Recently, as a pollution-free, fast energy storage, lightweight and convenient alternative battery, lithium battery solar street lamp has attracted more and more attention. The service life of large capacity lithium battery is more than 5-8 years, and its self discharge rate is extremely low, the discharge voltage is gentle, and the charge is fast. It has gradually been used in Taiyang street lamps. This kind of lithium battery solar street lamp has blossomed on the trunk roads of China.

However, the lithium battery solar street lamp is three times more expensive than the traditional battery. Generally, the price of a 6 meter 30 watt street lamp with 32ah lithium battery is about 1500, and the lithium battery is easily affected by external forces. However, in terms of later maintenance, the external lithium battery must be much easier than the gel battery buried in the frozen soil. In addition to the advantages in basic characteristics, lithium batteries can actually bring their maximum value into play in most places with poor sunshine in the south, especially in rainy and rainy days. This is because lithium batteries have stronger charging capacity than other batteries in weak light. It is believed that with the development of science and technology, the disadvantages of lithium batteries will be gradually eliminated. The manufacturers of lithium battery solar street lamps believe that the above is the reason for the high price of lithium battery solar street lamps
