While PCBs are needed in some batteries and uses, the more advanced Li-ion chemistries (IMR and INR Lithium-ion) are considered to be safer and do not require protection circuitry.
Protected cells are great for high performance devices and electronics, and are commonly recommended or designed for specific compatible models to get the most consistent efficiency while keeping your device and battery safe with the on-board protection.
High capacity lithium batteries usually require a PCB (Protection Circuit Board) or other kinds of protection (like a PTC aka Resettable Fuse, and a CID Pressure Valve) to limit over charging, discharging, high temperatures and internal pressure.

It’s hard to say exactly how long it takes before vaping-related pulmonary diseases occur in people, or what their health outcomes are in the long-term, because the trend is so new, says Michael J.

Formaldehyde is another (a known human carcinogen) and benzene (found in car exhaust). So what ingredients can you find in your electronic cigarette? Let’s start with propylene glycol (also known as antifreeze), and acrolein, frequently used as a weed killer.
