There are a few different types of lithium-ion cells that are popular for use in custom battery packs. The most common type is the 18650 cell, which is a cylindrical cell that is 18mm in diameter and 65mm long. These cells are often used in laptop batteries and other high-powered applications.
Another popular type of lithium-ion cell is the 26650 cell, which is slightly larger than the 18650 cell. These cells are often used in high-powered applications such as electric vehicles.
The third type of lithium-ion cell that is popular for use in custom battery packs is the 21700 cell. This type of cell is similar in size to the 18650 cell, but it has a slightly larger diameter and length. These cells are often used in high-powered applications such as electric vehicles.
Many lithium ion cells are in short supply, so it is important to choose the right one for your custom battery pack.
Lithium ion cells are generally divided into three categories - high power, high energy and balance.
Engineers often ask us which lithium-ion cell is the most popular for custom battery packs. The answer really depends on the application, but below are some of the most popular lithium-ion cells.
If you're looking for advice on which cell is best for your application, contact one of our battery designers. We'll analyze your mechanical and electrical needs and choose the finest battery based on your specifications. Please schedule a free consultation here. If you've already chosen a cell, we can design the BMS as well as the mechanical enclosure.
