Considering all the major battery manufacturers are on the record stating that their batteries are not designed for use in e-cigarettes, any incident involving battery safety has the potential for shutting down any business that sold the battery to the individual. There may not be monetary damages involved, but if enough sources are shut down that provide batteries for our mods, where will you be when you can't get good batteries any longer?
Vape shops are highly complicit, in that they provide these products and do not tell the customer anything regarding safety and safe use/storage. And considering they also sell batteries with grossly exaggerated ratings, they're just as clueless as those who buy them.
