Strong Capacity and Voltage Adaptability:The 3500mAh capacity meets the battery life requirements of small devices (such as smart wearables and small speakers). 3.7V is the universal voltage for polymer lithium batteries, eliminating the need for additional power modules and ensuring wide compatibility.
Flexible Form Factor and Installation:The 1050x60mm thin and flat design, with a soft-pack enclosure without a rigid shell, allows for a close fit to the internal space of devices and adapts to irregular structural designs.
Outstanding Safety and Stability:The soft-pack enclosure reduces the risk of overcharging and overheating, minimizing the risk of explosion and leakage. It typically boasts a charge-discharge cycle life of over 500 cycles, a low self-discharge rate, and minimal power loss when idle.
Main Application:
Smart Wearable Devices: Such as mid-to-high-end smart bracelets and smartwatches. The thin, flat design fits the device design perfectly, and the 3500mAh capacity meets the need for long battery life.
Small digital audio-visual devices: Bluetooth speakers, portable MP3/MP4 players, small voice recorders; 3.7V universal voltage, no additional adapter required; battery life supports several hours of use.
Portable medical devices: Blood glucose meters, small pulse oximeters, portable blood pressure monitors; high safety and low self-discharge rate, suitable for the stability requirements of medical devices.
Mobile terminal accessories: Small power banks (built-in battery), wireless chargers, phone battery cases; soft-pack design for flexible fit within accessory internal spaces.
Small smart home devices: Smart door locks (built-in backup power), wireless sensors, small surveillance cameras; stable battery life and flexible installation.
