Temperatures right now are relatively warm for me, around 0ºC or so. I do fly in freezing temperatures, down to -15ºC and have not experienced any real negative impacts on battery life. I always keep my batteries warm inside my coat and get up in the air as soon as possible. I had the
I2 out on a filming job where temperatures were around -5ºC or so, 13 knot wind gusts and the
I2 sat out on the snow exposed without batteries installed for nearly an hour. Took the batteries out of my coat and was up in the air flying fine.
