I hope, that our smart Anafi battery NEVER will come to the opinion "battery temperature too low" while in mid-flight (and cut off power).I flew at similar temperatures, and it happened to me that the phone gave me the message "temperature too low to charge the battery", but this was a telephone warning. clearly taking off and landing on the hand. No problem with the drone. One day I left the battery on the drone and I had the message "battery temperature too low". In that case I had to put a hotter (which I had in the jacket) otherwise it did not even start the engines. Apart from keeping the batteries warm, and then unloading them a little, winter flights can be done.
