I got the first low-battery warning. See screenshot below. Can you explain the anomalies and also why the drone stopped taking pictures but continued flying? I can send you the complete quality report if needed. Thanks!

    Hi Gael,
    I made another attempt flying the same mission and noticed the following issues:
    1. This time the mission was successful until I reached a low battery notice at 25% . I hit the PAUSE button and the drone loitered. So far so good right, however, the drone/app did not respond to the “Go Home” command. The drone started to land at the point of loiter and I had to take manual control to take it back to the home point. Then I changed the battery but was not able to RESUME the mission. The app seems to be “frozen” and although I replaced the battery, the app kept telling me the battery level was insufficient to resume the mission. The app didn’t respond to anything so I had to kill it.
    2. I then restarted a single grid mission in an attempt to capture the remaining portion of the double grid. In the midst of the mission, the camera stopped taking pictures although the drone continued its flight pattern. This is a problem I reported before but have not heard back from you on!

    I’m diligently following your instructions and recommendations but continue running into issues that prevent me completing my project using your app. Please advise!

    Hi Hendrik,

    Sorry for the delay in my answer.
    From all your reports, it seems that the multi-battery missions using an iOS device and flying a double grid are quite unstable. It has been reported to the developer's team.

    In a general way, each time an unexpected behavior occurs, we recommend interrupting the mission and restarting it from scratch. To do so, close and force quit the app, disconnect the cable from the mobile device, turn off the remote controller and the drone. Then switch on the drone and the controller, reconnect the USB cable and open Pix4Dcapture.
    Are you able to reproduce the behavior you are describing in Fast mode?

    In the meantime, even if it maybe not the most efficient workflow for you, I would advise:
    - Keep using the Fast mode.
    - Avoiding running multi-battery missions with double grid missions.
    - Trying if possible the Android version of Pix4Dcapture.

    When planning a mission which will require multiple batteries, does the take-off location always need to remain the same?  I have a mission planned where I may want to change my take-off location when changing batteries.  It's a long corridor that may have sections obscured and will require changing locations.  Is this possible?

    Hi Andrew,

    In order to guide you the best way, can you tell me if you are using the iOS or Android version of Pix4Dcaputure?
    Also, what is your configuration? (drone, camera, mobile device)

    Hello Gael,

    I am using iOS (iPad) and my drone is the DJI Phantom 4 Pro.  The camera is the stock one that comes with the drone.
