Ditto on what others have said.....Thousands of lipos sit on store shelves and racks all the time, and I've never heard of one catching fire or exloding in the store. If this was a problem, I'll bet the store's insurance companywould mandate some type of special storage.....I do keep a close eye on them while charging and ones that are damaged, are, discarded, if they exibit any weird tendencies....Pat
