Are you looking for fire rated bags or telling us you found some?
There are many listed on eBay. If you haven't already, watch some of the test videos on YouTube. Very scary!!
I think im going to build a cement block type charging station in my basement. store my battery's in a metal tool box lined with drywall (youtube method). When I wanna fly Ill take a chance and load the battery's into either my backpack or pelican case along with the Bird.
6 total Batteries. However I'm afraid one is damaged as it does not seem to correctly hold a charge. So I'm currently not that battery at all till I figure out for sure if it's junk.
