The term 26650 defines a standardized cylindrical lithium battery size: 26 = 26 mm diameter, 65 = 65 mm height, 0 = cylindrical form.
With a significantly larger diameter than 18650 and 21700 cells, the 26650 format provides greater internal volume, enabling higher capacity, higher discharge capability, and enhanced mechanical robustness.
26650 batteries are known for their durability and power capability, especially in demanding environments. They have superior energy capacity(5,000mAh to 6,000mAh), robust power delivery (high discharge exceeding 40A), excellent thermal stability, and simplified battery pack Construction.
26650 batteries are commonly used in industrial and high-power battery packs for power tools, backup power units, emergency lighting, portable energy storage, heavy-duty flashlights, and specialized industrial equipment.
Our customized 26650 battery pack solutions are engineered through an application-driven design process that combines carefully selected cells with optimized series-parallel configurations, integrated battery management systems for protection, balancing, and monitoring, and mechanical structures tailored for heat dissipation, vibration resistance, and installation constraints, enabling OEM and industrial customers to achieve reliable long-term performance, simplified system integration, and enhanced safety across diverse operating environments.
