Shenzhen Blumoti Energy Co., Ltd. is a leading Chinese manufacturer and supplier of pouch ultra narrow lipo battery. If you are looking to source durable, bulk pouch ultra narrow lipo battery from China, feel free to contact our factory for details. Custom orders are welcome.
Pouch Ultra-Narrow LiPo Battery is a subcategory of lithium polymer batteries featuring an ultra-narrow form factor and pouch structure.
With a typical width of 2–8 mm-customizable to even narrower dimensions-and a thickness of 1–5 mm, its slim, strip-shaped design fits extremely tight spaces such as smartwatch crowns and TWS earbud contact modules.
The aluminum-plastic film pouch packaging makes it 20%–30% lighter than comparable rigid batteries. It also supports slight bending and irregular shape customization to better match the internal structure of compact devices.
Pouch ultra-narrow LiPo batteries are ideal for wearables, including earbud stems and slim smart bands, as well as micro IoT sensors, minimally invasive medical devices, and mini GPS trackers. They are an excellent power solution for electronics with extremely limited internal space.
