Product Overview

This 12V 80Ah LiFePO4 battery is an integrated energy storage solution designed specifically for solar street lighting systems. It combines lithium iron phosphate cell technology with built-in BMS protection and MPPT functionality, enabling efficient energy storage and stable power output for off-grid lighting applications.

Compared with traditional lead-acid batteries commonly used in earlier solar street light systems, this lithium-based solution offers higher energy efficiency, reduced weight, easier installation, and significantly longer service life. It is engineered for outdoor environments where reliability, low maintenance, and long-term stability are required.


Key Advantages

One of the main benefits of this battery is its compact size and lightweight structure. With significantly lower weight compared to lead-acid and gel battery systems, transportation and handling become easier and more cost-efficient, especially for large-scale lighting projects.

The battery also provides high energy density, allowing more usable power to be stored within a smaller physical footprint. This improves system efficiency and supports longer lighting durations in solar street applications.

Installation is simplified due to its modular design. Unlike traditional systems that require underground battery pits and sealed enclosures, this lithium battery can be directly mounted on lamp poles or integrated into the lighting structure, reducing construction complexity and installation time.

Maintenance is also greatly simplified. Instead of excavating buried battery boxes for replacement or inspection, the unit can be accessed directly at the pole or mounting position, reducing labor costs and service downtime.

Electrical Specifications

The battery operates at a nominal voltage of 12.8V with a rated capacity of 80Ah, providing a total energy storage capacity of 1024Wh. Internal resistance is kept at ≤30mΩ to ensure stable output performance and efficient energy transfer.

Energy conversion efficiency reaches ≥98%, while monthly self-discharge is maintained below 5%, supporting long-term standby applications in outdoor environments. The battery is built using LiFePO4 chemistry, known for its stability and long cycle life.

The enclosure is made from cold-rolled steel, offering strong structural protection, and the system is rated IP65 for resistance against dust and water ingress. Standard dimensions are 360 × 202 × 154mm, with a total weight of approximately 12.6kg.

Discharge Performance

The battery supports a continuous discharge current of 40A, making it suitable for stable LED street light operation. It also supports short-term peak discharge of up to 60A for up to 10 seconds, ensuring reliable performance during load fluctuations.

The recommended discharge cut-off voltage is 10V, while the BMS protection system disconnects at 8.2V and restores operation at 8.6V. In abnormal conditions such as short circuits, protection is triggered within 100–300 microseconds to ensure system safety.

Charging System

Charging is controlled using a CC-CV method to ensure efficient and safe energy storage. The charging voltage range is set between 13.7V and 14.6V, while the recommended floating voltage is 13.5V to 14.3V for long-term stability.

The recommended charging current is 15A, with a maximum allowable charging current of 40A depending on system requirements. The BMS charging cut-off voltage is set at 15V to prevent overcharging and protect cell integrity.

Temperature Performance

The battery is designed for outdoor environments and supports a wide operating temperature range. It can discharge from -20°C to 60°C and charge between 0°C and 55°C. Storage temperature ranges from -20°C to 60°C.

To ensure safety under extreme conditions, the BMS includes high-temperature protection, which activates at 85°C and automatically shuts down the system when necessary.

Application Scenario

This battery is specifically designed for solar street light systems and is widely used in urban lighting projects, rural road lighting, park lighting, campus lighting, industrial area illumination, and remote off-grid lighting systems.

Its integrated design, long cycle life, and stable performance make it an ideal replacement for traditional lead-acid battery systems in modern solar lighting infrastructure.
