Because it is a relatively mature lithium-ion battery, all aspects of the system quality stability is good, widely used in about 10 kilowatt-hours of battery capacity occasions, for example, in, in mobile phones, laptops and other small electrical appliances.
21700:
This battery measures 21mm in diameter and 70mm in length and is becoming increasingly popular in the market.
Because of its volume increase, the space utilization rate becomes larger, the cell monomer and the system energy density can be improved, its volume energy density is much higher than the 18650 type battery, widely used in digital, electric vehicles, balance vehicles, solar energy lithium ion battery street lamp, LED lights, power tools and so on. The production of such battery manufacturers are Tesla, Samsung, Panasonic, BAK, Lion new energy, etc.
32650:
The battery measures 32mm in diameter and 65mm in length. It offers even higher capacity and power output, making it suitable for applications that demand extensive energy storage and discharge capabilities.
26650:
The battery measures 26mm in diameter and 65mm in length. Nominal capacity of 3200 mAh, It provides a larger capacity and higher power output, this kind of battery has excellent capacity and high consistency characteristics, has gradually become a replacement of 18650 battery trend, in the power lithium battery many products will gradually favor this.
Pros and cons of cylindrical lithium ion battery

The process of cylindrical battery is relatively mature. Cylindrical lithium-ion batteries have been improving daily, and continuous development and improvement ensure their long-term usage.
Cons:
Excessive heat may create inflammability chances. It can lead to gas release and a fire or explosion. So these batteries need extra care and protection for their users.
After the cylindrical lithium battery group, the gap is relatively large, occupying space.
Due to the poor consistency of the bottom spot welding structure, small batteries are mostly in parallel, and BMS is not easy to manage.
The energy density increases in a small space
Difference between cylindrical and prismatic lithium-ion battery
The major differences between both batteries are as under:
● The shape of cylindrical lithium batteries are cylindrical and are made with metal casing, and lithium prismatic cell have a rectangular or square shape.
● Cylindrical batteries have an electrode core surrounded by an electrolyte and separator. In contrast, prismatic batteries have their laminated structure designed with multiple layers of electrodes and separators stacked together.
● Prismatic batteries provide high energy density and large capacity that prioritize long runtime. In comparison, cylindrical batteries don’t offer large capacity.
● The shape of cylindrical lithium battery is higher, can be composed of a variety of sizes. The square battery is a little bit more limited.
How many cylindrical batteries does a motorcycle lithium battery require?
The number of cylindrical batteries required for a motorcycle lithium battery depends on various factors, including the desired voltage and capacity of the battery and the specific requirements of the motorcycle.
Two points are important when deciding on cylindrical batteries for motorcycles.
