So mods that take external batteries seem to have vent holes of one kind or other. But my Innokin MVP 3 Pro (which has an integrated battery) has no vent holes on its outer shell. I'm wondering if this is a safety issue. What would happen in the event that its integrated battery somehow failed?
I'm guessing there's a logical reason for this, so apologies in advance if dumb question!
