I've been in the hobby long enough to know two people who did lose their garages or part of their homes...I think dantley had a similar problem as well? I always make sure the proper number of cells is showing on the charger, and NEVER leave the batteries. I have a smoke detector sitting above them and fire extinguisher right next to it. My error was using a cheap ass off brand pack that were probably QC'd by a ten year old while he was watching cartoons. I still use lipos for my jets, but I have them taped together and easy to remove out of the plane to charge. Newer projects are A123.
