Pouch Curved-shaped Lithium Polymer Battery Manufacturer | Custom Curved Lipo Battery Supplier

Name: China Pouch Curved Lipo Battery Manufacturers, Suppliers and Factory - Customized Service - Blumoti
Brand: Blumoti
SKU: 289577496

A pouch curved LiPo battery is a custom lithium polymer cell made with a flexible aluminum-laminate pouch and shaped with a defined arc to fit curved product designs.

Unlike a standard flat battery, its curved profile can better match the internal structure of devices such as smartwatches, TWS charging cases, wearable health monitors, and other compact electronics. The bend angle, size, capacity, tabs, wires, and protection circuit can be customized based on the device layout.

With its slim and lightweight structure, a curved pouch LiPo battery helps improve space utilization while providing reliable power for products where fit, comfort, and portability matter.

Pouch Curved Lipo Battery Features

Customizable shape and curvature.

The curvature and overall form factor can be tailored to the device's internal space. It offers high dimensional accuracy and excellent batch-to-batch consistency.

Low-rate discharge for extended battery life.

Due to its structural design, the curved battery is well suited for stable, low-rate discharge, helping devices achieve longer standby time.

Low self-discharge.

Monthly self-discharge is less than 2%.

Applications for Pouch Curved Lipo Battery Battery

Arcshaped LiPo batteries are primarily used in wearables and compact, irregularly shaped electronics-especially smart rings, wristbands, watches, earphones, AR/VR devices, medical patches, and curved IoT products. They're best suited for applications where space is extremely tight, the shape is curved, and the battery needs to fit the human body or a contoured enclosure.

01/

Smart rings, wristbands, watches, and fitness trackers

The curved shape follows the contour of the wrist or finger while reducing overall device thickness.

02/

TWS earbuds, ear hook headphones, and hearing aids

Designed to fit the irregular curves inside earpieces, making use of awkward corner spaces.

03/

AR/VR headsets and smart glasses

Positioned along curved parts like the temples or head straps to improve weight balance and wearing comfort.

04/

Smart clothing, medical patches, and health monitoring devices

Thin, flexible, and conformal to body contours-ideal for heart rate patches, monitoring rings, heated garments, and other onbody devices.

05/

Smart helmets, sports protective gear, and IoT sensors

Placed along curved housings to reduce bulges and simplify structural integration.

06/

Curvedscreen devices, automotive interiors, and irregular consumer electronics

Saves space inside curved or customshaped enclosures, improving design freedom and aesthetics.

FAQ

1. What's the MOQ?

For custom curved batteries, our MOQ is 3,000 units.

2. Can the curvature of the pouch curved LiPo battery be customized?

Yes. The bend angle, cell size, capacity, tab direction, wire length, connector, and protection circuit can be customized based on your product structure. If you have a 3D drawing, battery compartment size, or sample device, our team can help evaluate the best battery design.

3. What information should I provide for a quotation?

To get an accurate quote, please share the required voltage, capacity, battery size limit, bend angle or curved space dimensions, discharge current, connector type, wire length, charging method, and application. A product drawing or battery compartment photo will help speed up the design process.

4. Can I order samples before mass production?

Yes. Sample orders are available for design testing, assembly checking, and performance validation. For custom curved LiPo batteries, we recommend testing samples in the actual device before confirming the final structure and mass production details.

5. What certifications can you support?

Blumoti can support common battery compliance documents based on the target market and shipping method, such as UN38.3, MSDS, CE, CB, IEC 62133, KC, BIS, and other required documents. Certification requirements may vary depending on the battery model, destination country, and final application.
