Why do solar street lights choose lithium batteries?

The solar energy street lamp has a good energy-saving advantage, which makes it widely used. There are three types of solar cells in the solar street lamp, namely lithium battery, lead-acid battery and gel battery. Among them, the lithium battery has obvious advantages.

1, lithium battery is more secure:

Lithium battery is a dry battery type, and it is a storage battery with controllability and pollution-free. It is more stable and safer than lead-acid batteries.

2. Intelligent optimization calculation and reasonable distribution of electricity consumption level:

The solar street lamp lithium battery can also intelligently optimize the calculation of the remaining capacity of the battery, the length of day and night, the weather conditions, etc. according to the user's needs, rationally allocate the power level, and realize the functions of light control, time control and storage memory, which can ensure at least ten days. The lights are on continuous rainy days.

3, better durability:

Lithium batteries are more durable, consume less, charge and discharge more than 500 times, and have no memory. The general life expectancy is 4-5 years. Durability: Lead-acid batteries are generally deep-charged and deep-discharged within 300 times. They have memory and have a life span of about two years. And there is liquid in the lead-acid battery. After using it for a period of time, if it is found that the battery is hot or the charging time is short, you need to replenish the liquid.

4. Battery capacity:

Lithium battery capacity is 8-10 amps, lead acid battery capacity is 20 amps

5. Volume and quality:

Lithium batteries are generally 2.5-3 kg, and the volume is relatively small, so the ride is light and convenient to carry. : The weight of a general lead-acid battery is 16-30 kg, which is relatively large.
