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.

[FAQS about What accessories do you need for a 24 volt lithium battery pack]
A battery does not necessarily need an inverter to function, but an inverter is typically required if you want to power AC devices from a battery, as batteries store DC electricity2. While inverters can operate without a battery, they function more effectively when connected to one, especially in off-grid situations3. It is advisable to connect your inverter to a battery to store generated energy, but it can also operate without one when connected to a continuous power source4. [pdf]
