In today’s fast-moving industries, equipment manufacturers increasingly require power solutions that deliver higher capacity, greater reliability, and longer service life. As a result, many brands turn to advanced power technologies—especially Custom 6000mAh Li-ion Cell solutions—because they provide unmatched performance and flexibility. Since 2008, Keeppower has focused on delivering high-quality, custom-engineered lithium power systems, and our newest Protected Type-C 21700 Custom 6000mAh Li-ion Cell reflects our deep commitment to innovation, safety, and consistency.
To help customers stay ahead in competitive markets, we offer a full range of customization options. Moreover, we integrate cutting-edge materials and safety systems that make our power solutions stand out globally.
Why the Custom 6000mAh Li-ion Cell Stands Out
The demand for high-capacity lithium-ion batteries continues to rise across industrial, medical, security, and consumer electronics markets. Therefore, we engineered our Custom 6000mAh Li-ion Cell to deliver exceptional energy density and uncompromised safety. With a typical capacity of 6000mAh (minimum 5800mAh) and a nominal voltage of 3.6V/3.7V, this powerful cell provides strong and stable output for devices requiring long runtimes.
To further improve performance, we utilize an advanced 21700 cell structure, which offers improved thermal stability and higher discharge capability compared to traditional 18650 batteries. As a result, brands can integrate more capacity in the same device footprint while also enhancing system reliability.
Additionally, the cell supports Type-C input charging with a standard charging current of 1.5A, ensuring faster and more convenient recharging. This makes it ideal for next-generation devices that prioritize user convenience and efficient power management.
Advanced Safety and Material Advantages
Because safety is non-negotiable for industrial applications, our Custom 6000mAh Li-ion Cell is built with a Japan-made protection IC, an essential component that ensures the battery remains safe under all operating conditions. The integrated circuit protects against overcharge, over-discharge, short circuits, and overcurrent, reducing the risk of damage and improving long-term reliability.
Furthermore, the Type-C structure includes a high-precision power path, which enhances charging stability and reduces heat generation. Combined with premium lithium-ion chemistry and high-purity raw materials, these features contribute to over 500 charge–discharge cycles with minimal capacity loss.
To support global compliance requirements, the cell meets major certification standards including UN38.3, CE, ROHS, MSDS, and Regulation (EU) 2023/1542. This international certification framework ensures that our customers can smoothly deploy and ship their products worldwide.
Flexible Customization for Industry-Specific Needs
Because every application is unique, Keeppower provides extensive customization options for the Custom 6000mAh Li-ion Cell. You may choose button-top or flat-top designs, define a maximum discharge current up to 10A continuous, request private labeling, and customize packaging and assembly.
Where the Custom 6000mAh Li-ion Cell Excels
Because the Custom 6000mAh Li-ion Cell supports high discharge currents and long runtimes, it is widely used in:
Professional flashlights and tactical lights
(requires strong output and safety protection)
Portable medical devices
(where stable voltage and reliability are essential)
Smart tools and IoT systems
(demand continuous, high-efficiency power)
Communication equipment and backup systems
(benefits from long-life energy storage)
Outdoor gear and emergency kits
(requires durable and dependable battery solutions)
By combining long cycle life, stable performance, and advanced safety systems, Keeppower ensures that the cell remains dependable even in harsh operating environments.
