Lithium Iron Phosphate (LiFePO4) batteries are available in various configurations, often categorized by their nominal voltage and capacity, leading to distinct series. A battery series refers to the arrangement of individual cells connected in sequence to achieve a desired voltage output. For example, connecting four 3.2V LiFePO4 cells in series results in a 12.8V battery pack suitable for replacing lead-acid batteries.
Selecting an appropriate series is crucial for system compatibility and performance optimization. Higher voltage series offer advantages in power delivery and reduced current requirements, leading to smaller wiring and more efficient inverter operation. Historically, the development of different series configurations has been driven by the need to meet the diverse voltage requirements of various applications, ranging from portable electronics to electric vehicles and grid-scale energy storage.
