When I returned from the field one day I decided to leave all my gear in the back of my pickup under the canopy because I was going to go flying the next morning.  I parked the pickup in the garage.
The next morning I went out and found that my lipo battery had ignited and burned and even burned the tool case that it was sitting on.  If it hadn’t been for LipoSack I probably would have lost my pickup as well as my garage.
