Advantages of Our Solar Street Light Battery
Our lithium iron phosphate batteries have a cycle life of up to 6,000 times or more, and a service life of 8 to 10 years, minimizing the frequency of replacement and bringing long-term stability to your project.
The energy density of our lithium batteries (especially lithium iron phosphate batteries) for solar street lights can reach 140Wh/kg. Under the same energy output conditions, compared with traditional lead-acid batteries, their volume is reduced by more than 50% and their weight is reduced by more than 60%, which not only saves your transportation costs but also saves a lot of space for your project and maintains its beauty.
Our batteries are compatible with the solar controller for charging and discharging. Our lithium iron phosphate batteries for solar street lights support 0.2 C-0.5 C charging, and it only takes about 4 hours to charge to 80%, shortening the recovery time after rainy days and ensuring the stability of your project. Even on rainy days, the drained battery can resume charging quickly due to the compatible voltage of the solar charger.
Our lithium battery capacity can meet the needs of various backup days. For continuous rainy areas, we can provide up to 300Ah large capacity lithium batteries (or even larger capacity and output power) to achieve at least three days of backup. In addition, our lithium iron phosphate batteries can be used normally in the temperature range of -40℃-70℃ without loss of control and capacity attenuation, reducing the impact of weather factors on your project.
Choose our lithium battery as your solar street light battery or replacement. Its discharge depth can reach 80% without damage. There will be no sudden drop in battery capacity during long-term use. It is very suitable for solar street lights, which require frequent charging and discharging and a long-term energy supply.
We provide IP65 or higher waterproof and dustproof casings for your solar street light batteries to prevent oxidation caused by rainwater leakage. For cold regions, we can also design antifreeze casings for your solar street light batteries to ensure their normal use.
Longer service life reduces the maintenance frequency of your solar street light batteries. You only need to clean the solar panels regularly and check the physical appearance of the batteries, which greatly saves the long-term cost of your project.
We can recommend suitable product specifications for you based on your specific usage requirements, such as bulb power, solar panel power, lighting time, and backup days. According to the specific design of your street lamp, we can customize lithium batteries in special shapes such as square, round, arc, etc.
IP65 Waterproof Solar Light Batteries with Smart Control System
Encased with IP65 waterproof ABS case,our lithium batteries can also be integrated with an all-in one control system for solar street lights,which facilitates the whole system control for lighting time and endurace time.
What Kind of Battery Can You Use for Your Solar Street Light?
For different applications of solar street lights, we provide the following three types of batteries. Please contact us if you want to know more about our battery.
Compared with lead-acid batteries, Lithium ion batteries have significantly longer service life, are also lighter, smaller, and have greater energy density, making them an excellent alternative to lead-acid batteries. However, under high temperature conditions, the service life of Lithium ion batteries will be significantly reduced, and overcharging may cause safety hazards such as fire.
Lithium iron phosphate batteries have a cycle life of more than 6,000 times. Compared with LiMn2O4 batteries, lithium iron phosphate batteries have better thermal stability, making them safer when working at high temperatures. The price of lithium iron phosphate batteries is higher than that of LiMn2O4 batteries, which is suitable for high-performance and long-term solar street light projects.
The advantage of nickel-cadmium batteries is that they have better environmental tolerance and do not require frequent maintenance. At the same time, they are cheaper than lithium batteries, have a discharge depth of up to 60%, and have a longer service life.

When you notice that the street lights have become significantly dimmer than usual, you should consider replacing the battery of your solar street light because it indicates that there may be something wrong with the solar street light battery’s capacity, ability to be charged, and ability to discharge. Then, you are expected to inspect the appearance of the solar street light battery to check for damage, leaks, or corrosion. Then check if the voltage is lower than the normal.For battery failure,pls contact us to identify the reason.
If necessary, you’d better replace the solar street light battery at once, because continuing to use a damaged solar street light battery will do harm to the whole solar street light system.
If you keep your solar street light healthy, you should do regular inspections. Where to inspect? First, check connections. The connections are the parts that are most likely to corrode. In addition, external factors such as strong winds may cause the battery to shift, resulting in poor contact and causing problems with the battery.
Secondly, arrange a smart charging controller for your solar street light system. It can prevent your solar street light battery from overcharging and overdischarging, ensuring a safe charge for your battery.
Thirdly, the solar street light battery is part of the solar street light system. The solar panel should be ≥ 4 times the load power of the lamp. Solar panels need to be cleaned monthly; otherwise, they will harm the solar street light battery.
You need to know the power of the lamps used in your project and the brightness level you want. Generally speaking, for lamps of the same material, the higher the power, the higher the brightness level and the greater the power consumption. To maintain sufficient lighting time, the capacity of your battery must be increased accordingly.
In addition, the longer the lighting time is set and the more backup days there are, the larger the battery capacity is required.
Take a 12.8V lithium battery as an example. If your lamp has a power of 40W and works for 8 hours a day, and needs to store enough electricity for 4 consecutive rainy days, then your battery needs at least a 100Ah capacity. The result is calculated according to the following formula:
Capacity(Ah)=Lamp power(W)×Lighting hours(H)×Backup days÷Rated voltage(V)
Then the calculation result of the above example is: 40(W)×8(H)×4÷12.8(V)=100(Ah)
According to different power requirements, solar street light batteries can be mainly divided into 3V, 6V, 12V, 24V, 36V etc. The power is generally from low to high. For batteries used in public road solar street lights, the battery specifications will not be less than 12.8V 30Ah 384 watt-hours to ensure basic lighting time. If the backup days are taken into account, the battery capacity needs to be further expanded.
3V and 6V systems are mainly used for household lighting or backup power supply with low power requirements. These applications do not have high requirements for lighting time.
It depends on the size, type, capacity, and other customized specifications you require. The price of solar street light batteries with 12.8V rated voltage increases with capacity. The price of a 12.8V 54Ah lead-acid solar street light battery is around 100$, while the price of a lithium iron phosphate solar street light battery with the same specifications is between 150 and 300 US dollars.
