The highest capacity 21700 is the XTAR 21700 6000mAh. The closest runner-ups are Vapcell's F60 (6000mAh) and BAK's 5.5Ah (5500mAh) cell. The XTAR 6000mAh cell is not particularly hard to come by, but it is relatively expensive at over $15 per cell. [pdf]
[FAQS about Capacity up to 21700 cells]
The 21700 battery is a rechargeable lithium-ion battery with a cylindrical shape, measuring 21 mm in diameter and 70 mm in length. It has a nominal voltage of 3.6V to 3.7V and is increasingly popular for its higher capacity, making it ideal for high-drain devices like flashlights. [pdf]
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]
