Sparky, having watched in horror at some of those ebike battery fires on video and imaginging that were my battery on fire, I kind of believe maybe a 1/4 inch steel, welded, enclosure might be the trick. Of course, the pressure from each group of cells going off will severely test whatever hinges are on the steel box.Is there anything that can safely contain a lithium battery fire? To even suggest such a bag is needed does not speak well of Magicycle batteries.
maybe if they used better batteries they would not need the bag??
