Key Advantages

Its slim and compact design is especially suitable for size-sensitive wearable and handheld devices.


Medium capacity and high energy density: A nominal capacity of 2500mAh and an energy density of 9.25Wh provide 6-12 hours of continuous power for small devices (such as smartwatches and Bluetooth speakers).


Wide temperature range adaptability and high discharge rate:


Operating temperature range: Standard models support discharge from -20℃ to 60℃.


Safe and reliable performance:


Multiple protection mechanisms: Built-in overcharge, over-discharge, and short-circuit protection circuits; the soft-pack structure makes it less prone to explosion or leakage under abnormal conditions.


Long cycle life: Over 500 cycles under 0.5C charge/discharge conditions, with a capacity retention rate ≥80%.


Low self-discharge rate: Monthly self-discharge rate ≤3%, minimal power loss during long-term idle periods, suitable for backup power scenarios.


Compatibility and customization capabilities.
