Li-ion Battery 18650

Li-ion Battery 18650, also named 18650 LiPo Battery, 18650 li-ion battery, is a cell 18mm x 65mm in size. The name refers exclusively to the size of the Li-ion Battery, but there can be minor variations even here. The Li-ion Battery 18650 has become the gold standard for replaceable and rechargeable Li-ion batteries.


Are 18650 Lipo?

No, 18650 batteries are not LiPo (Lithium Polymer) batteries. 18650 batteries are cylindrical lithium-ion batteries with a standardized size of 18mm in diameter and 65mm in length, hence the name 18650.

On the other hand, LiPo batteries are lithium-ion batteries packaged in flexible pouches or bags. Depending on the application’s specific requirements, they can be made in various shapes and sizes.

Although both 18650 batteries and LiPo batteries are rechargeable lithium-ion batteries, they have different characteristics and performance specifications that make them suitable for different applications. For example, 18650 batteries are often used in high-drain applications such as flashlights and laptops, while LiPo batteries are commonly used in remote control vehicles, drones, and portable electronics.

When we look at a Li-ion Battery 18650, secondary li-ion battery, or Li-ion Rechargeable Battery, the most important is the continuous discharge rating (CDR), also known as amperage capacity.

The Li-ion Battery 18650 offers the best performance of any consumer-grade rechargeable Lithium-ion battery;

18650 battery size or 18650 dimensions is easy to find according to its name; li-ion Battery 18650 is a cylindrical battery with a Diameter of 18mm, and a length of 65mm.

No matter what you name it, 18650 lipo battery or 18650 Li-ion Battery, it’s the same; many customers ask what’s the difference between the LiPo Battery and the Li-ion Battery; they are Lithium-ion polymer batteries.

Those Li-ion Batteries 18650 are not susceptible to damage from charging before fully discharged, though the Li-ion Battery 18650 degrades at about the same rate as your smartphone battery.
The Li-ion Battery 18650 isn’t a standardized cell; They’re not all built equally or with the same task.
