u003cpu003eu003c/pu003eu003cpu003e   Due to the fixed size of the 18650 battery, its maximum capacity has always attracted the attention of many practitioners. In recent years, various manufacturers have improved their technology and their capacity has increased accordingly. Samsung, Panasonic, LG, Sony and Toshiba can achieve more than 3600mAh, but the best stability and consistency is the capacity range of 2600~3000mAh. If it is a battery pack, it is best not to use the highest capacity, regardless of the cost performance and the service life of the battery pack. It is not very cost-effective, so it is not to say that the higher the battery capacity, the more stable and long-term use. u003c/pu003eu003cpu003e  The battery pack needs to be customized according to the product. If the product is mid-to-high-end, the battery can be imported from big brands (original), because there are many small domestic battery factories that have false standards. If you are too price-sensitive (such as high price competition for strong light flashlight products), you can choose 2200mah~2600mAh batteries from domestic regular manufacturers or a lower 1500+ capacity. Most application fields have different current and time requirements, so most power supply batteries are presented in battery packs. When choosing a battery pack, you should consider the consistency, stability, and safety of the battery cells. These indicators are very important. . u003c/pu003eu003cpu003eu003c/pu003eu003cpu003e   It is worth noting that many buyers will have a misunderstanding that the capacity is high, the actual discharge current will be large, but this is the opposite: 18650 lithium batteries are generally divided into capacity Type and rate type, the capacity type mainly reflects the large capacity, but the discharge current is generally lower than 1C, and the current is small; the rate type can discharge at a large current, but the capacity is lower, and the use time is not long. This is similar to not having both fish and bear's paws. u003c/pu003eu003cpu003e  How can I know the actual capacity of the 18650 lithium battery pack? The labeled capacity of unscrupulous manufacturers is unbelievable. If you want to know the actual capacity, you have to perform charge and discharge tests with professional testing and testing equipment. Therefore, most people don’t know the specific capacity when they get it. It is easy to be deceived by the seller. Buyers do feel that the capacity is strange, and they can ask the supplier to issue a test report or choose a third-party professional test agency report. u003c/pu003eu003cpu003e   Finally, the price of 18650 lithium battery pack is proportional to the capacity. The larger the capacity, the greater the energy ratio and the more raw materials used, so the price will be more expensive. The general price is 10~30 yuan/piece. u003c/pu003eu003cpu003eu003c/pu003eu003c/pu003e
