1. Lithium batteries have strong temperature adaptability. Solar street lights with lithium batteries can operate normally in environments ranging from -20°C to 60°C, and they can even function in extremely cold conditions of -45°C.
2. Solar street lights with lithium batteries are pollution-free and have a long lifespan. Lithium batteries are non-polluting, unlike lead-acid batteries which are contaminated with heavy metal lead. Additionally, the lifespan of lead-acid batteries is relatively short, whereas lithium batteries typically last over 10 years. The lifespan of the light-emitting diode (LED) source is also around 10 years.
3. Lithium batteries are smarter. With solar street lights using lithium batteries, intelligent optimizations can be made according to user needs, such as battery capacity, usage time, weather conditions, etc. This allows for efficient power level distribution and functionalities like light control, time control, and memory storage, ensuring continuous lighting for up to 10 days during rainy weather.
4. High energy density, lightweight, and easy installation.
Using solar street lights with lithium batteries saves time and energy due to their lighter weight, allowing them to be mounted on the opposite side of the panel. The energy density of lithium batteries can reach up to 460-600 Wh/kg, which is approximately 6-7 times higher than that of lead-acid batteries.
5. Solar street lights with lithium batteries are safer. Lithium batteries are dry batteries, and they are controllable, non-polluting energy storage solutions. They are more stable and safer compared to lead-acid batteries.
