The most obvious advantage of using 21700 compared to 18650 is that it has a higher energy density, which means that in a battery pack with specific dimensions and a particular power output, fewer batteries are used, which helps to cool the battery pack as well as possible. Also, electric car factories like Tesla use 21700 batteries in their products. The …
