6.4V 6400mAh 26650 Battery Pack FAQs
Can I customize this battery pack (e.g., 1S2P, 1S4P, BMS, connectors)?
Of course. In order to match your product design, we allow OEM/ODM customization for different configurations, wire length, connections, labels, and housing materials.
Why choose LiFePO4 (LFP) over other lithium chemistries?
LiFePO4 offers a superior safety profile, longer cycle life, and more stable thermal performance than other lithium chemistries (like NMC or LCO). It’s especially well-suited for applications in demanding environments thanks to its excellent resistance to overheating, overcharging, and deep discharges.
What are the benefits of using a 26650 cell compared to 18650?
26650 cells provide higher capacity and better thermal performance while maintaining a compact cylindrical format. This allows the battery pack to deliver longer runtime in a relatively small footprint—perfect for space-limited enclosures like security camera housings.
Do you provide testing and certification services?
CM Batteries can help with certifications like UN38.3, IEC62133, and others. Testing reports and MSDS are also accessible.
Can the battery be integrated into solar-powered systems?
Yes. This battery pack supports solar recharging systems, and we can help design a full solution including charge controllers and mounting kits suited for outdoor, off-grid environments.
