    I tried to find this information in the manual and couldn't find an answer. I had the drone outside sitting for a few hours tonight and its only about 10c outside. Before I put it away I thought I'd take it up for a quick spin around the yard. As soon as I started the engines it cut out giving me the alarm that the battery was below 15c and I had to heat it up. I was just wondering this is fine because I was on the ground but what would happen if I were in the air? Would it alarm only or cut the engines off as well? I hope its not the latter because I'd rather risk damaging a battery then lose the drone.

    Interesting... The specs on DJI's website says the P4 operating temp is 0c. So the battery has a different range? Also, DJI shows a video of a sled dog guy using it in winter. Didn't look like it was above 0c but I guess that's marketing!

    There is a risk with the older generation birds that the battery could shut down due to a combination of voltage lag and cold temps. The newer crafts won't let you launch, or will force a landing if you're nearing that situation. Rule of thumb is you want at least 20 C battery temp. You'll get warnings 15-20C. 15 C is auto land. The running of the battery will generally keep it warm allowing you to fly in air temps well below 20C.

    The software temp limit is a feature to prevent battery failure in flight. LiPO performance decreases with lowering temperature (increased internal resistance, reduced deliverable current and available capacity). No issues flying in lower temps, you just need to pre warm the packs. Leave them on the seat of your car while traveling, carry close to your body etc. if you left the AC powered the battery would have reached the required temp while powering the electronics at idle.

    You won't be able to get your Phantom into the air before the battery has been warmed up. So, this would never occur mid-flight.

    Ok msinger if the battery was warm enough to take off will it generate enough heat to keep it warm even in frigid temps? I am wondering with the drone just hovering in the cold if it will produce enough heat to maintain the temperature. I was wanting to use the drone to film some of our jeep snow runs this winter/spring. I would hope that the app/drone is smart enough to know its in mid air and not cut the engines off because the batteries are too cold.

    As long as you are in the air, the battery is going to keep itself warm enough and will not shut off. If the drone detects that something is going wrong with the battery, it will flash some warnings and make sure you know something is wrong or land itself. The drone will never just shut itself off in the air.
    I have flown well below 0 Celsius in the winter. The flight time is a bit shorter but no issues with anything else.

    If you observe what your typical battery temp increase is, even during a gentle flight, you will find it is always 20+ deg C. Even at -5 you won't go below the magic 15 number. What you may see is the occasional propulsion limited output error as current delivery is reduced at lower temps.

    FWIW, on Page 26 of the manual it states:

    "In cold environments, insert the battery into the battery compartment and allow the aircraft for
    approximately 1-2 minutes to warm up before taking off".

    I plan to fly in temps down to -10C (14F). I'll be taking the drone out of a warm house or car and flying right away. The craft and battery will be at room temperature at take-off.

    Last spring there was some post about cold temp flights. Airontario was taking his p3 out at minus 20c with succes
