Yes. Having these current temperatures (over 30
degrees Celsius), is rare in here and manifests no problem. When temperature drops near freezing, then problems start. We have short summer and most of us want to continue flying even winter.
People living in warmer climate have no problem with LiFe.
When we were flying icu ducted fan planes we sometimes had to warm up them using gas turbine engine exhaust, just to be able to start them
We even have a propane burner inside kinda tent contraption, keeping pilot warm while flying
I understand this seem alien for most of my fellow hobbyist.
