Abstract: Aspects of the current subject matter relate to methods and system for protecting a battery cell and/or a /pack of multiple battery cells serving as a power source of a vaporizer device from developing a short-circuit in a vaporizer device. In one aspect, a vaporizer device is provided. The vaporizer device may include a power source including a battery and a power source lead extending outward from a distal end of the battery. The vaporizer device may further include a printed circuit board (PCB) electrically coupled to the power source via the power source lead extending outward from the battery. The vaporizer device may further include an insulator at least partially surrounding the power source lead. The insulator may be mechanically coupled to at least one of the power source and the PCB.
