Hello All, I have a question on battery storage in a car on a hot day... We are going away this weekend and I plan on taking my H I plan on charging and topping off my four batteries and the ST16 and putting them in my backpack I will leave in the hotel room Thursday night but Friday morning I'll put everything in the back of my car in case I find something interesting to fly around. Everything will be in the back seat and probably be left there most of the day closed up with the temperatures expected to be in the 90's. Same thing for Saturday... Is this safe for the batteries with the high temperatures, or should I just leave everything at home? Any suggestions? Thanks !
