Samsung

High-drain lithium-ion cells-like the 25R (2500 mAh), 30Q (3000 mAh), and 30T (3000 mAh) series-are developed by Samsung SDI, the battery branch of Samsung Group. These cells are favored in vaping devices for their dependable performance, extended life cycle, and continuous discharge rates up to 30 A. Even though contemporary packaging often warns Not for Vape, vapers continue choosing Samsung cells for aftermarket modifications due to their consistent chemistry and built-in safety features (PTC, CID protection) preventing overcurrent and overheating. Samsung SDI operates large ISO-certified facilities in Korea and China to supply global demand for consumer electronics, EV batteries, and high-performance 18650/21700 cells.
