Best Battery For Solar Power Street Lamp

Solar power street lamps are currently developing relatively rapidly, and have gradually replaced some traditional street lights in rural and urban areas. The solar power street lamp is an independent lighting system composed of light source, battery, solar panel, controller and other accessories. The battery is the core accessory of solar power street lamps. There are four commonly used batteries for solar power street lamps, namely ternary lithium batteries, lithium iron phosphate batteries, lead-acid batteries and gel batteries. Among the four types of batteries, lithium iron phosphate batteries are more cost-effective.

1. With high storage energy density, small size, easy to transport

Compared with other batteries, the energy density of lithium batteries is very high, currently reaching 460-600Wh/kg, which is about 6-7 times that of lead-acid batteries. This means that under the same charge capacity, the weight of the lithium battery is lighter. According to calculations, the weight under the same volume is about 1/5-1/6 of the lead-acid battery. Lithium batteries are much more delicate and lighter than lead-acid batteries, and they are very convenient for transportation and installation.

2. Lithium battery has longer service life

Unlike lead-acid batteries that need to be replaced in two or three years, the service life of lithium batteries is generally greater than 10 years. While in solar power street lamp systems, the service life of LED light sources is generally up to 10 years (about 50,000 hours), and lithium batteries are perfect It is matched with the lighting system, eliminating the tedious process of frequent battery replacement.

3. Lithium battery has better anti-theft performance

The power of solar power street lamps mainly comes from the energy storage of batteries, so the cost of the battery is slightly more expensive, which will attract some thieves. In the past, lead-acid batteries were buried in the ground and could easily be dug away by thieves. However, the lithium battery is installed under the solar panel. Because the height of the road solar light pole is high, it is more difficult to steal the lithium battery. If you install a special battery anti-theft box for the lithium battery, it will be more able to prevent the battery from being stolen.

4. Lithium batteries have less pollution than lead-acid batteries

We all know that lead-acid batteries have a relatively short service life. Although they are cheap, they may need to be replaced once a year, which will greatly increase environmental pollution. Moreover, lead-acid batteries are more polluting than lithium batteries. If the battery needs to be replaced all the time, it will cause continuous damage to the environment.

5. Easy maintenance

Solar power street lamps only need to take out the battery from the light pole or battery panel when repairing, while traditional solar power street lamps need to dig out the buried battery when repairing.

6. Lithium batteries are safer

Lithium battery is dry battery. It is a controllable and pollution-free energy storage battery, which is more stable and safer than lead-acid batteries. Lead-acid batteries are easy to enter water, and lithium batteries are not easy to enter water. And if the lead-acid battery is charged when it is not fully discharged, it will have a memory effect, which will affect the service life of the battery. The lithium battery can be charged at any time, so it is safer to use.

EXC-CR-Z01 all in one integrated solar power street lamp use the lithium iron phosphate battery. With this high performance rechargeable battery, the solar light can provide high efficient illumination. Now lithium batteries are more and more widely used, with high performance in the market Basically all solar power street lamps use lithium batteries. solar power street lamps using lithium batteries will be relatively more expensive. If the budget is limited, you can also choose street lights equipped with other batteries.
