2.Why 21700 Battery Cell?

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.
