Designed for all-climate energy storage, INR21700-RH60 21700 cell stands out with extreme cold resistance down to -40℃. Different discharge cut-off voltages are set for sub-zero temperatures to protect cell structure. Its maximum continuous discharge current reaches 30A with 80℃ thermal cut-off. Low self-discharge and wide -20℃~25℃ long-term storage window greatly reduce inventory loss. Rigorous drop, crush and short-circuit tests ensure reliable performance under harsh working conditions.

Higher energy density
The 21700 cell offers greater capacity (typically 4000–5000 mAh) than the older 18650 cell, without a significant increase in size.
Improved power output
It supports higher continuous discharge currents, making it suitable for high-drain applications like e-bikes, power tools, and EVs.
Better thermal management
The larger cylindrical format allows for more efficient heat dissipation, enhancing safety and cycle life compared to smaller cells.
Cost-effective performance
Fewer cells are required to achieve the same pack capacity (e.g., replacing 3-4 18650 cells with 2-3 21700 cells), reducing assembly complexity and overall system cost.
