Each module in a stacked battery system typically contains lithium iron phosphate (LiFePO4) cells, known for their safety, long cycle life, and stable performance under various operating conditions. . A stackable battery is an energy storage solution made up of several battery modules arranged in a stack. These modules are linked either in series or parallel to enhance the system's total capacity and voltage. Instead of utilizing a single large battery unit, these systems combine multiple smaller battery modules, stacking them together either physically or electrically to achieve the desired energy capacity and power. . A stacked battery refers to a configuration where multiple individual cells are stacked on top of one another, often in a compact arrangement. Stacked batteries are commonly used in. . megawatts.
