Description

Key Features
High Energy Density & Compact Form Factor:
The cell's pouch design allows for a remarkably slim profile of just 4.0mm, enabling integration into ultra-thin and lightweight devices where traditional cylindrical cells cannot fit. Its high 8000mAh capacity packed into a minimal volume provides extended runtime without compromising on size.
Flexible and Lightweight Design:
Unlike rigid metal-cased cells, this pouch cell offers a degree of flexibility in its packaging. This reduces stress on the battery tabs during assembly and makes it suitable for applications that may require slight bending or conforming to non-uniform spaces, all while significantly reducing the overall weight of the end product.
Stable and Consistent Discharge Performance:
Engineered with high-quality internal materials, this cell delivers a flat discharge curve, ensuring stable voltage output for the majority of its discharge cycle. This is crucial for powering sensitive electronics and motors that require consistent voltage to maintain optimal performance.
Long Service Life and Enhanced Safety:
Built with robust lithium-ion technology, the cell is designed to withstand hundreds of charge-discharge cycles with minimal capacity degradation. It incorporates standard safety features, including protection against overcharge and short-circuit, ensuring reliable and safe operation throughout its lifespan.

Application
Portable Consumer Electronics:
Perfect for high-end portable audio equipment, powerful handheld gaming devices, and advanced remote controls, where its high capacity translates to longer usage times between charges.
High-Capacity Power Banks and UPS Backup Systems:
Serves as an ideal core component for compact yet high-capacity power banks, allowing for multiple full charges of smartphones and tablets. It's also suitable for small Uninterruptible Power Supply (UPS) systems that protect networking equipment and smart home hubs from power outages.
Drones, UAVs, and RC Hobbyist Models:
Its excellent energy-to-weight ratio provides longer flight times for drones and aerial photography UAVs. The stable discharge performance is also beneficial for high-speed RC cars and boats, delivering sustained power to the motor.
Light Electric Mobility and Outdoor Gear:
Can be used in battery packs for electric skateboards, compact e-bikes, and motorized camping equipment. It is also well-suited for powering portable medical devices, diagnostic equipment, and a variety of robust industrial sensors and data loggers in the field.
