The batteries used in vaping devices can be very dangerous if used improperly. It comes down to how the user chooses to use, store and maintain them. Almost any battery in the world used improperly does pose a fire risk. Lithium-Ion (LION) batteries do store massive amounts of energy and if they are used improperly they can do something called “venting” or as other people like to say “they blow up”. Reported cases of battery venting are when users use an unregulated device with an incorrect custom built coil.
