2. Physical & Safety Features
-
Equipped with an integrated Protection Circuit Module (PCM), the battery provides multi-layered safety safeguards:
- Overcharge protection: Cuts off at 2.75V ±0.05V
- Over-discharge protection: Activates below 2.8V
- Short-circuit protection: Responds within <1ms
- Overcurrent limit: Supports up to 1C continuous discharge (2.2A)
- Thermal shutdown: Triggers at 60°C during discharge and 45°C during charge
For optimal performance and longevity, charging should be performed using a dedicated CC/CV (constant current/constant voltage) lithium-ion charger set to 4.2V ±0.05V. The recommended charge current is 0.5C (1.1A) for extended cycle life, with a maximum allowable charge current of 1C (2.2A) for fast charging scenarios. Unlike multi-cell packs, this single-cell design does not require balancing, but consistent voltage regulation remains critical.
3. Charging & Maintenance Guidelines
- Operating temperature: Charge between 0°C and 45°C, discharge between -20°C and 60°C
- Storage conditions: For short-term (<1 month), store at 3.8–4.0V (40–80% charge); for long-term (>1 month), maintain at 3.7V (~50% charge) in a cool, dry environment (15–25°C)
- Periodic maintenance: Recharge every 3 months if unused to prevent deep discharge damage
- Connection type: Features a 2-pin DC solder pad or JST-PH style connector, enabling secure, low-resistance connections ideal for OEM integration in fixed or embedded systems
Usage precautions:
-
- Avoid exposure to water, metal contact, puncture, or physical deformation
- Never disassemble, directly solder to cell terminals, or modify the PCM
- Use only compatible chargers and avoid charging unattended or on flammable surfaces
