Thanks guy's for the input, I run polyquest packs and I would hate to lose one. But I feel a little safer now. I have another concern about lipo's (something I heard) if you get them wet they are f....d, so I dip the ends of my packs in plastidip you know that rubber tool handle dip to seal and water proof them. It's realy not that messy and it looks kinda cool when I'm done. I dont know why water kills the cells either.
