RE: Welcome to the FMA Direct - Kokam LiPo Support Forum
Hi Larry,
Yes, you can get them wet without issue. I have never submerged them so I'm not sure what happens.
It is actually better to store Lithium cells at freezing temperatures when not in use. Doing so, keeps their capacity healthy. I keep mine in an unheated garage during the winter months and warm them up for a day if I decide to use them.
Since the Lithium packs are only volatile during charge, you can keep them in a cardboard box for storage.
