A pouch U-shaped LiPo battery is a custom lithium polymer cell made with a flexible aluminum-laminate pouch and shaped to fit around internal components such as circuit boards, motors, or sensors.

Its U-shaped design helps use space that a standard rectangular battery cannot reach, making it a good choice for compact and irregular product layouts. With a slim, lightweight structure, it is commonly used in wearables, ultra-thin laptops, portable medical devices, and other space-limited electronics.
