I am a newbie - I have had my P3 for about a week. After I fly for a while and use up 50ish% of my battery I often find that it will not charge right away due to it being too hot. Is this normal? I live in Toronto so ambient temperature outside is about 25C and about the same inside the house. What's the best way to cool it down? Can I put it on a heating/cooling vent in my house with the AC running? Or is it a bad idea to cool them down too quickly?
