Technical FAQs 4
Why is a 21700 cell better than a 18650?
Industry Insight: Fewer cells reduce complexity and overall system weight while boosting performance; while earlier models used 18650 cells, new designs are increasingly adopting the 21700 format; superior energy density and thermal performance make it ideal for large-scale storage applications.
What is a 21700 battery?
A 21700 battery is a cylindrical lithium-ion battery (Li-ion). Its name comes directly from its physical size standard. It is the next step after the 18650 battery. The 21700 battery was made to meet the demand for higher energy density and larger capacity. Tesla and Panasonic first promoted this type.
Are all 21700 cells the same?
Not all 21700 cells are built the same. Some are optimized for high capacity (great for long runtime), while others are tuned for high discharge rates (better for power-hungry tools or drones). There’s a fun discussion I came across where hobbyists compared popular options.
What are the benefits of a 21700?
21700: Enables higher energy storage and supports robust, high-performance systems. - In-Depth Insight: As devices demand longer runtimes and more power, the 21700’s enhanced energy density not only extends operational time but also provides greater flexibility in system design.
