The FC4680 large cylindrical cell (BYD)is a new kind of cylindrical lithium-ion battery that is designed to power electric vehicles. It gets its name from its dimensions—46 millimeters in diameter and 80 millimeters in height. This larger size allows it to store more energy and handle more heat, making it ideal for high-performance applications，and adopt multi-tab design and their manufacturing processes are fully-developed,which featured high safety, long cycle life, high power, and low cost, are a great fit for small power products.
