Cylindrical NCM Cells

18650 and 21700 lithium-ion cells in high-rate and high-energy versions for cordless tools, garden tools, vacuum cleaners, e-bikes and portable storage.

EVE's cylindrical NCM range splits into two families. The P-series (20P, 25P, 40P, 50PL) is built for high continuous discharge current, the profile cordless drills, saws and mowers need. The V- and E-series (26V, 29V, 33V, 35V, 50E) trade some current for more capacity and longer cycle life, which suits e-bikes, scooters and portable power packs.

According to EVE, the company has supplied more than 2.2 billion cylindrical cells and serves leading power-tool, garden-tool, e-two-wheeler, vacuum-cleaner and portable-storage brands. Its cylindrical cells carry CQC, UL, UN38.3, IEC, BIS and PSE certifications.
