Just a thought Screwball …… I would be wary of selling these to ‘just anyone’ around your campfire without additional info. Its possible they wont know much about Li-ion safety or what ‘could happen’ if they dont use common sense and are aware of the consequences of not following a few guidelines. I would point them to this(and the other Z1) thread and maybe prompt them to read Lithium-ion battery safety 101 Lithium-ion battery safety 101. They should understand that some have reported problems and be aware of that so they can monitor their lantern(in case it is a ‘dud’) …… it would be a tragedy if there was a problem and it caused a tent fire in the middle of the night simply because they lacked the info.
