Efest 18650 Batteries & Chargers

Efest is the premiere manufacturer of Li-On batteries, based in Shenzen, China. They were the first company to introduce high-drain IMR batteries, specifically catering to the vaping industry. IMR batteries do not have a built-in PCB, but have a much safer chemistry composition than ICR batteries. They are able to handle much higher loads and are essential for safe sub-ohm vaping. Because of the popularity of Efest batteries, other Chinese companies starting making fake products with using the Efest brand, spurring the company to include an Anti-Fake label on all of their products. You can verify the authenticity of your product by clicking here.
