n233w,

I agree that storing the lipo packs off the house or garage is the good idea. But during summer months in Southern states, the outside temperature could can reach from 90 to 100, which may not be good to lipo packs.

Saylors,

Yes, the storage bags are just an extra piece of mind. Personally, I would store them in these bags, and then in file cabinet, or ammo boxes.
