NOTE: The mechanical mods and repairable atomizers are exclusively for experienced users with knowledge of Ohm's Law. The use of high performance / amperage IMR batteries and in perfect condition is recommended. Do not use batteries that have suffered falls, that have deformations in the structure, damage to the outer sheath or sparks at the poles. From Sapporet we recommend the Sony VTC5A battery with less than 200 charge cycles for safety. We are not responsible for the misuse that the user may make and for the possible damages caused.
