The lithium battery has small volume and light weight, and the device saves time and labor. At present, the choice of global solar street lamps is generally integrated street lamps. If lead-acid battery pack is used, it needs to be buried underground around the lamp pole and placed in the buried box. If lithium battery is used, with its lighter weight, it can be externally hung on the back of the battery panel, saving time and effort.

Lithium battery has less pollution than lead-acid battery and is green. The service life of lead-acid battery is relatively short. Although it is cheap, it may have to be changed once a year, which will greatly increase the pollution to the environment. And lead-acid battery itself is more polluted than lithium battery. If it is always replaced, it will always cause harm to the environment. Lithium batteries are not polluted, while lead-acid batteries are polluted by heavy metal lead.

Lithium battery: there is no doubt that it is superior to lead-acid battery in all performance aspects. At present, lithium iron phosphate battery is common. This battery does not have memory effect like lead-acid battery. After more than 1600 times of charging, the storage capacity of this battery can still reach 85%. Compared with lead-acid battery, lithium battery has the advantages of light weight, large capacity and long service life.
