DaVinci IQ 18650 Battery
Sneaky Pete Says:
Take your IQ even further by adding an extra battery. The IQ produces huge vapor clouds with ease in a portable and pocketable size, and you can infinitely increase your session potential by popping in a new battery when you run out of juice. These 18650 batteries are the exact same ones that are used in your IQ, so you can rest assured that they are safe to use in your vaporizer.
