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. High-performance 21700 7.4V 5000mAh lithium battery pack in a 2S1P configuration, designed for smart devices and power tools. Reliable energy solution by Topwell Power. [pdf]

Lithium titanate battery (LTO) outperformance in fast charge (5C-30C), longer battery life (>7000cycles), wider working temperature (-40°C-70°C) and excellent safety compared with other carbon-based lithium battery. [pdf]
[FAQS about Lithium titanate battery pack high power]
The size of a UPS (Uninterruptible Power Supply) is determined by its power capacity (measured in volt-amperes, VA, or watts, W) and battery runtime.When sizing a UPS, consider the intended load, which is the combined voltage and amperage of all connected devices1.The capacity indicates the maximum power output the UPS can deliver1.The runtime refers to how long the UPS can supply battery power during an outage3.For specific dimensions, you would need to refer to the specifications of individual UPS models, as sizes can vary widely based on their design and intended use4.
