Common Questions 11.1V 10000mAh Battery Pack Answers
Are your 21700 batteries certified?
CMB’s batteries have UL, FCC, and CE certificates. CMB has sufficient certificate registration experience, if you need other certificates, please contact us.
Can the battery operate in low temperatures (e.g., -20°C)?
Yes, it supports a wide operating temperature range from -20°C to 60°C.
Is it possible to customize the casing, waterproofing, or low-temperature performance?
Yes. We offer customization based on your specific requirements, including waterproof designs, heating functions, and low-temperature operation (as low as -20°C). We also provide custom BMS configurations and communication protocols such as CAN, SMBus, and RS485 to ensure compatibility with demanding or outdoor environments.
What are the dimensions and weight of the battery pack?
Since we use 21700 cells, the pack is more compact and has a higher energy density. Exact dimensions and weight will depend on the selected housing and BMS configuration. We can provide detailed specifications after reviewing your technical drawings.
Is it possible to produce samples or in small quantities?
Yes. We provide a flexible MOQ, which includes small-batch customization and sample orders for prototype testing.
