12 Volt 24 Volt Solar Street Light Lithium Battery IP67 Long Service Life

Description of Battery Used In Solar Street Light

As the solar street light lithium battery technology is becoming more and more mature, the capacity is getting larger and larger, the life span is getting longer and longer, and the scope of application is getting wider and wider. Now the use of solar street light lithium battery has been carried out to the solar street light industry, replacing the lead-acid and gel batteries. The installation saves time and effort. If the lead-acid battery pack, need to be buried in the ground near the light pole, placed in the buried box, and if the use of lithium batteries, with its lighter weight, can be hung to the back of the battery plate, saving time and effort.

Battery Used In Solar Street Light Features

• Solar street light lithium battery has longer life. The annual loss of the lead-acid battery is high, while the lithium battery has a long service life, which is normally able to all warranty for three years.

• Solar street light lithium batteries are safer, no memory effect. Lead-acid batteries easily into the water, lithium batteries are not easy to enter the water. And lead-acid batteries are with memory, is not fully discharged when charging will occur memory effect, will affect the life of the battery.

• Modular installation: Modular installation, expandable battery capacity, simple structure, easy to install and maintain.

• Low temperature protection function: Low temperature protection function, minimum -40℃ environment works normally.

• Solar street light lithium battery has high energy density. Solar street light lithium batteries have high storage energy density, which has reached 460-600Wh/kg, is about 6-7 times that of lead-acid batteries. This will be better energy storage for solar street lights.

Battery Used In Solar Street Light Advantages

• Fast charging speed: more than 1.5 times the charging speed of ordinary batteries.

• High depth of discharge: the depth of discharge can reach at least 80% or more.

• Simple installation: the solar street light lithium battery is small in size and light in weight for easy installation

• Integrated Design: The controller can also be placed outside, simply leaving two cables outside, one connected to the solar panel and the other to the light, making the assembly work easier.

• Waterproof Aluminum Alloy Shell: The solar street light lithium battery is used outside, so we have to adapt to all kinds of weather. Here we use IP67 aluminum alloy shell, which is waterproof, collision-proof and fire-proof to ensure adequate battery safety.

Production Process

• Capacity separation of lithium battery cells: All cells should be divided for the second time to ensure the full capacity of the battery.
• Battery pack: The internal resistance and voltage of the battery core are paired in groups to ensure that all internal resistance and voltage of the whole battery pack are consistent, and the products with higher safety and quality can be achieved
• Bracket combination: The battery pack adopts the safest bracket combination, so the heat dissipation effect of the battery pack is better and more reliable.
• Battery spot welding: Spot welding with pure nickel sheet has the advantages of small internal resistance, large over-current and no heating.
• Battery management system: Highland barley paper is used for insulation protection and safety protection when the battery is connected; The protection board has the functions of overcharge protection, over discharge protection, over-current protection and balance protection; It has no memory effect and can be charged and discharged at any time
• Aluminum alloy shell packaging: The battery pack is packed with IP67 aluminum alloy shell, which not only makes the appearance beautiful, but also makes the safety protection of the battery not to be ignored.
• Battery test: Battery aging test, charge discharge cycle test, we guarantee to do the best quality to customers.
