Stupid question.. But based on all the posts here one would think this is the place to get the information.. These batteries that are highly dangerous, are they different to the batteries in say the istick 50w or the mvp 3, or is it just that the istick and mvp3 have safety features in place that should prevent this? Is the iStick and mvp3 safe to carry in your pocket with say your car keys? Cheers guys.
