When choosing a solar street light system, selecting the right battery is critical to ensuring long-term performance, reliability, and cost-efficiency. Are you searching for a battery powered street light solution that can withstand extreme weather, deliver long backup hours, and require minimal maintenance?
If so, investing in a high-quality lithium-ion battery is the smartest choice. Among all battery technologies available today, LiFePO4 (Lithium Iron Phosphate) stands out as the safest, longest-lasting, and most cost-effective option for solar street lighting applications. Compared to traditional NCM, lead-acid, or gel batteries, LiFePO4 offers superior thermal stability, longer cycle life, and better resilience against deep discharges and temperature fluctuations.
At TENMAX, we specialize in providing advanced solar street light battery solutions using high-quality cylindrical LiFePO4 cells, including 32140, 32700, 18650, and 21700 models. Designed for durability and efficiency, our products ensure reliable energy storage for street lighting systems across various environmental conditions.
Why Choose Our LiFePO4 Batteries for Your Solar Street Light
We specialize in LiFePO4 battery solutions that deliver superior performance, safety, and durability. Here’s why our batteries are the smart choice for powering your solar street light systems.
-
High Energy Density
Our batteries deliver outstanding energy storage capacity within a compact footprint, making them ideal for modern solar street light with inbuilt lithium ion battery designs. This ensures longer illumination hours even with limited space available for battery housing. -
Long Cycle Life
Thanks to the stable chemistry of LiFePO4, our batteries offer more than 3,000–5,000 charge-discharge cycles at 80% Depth of Discharge (DOD). Compared to lead-acid or NCM batteries, this translates into significantly longer operational life and a much lower total cost of ownership. -
Wide Temperature Tolerance
Whether installed in freezing winters or scorching summers, our batteries maintain excellent performance across a wide operating temperature range (-20°C to 60°C). This makes them the perfect solution for battery powered street light projects deployed in diverse climates. -
Safety and Reliability (Built-in BMS Protection)
Every TENMAX battery pack is equipped with a sophisticated Battery Management System (BMS) that protects against overcharging, over-discharging, overheating, and short circuits. Safety is paramount, ensuring reliable operation for your rechargeable street light systems even in critical outdoor environments. -
Maintenance-Free Operation
Unlike traditional lead-acid batteries that require regular water topping and inspections, our lithium batteries are fully sealed and maintenance-free. This greatly reduces ongoing labor costs and eliminates the risk of system downtime. -
Environmental Friendliness
LiFePO4 batteries are non-toxic, non-contaminating, and highly recyclable. By choosing a solar street light inbuilt battery based on lithium iron phosphate technology, you are making a sustainable choice that reduces environmental impact.

FAQs
How long does a solar street light battery last?
A high-quality solar street light battery typically lasts between 5 to 10 years, depending on the battery chemistry and operating conditions. LiFePO4 batteries from TENMAX offer superior cycle life — often exceeding 3,000–5,000 cycles — making them the most durable and cost-effective choice compared to traditional lead-acid or NCM options.
How do I maintain a solar street light battery?
One of the advantages of using a rechargeable street light system with LiFePO4 batteries is that it requires minimal maintenance. TENMAX batteries are fully sealed, maintenance-free, and equipped with a smart BMS that continuously monitors and protects the battery, ensuring optimal operation without the need for manual intervention.
What is the ideal battery temperature range?
The ideal operating temperature range for a lithium battery for solar street light applications is typically between -20°C and 60°C. TENMAX batteries are specially engineered to deliver stable performance across wide temperature fluctuations, ensuring year-round reliability even in harsh outdoor environments.
Can I replace only the battery in an old solar street light?
Yes, you can replace just the battery if the rest of your system is still functional. Upgrading to a solar street light battery pack using LiFePO4 cells can significantly improve performance and lifespan compared to older lead-acid systems. TENMAX offers both standard and customized battery packs for easy retrofitting.
What’s the difference among LiFePO4, NCM, and Lead-Acid batteries for solar street lights?
| Feature | LiFePO4 | NCM | Lead-Acid |
|---|---|---|---|
| Cycle Life | 3,000–5,000 cycles | 1,000–2,000 cycles | 300–500 cycles |
| Safety | Very High | Moderate | Low |
| Maintenance | Maintenance-Free | Maintenance-Free | Requires Maintenance |
| Temperature Tolerance | Excellent (-20°C to 60°C) | Good (-10°C to 55°C) | Poor (0°C to 40°C) |
| Cost | Higher upfront, lower lifetime | Moderate | Low upfront, high replacement |
Choosing a solar street light inbuilt battery with LiFePO4 chemistry ensures better safety, longevity, and overall lower costs over the lifetime of your project.
How to calculate the right battery capacity for your solar street light?
To size your battery powered street light correctly, use this formula:
Required Battery Capacity (Wh) = [Load Power (W) × Hours of Operation] × Backup Days / System Efficiency
Then divide by the battery voltage to get the ampere-hour (Ah) rating. TENMAX can assist you in accurately sizing and selecting the ideal solar street light battery for your project needs.
What should be considered when designing a custom pack for a solar street lamp?
When designing a custom solar street light battery pack, it’s important to consider factors such as energy demand, backup time, environmental temperature, enclosure size, and BMS functionality. TENMAX offers tailor-made solutions combining top-grade cells and intelligent management systems to optimize the performance and safety of your solar street light with inbuilt lithium ion battery.
