We were out on a job yesterday with the Inspire ProX5, where the temperature was about 5 dgerees C. We flew well with five batteries, with no problem, as we kept the batts in the car. However, on the sixth battery I couldn't start the Inspire. I got a warning saying something about the battery is below 15 degrees! The battery had in fact been sat outside on the floor for about 15 minutes, but even so, it would not have dropped significantly from the 5 degrees air temperature. Besides, would this really have prevented the aircraft from starting? When we got back home I left the battery on the table for two hours and then found that ithe Inspiure started with no problem at all.

Is this normal behaviour for the Inspire batteries?

Yes, it is. They're very sensitive for low temp (firmware inflicted). Invest in electric blanket and warm'em before leaving home.

Like Dobmatt mentioned, these batteries are extremely sensitive to the cold and there can be some major consequences in flight should the battery not be allowed to warm up. DJI does sell battery warmers for this reason, and other customers have used other methods to get them warmed up for safe use.

I was flying one day last winter and landed to change battery. Switched battery then a curious onlooker engaged me in conversation for only 2 or 3 minutes. When I tried to take off, got cold battery indicator. Changed it to another that had remained in the case and all was fine. As others have mentioned, these puppies are very sensitive to the cold. Starting out. Of course, after flying a minute or so, they get quite warm, even in the cold. But they need to start off warm.

Ah, OK. Thanks for the feedback guys, appreciated. We haven't done much cold weather flying, so I guess it's a learning curve. I've just ordered a thermal box and some gel hand warmers. I will look at a more permanent way of keeping all the batteries nice and warm in future. Cheers.

I've had the same warning, popped the battery in my pocket for less than five minutes and Presto, working again. In cold weather, I keep half dozen batteries down the front of me keks, an old boy scout trick (be prepared).

So when some gal comes up to you they can say " Are those batteries in your pocket....  or are you just Happy to see me !  ( q -rimshot in the backround )

***By the way are from the States originally ?  I thought you were from Jersey ?  Just to be fair, I live in the USA -East Lansing, Michigan to be more precise .

Donnie,  I'm not sure why it says Jersey but I actually live in Guernsey, born and bread.
