They have several advantages, including: (i) the limitless energy storage capacity that is proportional to the size of the electrolyte storage tank size, (ii) a scalable power output that is independent of energy capacity, because it is solely a function of the number and size of stacks, (iii) contamination resistance, because both the anolyte and catholyte are made of vanadium, (iv) a superior health profile, because of the harmlessness of reasonably low concentrations of vanadium, and also because vanadium redox couple reactions do not generate toxic gases or vapours, (v) superior safety—VRFB has a low risk of explosion, unlike other rechargeable systems such as lead-acid and Li-ion, and (vi) modularity, where several stacks can be juxtaposed and coupled into a cluster of several compartments.

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 before you recharge. If you are not sure, use the device until it indicates a battery. .
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. A 21700 battery usually takes 1.5 to 4 hours to charge. Charging time depends on the battery capacity and charger speed. Fast chargers can charge quickly but may affect battery health. [pdf]
