Why Choose Solar Lithium-ion Batteries Instead of Lead-acid Batteries when They Are Also Energy Storage Batteries?

The same is the energy storage battery, why choose lithium-ion batteries rather than than lead-acid batteries?
The first thing we must know is that compared to lead-acid batteries, lithium-ion batteries are a controllable, non-polluting energy storage type of battery, the new lithium-ion battery solar street lights can be well matched with the system. As lithium-ion battery technology becomes more and more mature, the capacity is getting bigger and bigger, the life span is getting longer and longer. Now the use of lithium-ion batteries has been carried out to the solar street light industry, replacing the lead-acid and colloidal batteries.

Nowadays, the first choice of global solar street light is generally integrated street light. If a lead-acid battery pack is used, it should be buried in the ground around the light pole and placed inside the buried box. If lithium-ion batteries are used, by virtue of their lighter weight, they can be hung outside on the opposite side of the panel, saving time and effort.

We all understand that the service life of lead-acid batteries is relatively short, and although it has the advantage of being cheap, it may have to be replaced once a year, which will greatly increase the pollution to the environment.

Now, lithium-ion batteries are becoming more and more intelligent. Lithium-ion batteries can be adjusted according to the user's needs, the length of use, etc. Many lithium-ion batteries can be installed with a BMS management system, and you can even view the status of the battery in real time on your cell phone. It can be able to independently detect the current and voltage of the battery. If there is an abnormality, the BMS system is able to adjust automatically.

Lithium-ion batteries have a life of 35 years and are generally able to guarantee three years. The cycle life of lead-acid batteries is about 300 times. And lithium-iron phosphate ion batteries, 3C cycle life in more than 800 times.
Lithium-ion batteries have a very high energy storage density, which has now reached 460-600Wh/kg, about 6-7 times that of lead-acid batteries.

Solar street lights are exposed to sunlight every day, so there are high requirements for the temperature environment. Lithium iron phosphate batteries can reach a thermal peak of 350-500 ℃, can be used in -20 ℃ - 60 ℃ environment.
The current mainstream battery on the market is 48 volts, if replaced, lead-acid batteries about 450 yuan, the warranty period of one year; lithium-ion batteries are relatively expensive, to about 1,000 yuan, but the warranty period of two years.

Sum up: the advantages of solar lithium-ion battery street lights.

1. Adjustable solar panel bracket to collect maximum light.
2. green environmental protection.
3. Lithium-ion batteries are easy to install, directly under the solar panel, small size, light weight, reducing construction cost costs.
4. Long service life, 3-5 times that of traditional energy storage lead-acid batteries.
5. High and low temperature resistance can be used in -20℃-60℃ environment, special process can be used in -45℃ environment.
6. Good maintenance-free performance.

Lithium-ion battery solar street light has become a development trend, the future choice of lithium-ion batteries as energy storage devices for solar street lights will be prevailed.
