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]

The cans for the 18650 and 21700 are made from nickel plated steel and deep drawn in a two-stage process. The result is the base of the can is thicker than the cylindrical side wall. 1. 18650 1.1. Base thickness ~0.3mm 1.2. Wall thickness ~0.22 to 0.28mm 2. 21700 2.1. Base thickness ~0.3. .
Cylindrical cells are used in numerous applications and cooling varies from passive through to immersed dielectric cooling. The diameter, length and connection of the. .
Cylindrical cells are designed with a number of safety features including a defined vent path/weakness. The capacity is relatively small and hence the electrical and thermal energy. The 21700 battery is a Li-ion battery named after its 21mm × 70mm cylindrical size (diameter × height). When compared to AA size and 18650 type cells, their height and diameter both are larger. [pdf]
