There are several types of lithium-ion chemistries that could be used within the 21700 format:Lithium Cobalt Oxide (LCO): High energy density but lower safety and lifespan.Lithium Iron Phosphate (LiFePO4): Safer with longer cycles but lower energy density.Nickel Manganese Cobalt (NCM): Provides a balance of energy density, cost, and safety.

[FAQS about What to use for 21700 battery cells]
21700 protected batteries have an electronic circuit. The circuit is embedded in the cell packaging (battery casing) that protects the cell from “over charge”, heat or “over discharge”, over current and short circuit. A 21700 protected battery is safer than an 21700 unprotected battery (less. .
A 3.7v a 5100mAh 21700 stores about 3 aH to max of 5 aH. It can store about 15 to 20 watt hours. A small air conditioning unit that can cool about 9000 BTU uses about 1100 watts per hour.. .
The way you recharge your battery impacts the life of the battery. If you can measure it, you want to deplete from 3.7v down it to about 3v. .
Recharge cycles vary and are limited. Think of it like a bucket. The trick is that the bucket also gets filled with other junk over time, so there is less room. As the battery is reused. [pdf]

XTAR's 6000mAh battery is currently the highest capacity 21700 on the market. In testing at a 500mA discharge rate (equivalent to 0.083C, calculated as 500mA ÷ 6000mAh), this cell has consistently delivered between 6100mAh and 6300mAh, making it an excellent choice for long runtime applications.

[FAQS about Super capacity 21700 battery cell]
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]
