21700 batteries offer several advantages over their predecessors: Higher Energy Density: Their larger size allows for a higher capacity, providing extended runtime for devices. Longer Cycle

21700 batteries are larger and offer higher capacity than 18650 cells, which allows for fewer cells per pack and increased runtime in high-demand systems. Do 21700 battery cells require specific holders or enclosures? Yes. Due to their size, 21700 battery cells must be used with holders and hardware designed specifically for the 21mm x 70mm format.
The 21700 cell stands out due to its standardized dimensions of 21mm in diameter and 70mm in length. These measurements make it larger than the widely used 18650 cell, which measures 18mm by 65mm. This increase in size allows the 21700 to deliver higher energy storage and improved performance.
