By request from a different forum, I did this little experiment.
I don't know exactly what it proves, except for that the switch is not airtight and allows venting. I strongly believe this does not prove the iHybrid (or any other PV with some little vent hole/space/switch) is "safe" to use with unsafe chem batteries. Moreover, using a Genisis style atomizer with a Lithium Cobalt battery is not a good idea because these batteries may not tolerate well the momentary current draw of a partial short which is so common with our coils at least in the beginning.
ONLY USE IMR batteries with the iHybrid or any other Genisis style.
