Which lithium battery is good? How to choose?

First of all, it depends on where you use the battery. Because the objects used are different, the performance requirements for lithium batteries are also different. Second, it depends on the environment in which you use the battery. The lithium batteries used in the south and the lithium batteries used in the north also have different requirements. The important application scenarios of application lithium batteries are divided into two categories: power source type (power source type) and energy storage type. Such as electric bicycles, electric tricycles, electric forklifts and other special vehicles, electric vehicles, etc. In particular, electric forklifts and electric vehicles have higher requirements for charging and discharging lithium batteries. Lithium batteries sometimes have to reach a discharge rate of 3-5c during use. Application scenarios of energy storage type include base stations, power plant DC screens, stadiums, etc. This use scenario requires a high-energy-density lithium battery. The operating environment is in our country, and the temperature difference between north and south is great. The temperature in the south reaches about 40 degrees Celsius in summer, while the temperature in the north reaches minus 40 degrees Celsius in winter. The performance requirements of lithium batteries in these two environments are also different. In the South, we want lithium batteries with good high-temperature performance. In the north, lithium batteries must have good low temperature performance. Battery raw materials Currently commonly used lithium batteries include three materials: lithium manganese acid and lithium iron phosphate. These three materials have their own characteristics. The voltage range of lithium manganate battery is 3-4.2v, which has higher and lower temperature performance than lithium iron phosphate, but has a lower cycle life. The voltage range of lithium iron phosphate batteries is 2.5-3.65v. Long cycle life. The ternary battery uses the same voltage range as the lithium manganate battery. But the energy density is the highest, the disadvantage is the lowest safety performance. It is easy to catch fire or even explode. The basic requirements of battery screening. In the monomer screening of lithium batteries, it is important to investigate the voltage consistency, capacity consistency and internal resistance consistency of several indicators. Part of the battery charging and discharging platform is used as a reference indicator. In summary, I think the most important thing in choosing a lithium battery is safety. Besides, the best battery for you is good. I hope it can help. Which of the lithium battery or the lead-acid battery electric vehicle is better does not mean that it runs far. The key depends on the capacity of the battery. It is meaningless to say who is far away. For example, they are both 48V20AH. Lithium is basically the same as lead acid because it has the same capacity, but lithium is lighter, so it is a bit farther than lead acid. It can also be extended. Two people, one for 90 kilograms and one for 150 kilograms, use the same battery to drive the same car. A 90 kilogram person can run far. After all, there are more than 60 kilograms of fat, haha. But if lithium is 48V10AH and lead acid is 48V20AH, then lead acid is far away. Simply put, lithium is lighter than lead acid and can also be discharged.
