In solar street light system: Solar panels convert sunlight into electricity, which is stored in rechargeable batteries for LED lighting. The choice of battery plays a vital role in the effectiveness of solar lights.

The type of battery commonly used in Solway solar lights is lithium iron phosphate cube batteries. Lithium iron phosphate cube batteries are praised for their excellent performance, small size, fast charging, long life and stability. They can be charged and recharged up to 5,000 times, have a service life of up to 8-10 years, and have a wide temperature range, which can work stably from -40℃ to 70℃.

In addition, there are several other commonly used types of solar cells on the market, including lead-acid batteries, gel batteries and ternary lithium batteries, which are outdated and basically eliminated by the market.

The current mainstream choice of solar street lights:

Small household solar lights: mostly use nickel-metal hydride batteries (low cost) or lithium-ion batteries (light and efficient).

For outdoor road lighting solar street lights, LiFePO4 is the first choice. The battery solution of 12.8V and 25.6V systems commonly used in the market is a pack composed of multiple cylindrical small cells in series and parallel. The actual number of cycles of this battery solution is about 2,000 times. Solway's upgraded square battery solution uses large single-cell lithium iron phosphate power battery-level cells with better performance from China's top three brands. The battery cycle can actually reach up to 5,000 times, which is 2-3 times the number of cycles of cylindrical batteries. It truly ensures quality and realizes a true five-year warranty. It can be said that Solway's battery solution represents the future trend of solar street light battery use.
