with all this talk of batteries blowing up, I've gotten a tiny bit nervous. I'm thinking about buying these: http://www.ebay.com/itm/190896886816?_t ... 6ga4m%3DT3 and wanted to know when I should use them? While charging? flap closed? just to store my batteries? in the phantom case, it looks like there are 6 slots for batteries but they won't fit the bags too. is it safe to store them in the case? if so, lid open? I don't want to die. not concerned about the house, its insured.
