Sorry but I misunderstood your first post. I thought you plugged them in to charge and left them. If I have freshly charged batteries and I have to leave right away, I place them in the oven temporarily while I'm away. I live alone so no chance someone will crank the oven on with the batteries inside. The warning on the packages I've read mentions to keep a close eye on freshly charged batteries 15 to 30 minutes after being charged. I saw a YouTube vid of a guy who lost an entire garage full of planes and a Mercedes Roadster because of a lipo battery fire.
Guys at my LHS claim LiFe batteries are more safe compared to these lipos.
