All, We are currently working on a new handheld product that will be tested for IP67 Water Ingress (1 meter submersion for 30 minutes) and we are trying to determine the safety impact of not including the lithium ion battery pack as part of this rating. This product will be UL60950 Listed. One question that has also been asked of me is whether this battery pack needs to be vented. A few lithium ion cell manufactures whom I have researched on this say that the pack should definitely be vented. If vented then the IP67 rating on the battery pack is definitely out of the question without designing some costly pressure release mechanism.
I guess my ultimate question is, how safe is a lithium ion battery pack if water is introduced in to the circuit? Any help is greatly appreciated. Regards, Alex McKinney Safety Engineer LXE, Inc.
