lifepo4 battery calb 200ah 3.2v.What is a cylindrical 21700 lithium battery

　　Many friends have heard of 18650 batteries, but they may not have heard of cylindrical 21700. So what is cylindrical 21700? What are the advantages? If you are also interested in this topic, then follow the editor to read on. I hope that after seeing it, you can bring better help when selecting cylinder 21700.

　　Cylinder 21700 actually refers to a cylindrical battery with an outer diameter of 21mm and a height of 70.0mm. It is also quite common in our lives. In the future, everyone should know this when they see it. Currently, it is being used by companies in multiple countries such as South Korea, China, and the United States. So its scope of use is also very broad. And currently, there are two popular 21700 batteries on sale, namely 4200mAh and 3750mAh. In the future, when buying cylindrical 21700, everyone should distinguish it clearly. Then make a purchase after clarifying your actual needs. Of course, there is a larger 5000mAh (21700 lithium battery) that will soon be launched. The battery density of the cylindrical 21700 is currently the world's higher energy density and lower cost battery, and its price will be more affordable. It is widely used in fields such as power, energy storage, and home appliances and healthcare, such as two wheeled vehicles, tourist vehicles, AGV vehicle power batteries, and other places.

　　The manufacturer of cylindrical 21700 focuses on technological innovation as its core competitiveness, has in-depth and extensive cooperation with scientific research universities, and has its own testing room. The product here has a lighter weight and larger vehicle space. When using it, we should know that its monomers have a higher specific energy, so the number of battery monomers required for the same energy can be reduced by one-third. Therefore, this is also a major advantage of it. At the same time, it greatly reduces the difficulty of management and also reduces the number of metal structures and electrical accessories used in battery operation. Only in this way can it be applied in different industries. Furthermore, it greatly reduces the weight of lithium batteries. The specific energy of the entire vehicle will be partially improved. The cylinder 21700 can also significantly increase its energy when in use. The specific energy of the power battery system reaches 260 watts per hour/kilogram. Currently, the well done ones cannot meet this technical requirement. There is also a mature production technology process and quality assurance system here: ISO9001:2015 quality management system; Having professional design, application, quality control, delivery, and after-sales service capabilities.
