Hate to say it, but the fire safe's don't work. A little 800mah lipo pack destroyed a fire safe and almost burned my house down. The pack puffed, I put it in the fire safe, closed it, put it on the back porch of my garage… came down at 1am to the smell of smoke, whole side of house was charred. fire safe was almost gone. Everyone talks about a fire safe, thinking it will work…I unfortunately tested it.
