What are the operational best practices for maximizing the lifespan of 280Ah LiFePO4 battery systems?

To maximize the lifespan of 280Ah LiFePO4 battery systems, adhere to the following best practices:Thermal Management: Maintain operational cell temperatures within 15–35°C. Charging below freezing risks lithium plating, while sustained operation above 45°C accelerates calendar aging. Use preheating, thermal pads, or HVAC systems as needed.State of Charge (SOC) Windows: Design controls for 10–90% SOC to...
