The 542666 3.7V 1050mAh rechargeable lithium polymer battery is a reliable LiPo battery designed for beauty devices. It delivers stable output, high energy density, lightweight structure, and long cycle life for compact electronic applications.
Soft-pack lithium polymer batteries (LiPo), encapsulated in aluminum-plastic composite film, are widely used in modern consumer electronics due to their flexibility, safety, and high energy density.
1. Structural Flexibility: Aluminum-plastic film allows ultra-thin and custom-shaped battery designs.
2. Safety Performance: Soft-pack structure reduces explosion risk and improves safety under abnormal conditions.
3. High Energy Density: Provides long runtime with low self-discharge performance.
1. Design Flexibility: Suitable for compact beauty devices and wearable electronics.
2. Lightweight Structure: Lower weight compared to metal-cased batteries with reliable sealing performance.
3. Long Cycle Life: Supports frequent charge and discharge cycles in daily use.
Note: External protection is recommended due to soft-pack structure.
