18650 batteries are widely used in power tools, energy storage systems, electric mobility, and industrial electronics requiring stable, high-capacity rechargeable power.
⋙
The term 18650 refers to a standardized cylindrical lithium battery size: 18 = 18 mm diameter, 65 = 65 mm height, 0 = cylindrical cell. This standardized format allows 18650 batteries to be easily integrated into battery packs, modules, and custom power systems across multiple industries.
18650 batteries are valued for their balanced performance and system flexibility, including: high energy density, stable voltage output under continuous discharge, good thermal behavior, exceptional cost-effectiveness, long cycle life, incredible design flexibility, and mature global supply chain and proven reliability.
18650 batteries are commonly used in battery packs rather than as single cells, powering applications such as power tools, portable energy storage, e-bikes, medical equipment, robotics, backup power systems, and industrial electronics.
Their standardized size allows engineers to configure series and parallel arrangements to achieve required voltage, capacity, and discharge performance within compact designs.
We provide customized 18650 battery solutions tailored to real-world applications, including but not limited to: custom voltage and capacity configurations, cell selection based on energy, power, or lifespan requirements, integrated BMS for protection, balancing, and monitoring, mechanical design optimized for space, vibration, and heat dissipation. We support for OEM, ODM, and project-specific requirements.
