The NS-4S13P-26650-40000 is a high-performance 12V 40Ah LiFePO4 battery pack designed specifically for the All-in-One LED solar street lamp industry. Utilizing advanced Lithium Iron Phosphate (LiFePO4) technology, this pack offers a safer, longer-lasting, and more environmentally friendly alternative to traditional lead-acid or standard lithium batteries.

With a massive 512Wh energy capacity, this battery pack ensures that integrated solar street lights remain powered through multiple rainy days, providing reliable, high-intensity illumination for highways, parking lots, and industrial parks.

Technical Advantages & Robust Design

• Superior Life Cycle: The LiFePO4 chemistry provides over 2,000 deep discharge cycles, ensuring a service life of 5–8 years in outdoor solar applications.

• Ultra-Slim Profile: At only 30mm thick, the 270x346x30mm dimensions are optimized for the flat compartments of “All-in-One” integrated solar light housings.

• Advanced BMS Protection: The built-in Battery Management System (BMS) offers comprehensive safety against short circuits, overcharging, over-discharging, and over-current, even in extreme temperature conditions.¹

• Excellent Sealing & Durability: Engineered with high-quality PVC and professional sealing techniques, it is built to resist humidity and vibration, ensuring reliability in remote installations.
