1. High voltage and light weight of lithium battery. The average voltage of a single cell can reach 3.7V or 3.2V, which is equal to the series voltage of 2-4 NiMH batteries or nickel isolated batteries. If the customer requests to use the battery voltage to pass the customs, then it is easy to choose the lithium battery to form a lithium battery group, which is convenient and quick to increase the voltage of the lithium battery.

2. The energy and density of lithium battery are also very high for other batteries. Lithium battery has a high energy storage density, and the density of commonly used lithium battery can reach 450-620wh / kg, which is 5-7 times of that of lead-acid battery. If people choose batteries, they will also consider a very important problem, which is pollution.

3. Compare the battery weight. A lithium battery weighs about five to six times as much as a lead-acid battery. Although the weight of lithium battery is not much different from that of polymer lithium battery. But looking at capacity and life span, people will choose lithium batteries.

4. The service life of lithium battery is very long. If there is no accident, the service life of a lithium battery can be more than 6 years, up to 9 years. The normal use times are more than 1000. If there is no accident, the number of times of use can reach more than 1500.

5. Low self discharge and no memory effect. In the production of lithium battery, adding a protective plate to the lithium battery can make the lithium battery have the effect of overcharge and overdischarge. The lithium battery itself has high power bearing capacity. The lithium battery selected by the electric vehicle can achieve the high-efficiency response capacity of 15-30c charging and discharging, so as to accelerate the high-intensity start of the vehicle.

6. The lithium battery is green and environmentally friendly. The lithium battery does not contain lead, mercury or cadmium.
