Key Advantages
- Thin and Lightweight Design: Flexible polymer electrolytes enable compact structures ideal for portable devices where space and weight are critical.
- Flexible Shape and Size: Customizable form factors suitable for diverse applications requiring specific battery dimensions.
- High Energy Density: Stores more energy in smaller volumes, enabling longer operation times between charges compared to traditional battery types.
Main Features
Flat and slim design perfectly suited for compact layouts in outdoor equipment. The soft-pack form factor eliminates the need for a rigid shell, allowing flexible integration into confined spaces of devices.
With 2000mAh capacity and 7.4Wh energy, this battery offers optimal balance between lightweight design and battery life. For low-power devices, a single charge supports 5-10 days of intermittent operation; for medium-power devices, it provides 8-12 hours of continuous use.
The 3.7V nominal voltage directly matches most portable device power supply systems, eliminating the need for additional voltage conversion circuits. This simplifies design, reduces failure rates, and improves actual battery life.
Excellent wide temperature tolerance allows stable discharge from -20℃ to 60℃. Maintains over 70% discharge efficiency in low-temperature environments and resists thermal issues in high-temperature conditions.
Aluminum-plastic film soft-pack encapsulation provides superior safety. Eliminates explosion risks associated with hard-shell batteries, with bulging instead of combustion in case of impact or puncture.
Long cycle life of ≥500 cycles reduces long-term maintenance costs for equipment requiring extended outdoor use, particularly beneficial for remote environment applications.
