November of 2015, some places are snowing already, some places are just getting cold, but it doesn’t stop us from flying…However we have to be careful flying in this weather conditions…

All we know that batteries used in DJIaircraft are Li-Po batteries. Li-Po stands for Lithium-Polymer, which means it allows us to withdraw a lot of power out of small battery pack.
Basic knowledge:
1.      Full charge your battery before each flight.
2.      Never overdischarge your battery
3.      Cycle the battery by discharging to 8% and full charging again every 20 flights
4.      Intelligent flight batteries can automatically discharge themselves to enter storage mode
5.      Discharge time depends on users settings and takes from 1 to 10 days
Alright, let’s get back to our topic. Since Li-Po batteries are not made to fly below 0 degree C battery performance can be not as good as in a normal temperature 5C to 30C
Low temperature flight negative consequences:
1.      Shorten flight time
2.      Fast voltage drop
Ways to prevent the issues described up there:
1.      Never store packs in cold
2.      Start the motors but don’t fly up, let your bird to warm up for a minute.
3.      Please keep
the aircraft
hovering  for 30 to 60 seconds before taking further action.
4.      Do not keep the aircraft fully accelerated for long time.
5.      Be gentle on a RC sticks
6.      Outdoors keep your batteries in thermal insulation box with bag of hot rice  
(Uncooked rice warmed up in a microwave keeps  temperature very good)
7.      Inspire owners can use the battery insulation stickers

8.      Inspire owners also can use a battery heater to pre-heat their batteries before the flight.

Here is the video I really like, at 1:20 on a timeline professional pilots from DJI Studio talking about batteries usage in extreme cold conditions
Fly safe and have a great winter!

I am trying to order Insulation stickers for 2 months without success now. Ok I am not willing to pay 20,- postage for a letter and I dont pay 5,- for a 2,- product like many dealers try to sell it up to 5x retail price.

So I could find not ONE dealer in my area where a) I could pick it up - NO ONE HAS THEM b) I could order at normal price - incl. amazon and ebay of course where you also cannot buy it.

The video is very interesting - but would be fine to know how they fly. Is it Atti or autonomous? I see they fly below 2m following the vehicles - is this really safe no to crash it into the road? Also do they have sensors switched on or off? If on why is the snow not a problem like the manual says?

Great reminders Tim.

We Canadians have to keep that in mind at all times.

I did some flying around last weekend around +5C and already felt that the batteries discharged a bit faster.

None of the less, still I had the usual blast.

Could be a good thing to have a spare battery in a pocket ner your body, when it's cold outside.

Great stuff Tim. Also a reminder to let the camera adjust to the ambient temperature outside prior to installing the battery. In doing that the camera lens will not fog up.

One piece of gear that I find "handy" are Millar Mitts and after each flight I pull the battery and use it to warm my hands.

Thank you for posting. But, why does the manual that came with the battery say it can be used between -10C to +40C?

Hi RozBujnik,

Yes you can use the battery at -10C but don't expect it to discharge the same rate as at +25oC.

That is not DJI that is the nature of the LiPo technology.

Cheers.

How risky is it to fly a Phantom 2 during a snowfall? I've gotten great usage out of it already and I'm willing to get another money shot at my drone's expense. Is there any way to protect and wrap the copper coils?

Good write up, but call me superstitious if you must, I take exception to #3)  hover 30-60 sec before further action....

My take on reading about real flyaways is the majority of real flyaways happen during no stick input hovering....  I NEVER hover for 30-60 sec:  I use that time slowly moving the sticks to keep action happening and not let the little guy get bored and decide to head for the west coast of Africa....  why take chances?  just jiggle the sticks a little during this warm up period, still gets the job done....

yes, it totally works, being soft and gentle on a sticks is pretty much the same as hovering. Main point of it is not to make any movements that will increase battery current amperage

This picture explains everything, but the only thing i don't understand is a green line. seems like once you turn it on, battery voltage drops down to 3.0v (which almost brakes the battery) and it grows back to 3.3v ?

Yes! That is the case in the extreme -40degC and the reason for the follow up Vol increase is the battery temp rise once you have current drain. That is why one should never use cold battery in the extreme low temp environment and the Battery Heater is an option “worth a gold”

Does this apply to let's say 50-60deg weather too? Or just super cold weather that is below 40 etc.?

I use those pocket heather inside a small isolated lunch pack with my batteries inside to keep them warm and ready.

I plan to do aerial footage in mountain areas near Gatlinburg, TN, in late January or early February. I already ordered a battery heater and have some stickers. Is it fair to say that both can work in conjunction? Once I put the stickers on, should I ever remove them? Are they to only be used during the colder weather? Also, does anybody know about how long the battery will drain when using the battery heater?
