What are the important uses of 18650 batteries? 

18650 lithium batteries are more stable and sturdy in the international market, and their market share is also ahead of other lithium-ion battery products. It has been widely used in the large, medium, and small lithium battery industries such as digital technology electronic equipment, mechanical equipment, and medical machinery. It has also been widely used in the energy lithium battery industry such as service robots, AGV trucks, unmanned aerial vehicles, and new energy vehicles. It is widely used in intelligent machines, tablets, laptops, electric toy cars MP3/MP4、 Mobile phone headphones, mobile chargers, model airplanes, mobile phones and other aspects have shown strong development prospects. The characteristics of 18650 lithium batteries include stronger cycling characteristics in terms of volume and safety factor balance compared to individual lithium cobalt oxide raw materials. 

Due to technical reasons, its early nominal voltage was relatively limited and its utilization scope was also limited. With the gradual development of the secret formula and structure, the nominal voltage of rechargeable batteries has already reached, and their capacity has already reached or exceeded the level of lithium cobalt oxide batteries. So initially, most people preferred to use 18650 lithium battery packs.
