Technical FAQs 4

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.

What is a 21700 battery pack?

If you’ve been around anything that runs on lithium batteries—whether it’s drones, e-bikes, power tools, or even flashlights—you’ve probably noticed the buzz around 21700 battery packs. The name comes from the size: 21 mm in diameter and 70 mm in length.

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 an unprotected 21700 battery?

Unprotected 21700 Batteries: Designed for battery packs or high-performance applications where external battery management systems (BMS) handle protection. 21700 batteries are becoming the industry standard for devices requiring longer runtime and more power. Some common applications include:
