1. The working voltage of the single battery of the power lithium-ion battery is as high as 3.7V, which is three times that of the nickel-cadmium battery and the nickel-hydrogen battery; the lead-acid battery is nearly twice that, which is also an important reason for the higher energy of the power lithium-ion battery.
2. Power lithium-ion batteries are generally encapsulated in aluminum shells, which have the characteristics of small size, light weight, strong power, no memory and green environmental protection. They have been widely used at present.
3. It can charge and discharge quickly with large current of 2C. The battery can be fully charged within 1.5 minutes at 1.5C under a special charger. The starting current can reach 2C, but lead-acid batteries do not have this performance.
