Why choose lithium phosphate battery for solar street light battery？

With the wider application of new energy street lights, we found more and more solar street light manufacturers. Many manufacturers just produce purely and do not have too many technical patent reserves. According to experience, they still use 12V gellead-acid batteries or ternary12V lithium batteries. Gel battery is bulky and has less service life than 12v 42ah Lifepo4 Battery . Although ternary 12v 42ah Lifepo4 Battery has high energy density and long service life, its safety is arguable. Therefore, we, Spaceflightlithium polymer battery is currently used as the battery for solar street lights. Because under the current market technical conditions, we believe that a lithium phosphate battery is the most cost-effective 12v 42ah Lifepo4 Battery , not only safe but also the service life and price can reach our expected results. Let me explain the reasons why a lithium phosphate battery is used as a solar street light battery:

1. The battery has no balance problem, and the life span can be more than 15 years

Because the outdoor environment 3C discharge intensity is designed to be “rooted.” Turning to the street light, there is only a charging intensity of 0.1-0.3C, and there is no problem with using the solar street light battery for 5 years.

2. The controller and the light bead are directly connected together, which greatly improves the reliability. Therefore, the operator of installation only needs to plug in the DC plug.

3. Low-light power generation is much better. Photovoltaic street lights can only be done well on sunshine days. The key is the power generation on low-light rainy days. The reason is very simple. The photovoltaic effect relies on the intensity of light to generate an electromotive force (voltage). Which of the 12V battery and 3.2V battery panels generates more power on rainy days?

4. Looking at the composition and structure of thelithium polymer battery, you know that the iron-lithium battery has no heavy metals and scarce resources, and it will definitely become a cheap and clean energy storage battery. Cobalt in ternary lithium is very scarce, and cobaltate has tripled last year alone.Sometimes, lithium car battery can also play an important role.Sometimes, the lithium battery price is also a very important factor.

In the end, many people will ask that everything has its two sides, then I will also talk about the shortcomings of a few lithium phosphate batteries.

1. The wiring really needs to be thick, and we even use military-grade plugs.

2. The requirements for supply chain management and production equipment are very high. For example, iron-lithium producers usually start as listed companies, with capital and quantity thresholds; Full parallel connection places high requirements on LED suppliers.

3. The above points, to sum up as the demands for the low failure rate, long life, and high-cost performance are the real pain points of the photovoltaic street light industry for many years. The practice of this light proves and is convinced that the choice of alithium phosphate battery is the future. At present, more and more street light counterparts are choosing the technology path oflithium polymer battery.Sometimes, the lithium battery price is also a very important factor.

4. Exposure to direct sunlight during the day for a long time, the high temperature generated may cause serious failure of the lithium battery. This is primarily as a result of the operative temperature vary of typical atomic number 3 batteries is -20°C to -60°C. however the interior temperature of the box once direct daylight is also on top of 80°C. Extreme close temperature may be a massive killer for atomic number 3 batteries.

5. Because solar street light tubular battery need to be installed outdoors, even in the wilderness away from the crowd. There are certain difficulties in management. What’s more, inadequate management will result in issues that can’t be detected within the early stage, however eventually, become serious and expand.
