Custom Flexible Bendable Li-polymer Battery 150630 130630 160630, 3.7V 22mAh 20mAh 19mAh 18mAh, and More

As electronic devices become smaller, lighter, and more wearable, traditional rigid batteries can no longer meet every design requirement. Many modern products need a power source that can fit into curved, narrow, or irregular spaces without affecting comfort, appearance, or performance. This is where a custom flexible bendable Li-polymer battery becomes an ideal solution.

The Custom Flexible Bendable Li-polymer Battery 150630, 130630, 160630, 3.7V 22mAh, 20mAh, 19mAh, 18mAh, and more is designed for compact electronic devices that require thin structure, stable voltage, and flexible installation. With a nominal voltage of 3.7V and multiple capacity options, this type of battery is suitable for smart wearables, medical patches, smart cards, mini sensors, beauty devices, Bluetooth accessories, and other lightweight electronic products.

What Is a Flexible Bendable Li-polymer Battery?

A flexible bendable lithium polymer battery is a rechargeable battery designed with a soft and thin structure. Compared with standard prismatic lithium polymer batteries, flexible batteries can better adapt to curved surfaces or limited internal spaces. They are often used in products where comfort, lightweight design, and compact integration are important.

Models such as 150630, 130630, and 160630 usually represent different battery dimensions. These small-size batteries can provide capacities such as 22mAh, 20mAh, 19mAh, and 18mAh, depending on the exact structure, thickness, and customer requirements. Although the capacity is small, the battery can still deliver stable power for low-consumption electronic devices.

Why Choose a 3.7V Flexible Li-polymer Battery?

A 3.7V Li-polymer battery is widely used in portable electronics because it offers a good balance between energy density, size, and rechargeability. For compact devices, every millimeter of space matters. A flexible battery allows engineers to place the battery in areas where a rigid battery may not fit.

This is especially useful for devices worn on the body or attached to curved surfaces. For example, smart rings, wearable patches, medical monitoring products, and ultra-thin Bluetooth devices may all require customized battery shapes. A flexible bendable Li-polymer battery helps improve product design freedom while maintaining reliable power output.

Key Features of Custom Flexible Bendable Batteries

One major advantage of flexible Li-polymer batteries is their slim and lightweight construction. These batteries can be customized in size, capacity, connector type, wire length, protection circuit, and discharge performance. For products such as smart labels or wearable sensors, this flexibility makes product development much easier.

Another important feature is stable 3.7V output. Even in small capacities such as 18mAh, 19mAh, 20mAh, or 22mAh, the battery can support low-power electronics with consistent performance. A built-in protection circuit can also be added to protect against overcharge, over-discharge, short circuit, and overcurrent issues.

Custom flexible batteries can also be designed for different bending requirements. However, the bending angle, bending frequency, and installation method should be confirmed during the design stage. Proper structure design helps extend battery life and improve safety during use.

Common Applications

Flexible bendable Li-polymer batteries are widely used in smart wearable products. Devices such as smart bracelets, smart rings, health monitoring patches, electronic skin sensors, and wearable temperature monitors often need small, lightweight, and comfortable battery solutions.

Medical and healthcare devices are also an important application area. Disposable medical sensors, wireless monitoring patches, smart drug delivery accessories, and portable diagnostic devices may require thin batteries that can fit closely to the body. A flexible battery can support a better wearing experience for patients and users.

In consumer electronics, these batteries can be used in Bluetooth tags, smart cards, electronic labels, mini LED products, smart toys, beauty devices, and compact wireless accessories. Their small size makes them suitable for products with limited internal space.

Customization Options for OEM/ODM Projects

For manufacturers developing new electronic products, battery customization is often necessary. Standard batteries may not match the required size, capacity, wire position, or connector. Custom flexible bendable Li-polymer batteries can be designed according to the product’s internal space and working conditions.

Common customization options include battery model, length, width, thickness, capacity, voltage, discharge current, PCM protection board, connector type, wire length, label design, and packaging method. For special applications, engineers can also evaluate temperature requirements, cycle life, charging method, and bending performance.

Before confirming a battery solution, customers usually need to provide product drawings, available battery space, working current, peak current, charging requirements, expected runtime, and application environment. This information helps battery engineers recommend the most suitable structure.

Safety and Quality Considerations

Safety is very important for lithium polymer batteries, especially when the battery is used in wearable or medical-related devices. A reliable flexible battery should use quality cells, stable materials, and proper protection design. Overcharge, over-discharge, short circuit, and excessive bending should be avoided.

During product development, sample testing is recommended before mass production. Customers can test battery fit, charging performance, discharge time, bending suitability, and device compatibility. After the battery design is confirmed, mass production can follow the approved sample standard.

For export markets, customers may also need certifications or test reports depending on the product category and destination country. Common requirements may include UN38.3, MSDS, RoHS, CE-related documentation, or other battery transport and safety documents.
