5kwh Lifepo4 Battery

We have established a comprehensive safety control system from cell entry to finished product delivery. First, all cells use Grade A lithium iron phosphate materials and undergo 100% capacity, internal resistance, and voltage testing and safety sampling before entering the factory. Second, the battery protection board is equipped with our self-developed intelligent BMS system, which has six protection functions: overcharge, over-discharge, overcurrent, short circuit, over-temperature, and undervoltage. Finally, every finished battery undergoes aging testing, insulation withstand voltage testing, and simulated extreme working condition testing before leaving the production line to ensure that every product delivered to customers meets safety standards.

We support multi-dimensional customization services, including appearance dimensions, communication protocols (RS485/CAN), voltage levels, capacity specifications, etc., to adapt to inverters and residential energy storage systems from different brands. At the same time, our engineering team can connect with customers in advance to provide technical support, ensuring perfect compatibility between the product and the customer's system. For bulk orders, we can also provide OEM/ODM customization services according to customer needs, including silkscreen printing, packaging, and instruction manual customization.

We promise that the actual capacity deviation of all products is strictly controlled within ±3%. During factory production, we use high-precision capacity sorting cabinets to sort and match the cells, ensuring the consistency of cells within the same group. After the battery pack is completed, a second capacity test is conducted. Any products that do not meet the capacity standards will be directly reworked and will not enter the market. We can also provide complete factory test reports according to customer needs, making the capacity data transparent and traceable.

We provide standard warranty service for wall-mounted lithium iron phosphate batteries. Under normal use, the product warranty period is 5 years (can be adjusted according to actual conditions). The factory has established a comprehensive after-sales response mechanism. Our technical team will respond to customer feedback within 24 hours. For quality issues not caused by human error, we provide free repair or replacement services. Furthermore, our entire production process is traceable, enabling us to quickly locate the root cause of problems and provide customers with efficient after-sales solutions.

Our wall-mounted lithium iron phosphate batteries utilize highly stable cells and an optimized BMS balancing strategy. Under standard testing conditions, the cycle life can reach over 6000 cycles, with capacity retention still exceeding 80% of the initial capacity. Multiple batches of accelerated cycle life tests have been completed in the factory, and relevant test reports can be provided to customers. Furthermore, our cells have passed international certifications such as UN38.3 and IEC62133, ensuring stable performance and reliable safety during long-term use.
