Power lithium-ion batteries refer to lithium-ion batteries with a capacity of more than 3AH, and generally refer to lithium-ion batteries that can be discharged to drive equipment, instruments, models, vehicles, etc. Due to different users, the capacity of the battery may not reach the level of unit AH. As a type of secondary battery, power lithium-ion batteries have the common characteristics of other secondary batteries: they can be charged and discharged multiple times, and can be reused repeatedly. Overall, the use of power batteries has gone through lead-acid batteries, nickel cadmium batteries, nickel hydrogen batteries, and lithium batteries, and ultimately developed towards newer types of batteries such as fuel cells. And the working voltage of the battery is high, the specific energy is large, the volume is small, the weight is light, and the cycle life is long
