What is Soft Pack LiPo Battery?
Soft Pack LiPo Battery (also called pouch cell or polymer lithium battery) uses an aluminum-laminated film outer shell instead of a rigid metal cylinder. Key advantages:
- Ultra-Compact & Lightweight – Perfect for small devices and wearables
- Flexible Form Factor – Adaptable to various slim device designs
- Higher Energy Density – More power in a smaller footprint
- No Pressure Vent Required – Safer under thermal stress
- Flexible Shape – Can be customized to fit unique device contours
