What are Li Ion 18650 batteries?

18650 batteries are a type of rechargeable lithium-ion battery. The name "18650" comes from the battery's dimensions: 18mm in diameter and 65mm in length.

These batteries are commonly used in devices that require high-capacity power, such as laptops, flashlights, and electric vehicles. They are also popular in the vaping community for use in vape mods.

18650 batteries typically have a nominal voltage of 3.7V and a capacity ranging from 1200mAh to 3500mAh. They can be recharged hundreds of times before their performance begins to degrade, and are known for their high energy density, meaning they can store a lot of energy in a relatively small size.

It's important to note that 18650 batteries should only be used with compatible devices and chargers, as they can be dangerous if not handled properly.
