What is 18650 lipo pil?

18650 Li-ion (Lithium-ion) battery cells are a popular type of rechargeable battery. They are widely used in various electronic devices such as laptops, flashlights, power banks, electric vehicles, and many more. The term 18650 refers to the physical size of the battery cell which is cylindrical in shape, 18mm in diameter, and 65mm in length.

The term LiPo (Lithium Polymer) is often used interchangeably with Li-ion, but they have different chemical compositions. LiPo batteries use a polymer electrolyte instead of a liquid electrolyte, which allows for a higher energy density and better packaging. However, LiPo batteries are more prone to swelling and overheating.

18650 Li-ion batteries have a nominal voltage of 3.7 volts and can range in capacity from 1000mAh to over 3500mAh. They can be recharged hundreds of times and have a long lifespan. However, it is important to use a compatible charger and handle them with care as they can be dangerous if mishandled.
