HB3 battery cell 21700

Why should you buy a 21700 battery?

This increase in size allows the 21700 to deliver higher energy storage and improved performance. The larger size of the 21700 cell enables it to store more energy, making it ideal for applications requiring high power capacity, such as electric vehicles and industrial battery packs.

Are 21700 batteries based on lithium ion?

However, most 21700 cells are based on lithium-ion (Li-ion) technology, which is widely used across many types of rechargeable batteries due to its excellent energy density and long lifespan. There are several types of lithium-ion chemistries that could be used within the 21700 format:

How much does a 21700 battery weigh?

Tip: When selecting a 21700 battery, consider the specific chemistry to match your application’s energy and cycle life requirements. The 21700 cell weighs approximately 60–70 grams, depending on the manufacturer and specific chemistry.

What is the difference between a 21700 and a smaller battery?

One of the standout features of the 21700 is its higher capacity and energy density compared to smaller batteries. This allows it to power larger devices, such as electric vehicles and solar energy storage systems, with more reliable performance and fewer recharges. As mentioned earlier, the 21700 battery is 21mm in diameter and 70mm in length.
