21700, 18650, 20700, and others simply refer to the physical size of the lithium-ion cell. For 18650, it’s an 18 mm diameter x 65 mm length. 21700 is 21 mm x 70 mm. While the explanation is simple, the difference is profound. It’s easy to see with a quick volume calculation. 18650. .
The most obvious benefit of going with 21700 vs 18650 is that the extra density means there’s more available energy in them to run your tools and gear longer. Batteries that we see. .
Batteries like the Bosch Core18V, Milwaukee M18 High Output, and Metabo LiHD packsdo more than just take advantage of longer. [pdf]
