AGM and Gel batteries are the most commonly used Lead-Acid batteries for solar street lights. Lithium-Ion (Li-Ion) batteries are among the most popular batteries for solar street lights, but also the most expensive ones. They use a lithium metal oxide cathode and a lithium-carbon anode, immersed in a lithium salt electrolyte.
It is very important for the batteries in the entire solar street light system. During the day, it stores the energy generated by solar panels and then discharges to supply energy to the solar street lamp when the light is insufficient or at night.
Solar-street lights with lithium iron phosphate batteries on the market are generally divided into 3.2V systems, 6.4V systems, and 12.8V systems. For small power and strict price requirements, 3.2V battery packs are generally used. The 12.8V battery packs are mainly used for high-quality street lights, it is long-lasting solar batteries.
Lithium batteries are a more advanced technology delivering around 4,000 cycles while operating at an 80%-100% DoD. Each battery has a different type of safety certification, regarding electrolyte chemicals and the manufacturing process. Solar street lights require a battery with UL-8750 certification or a safer one.
Solar street lights require a battery with UL-8750 certification or a safer one. One major aspect to consider in safety measures is avoiding batteries falling under thermal runaway, this can rapidly heat the battery and cause it to explode or release hazardous gases.
The rated voltage of the single unit is 3.2V, and the charge cut-off voltage is 3.6V~3.65V. Solar-street lights with lithium iron phosphate batteries on the market are generally divided into 3.2V systems, 6.4V systems, and 12.8V systems. For small power and strict price requirements, 3.2V battery packs are generally used.
