从China供应商批发进口18650 Li -Ion Battery — FOB条款

This 18650 lithium-ion cell from Dongguan Sunly Battery Technology delivers 2500mAh capacity at a nominal 3.7V, with a listed current rating of 2A. The cell uses a lithium metal oxide cathode paired with a graphite anode and a LiPF6-based electrolyte, which is the standard chemistry configuration for commercial 18650 cells used across consumer electronics and portable power applications. The cylindrical format measures approximately 18mm by 65mm, fitting standard 18650 battery sleds, holders, and device compartments.

The 2500mAh capacity positions this cell in the mid-range of 18650 offerings, suitable for applications where moderate capacity and reliable cycling matter more than extreme discharge rates. Typical uses include LED flashlights, portable power banks, cordless tool battery packs, and e-bike assemblies where multiple cells are connected in series and parallel configurations. The lithium metal oxide cathode chemistry provides a good balance between energy density and thermal stability, though end-product designs should always incorporate a battery management system to monitor cell voltages and temperatures.

Dongguan Sunly Battery Technology supplies this cell from Dongguan, Guangdong, one of China's primary manufacturing hubs for battery components. Buyers importing for assembly into multi-cell packs should confirm the supplier's capacity matching process, as cells within a pack must have closely matched internal resistance and capacity to avoid imbalance. Request datasheets, UN 38.3 test certificates, and sample cells for independent testing before committing to a production order.

Dongguan Sunly Battery Technology Co., Ltd. is located in Tangxia Town, Dongguan City, Guangdong Province, China. Dongguan is a major production base for lithium-ion cells and battery pack assembly in southern China, with a dense supply chain of cell manufacturers, BMS suppliers, and pack assemblers operating in the region. The company's address places it within this established battery manufacturing cluster.

The supplier's platform profile shows a harbour trust tier with a 0.00% response rate, meaning no tracked buyer enquiries have been answered within the platform's monitoring window. This does not necessarily indicate inactivity, as some suppliers operate primarily through direct channels rather than platform messaging, but it does mean buyers should use alternative contact methods and expect variable response times. Confirm the company's production capabilities, minimum order quantities, and export licensing before placing orders.
