2. Physical & Safety Features‌‌

  • Prismatic Pouch Design‌: Constructed in a slim, rectangular polymer pouch with approximate dimensions of ‌4.5 × 56 × 68 mm‌, optimized for integration into space-limited devices such as ‌smart pens, compact voice recorders, Bluetooth headsets, and wearable health trackers‌.
  • Lightweight Construction‌: Weighs approximately ‌~45g‌, enabling ergonomic use in handheld and wearable applications without adding significant bulk.
  • Flame-Retardant Enclosure‌: Uses ‌UL-94V0-rated polymer casing‌ to resist ignition and limit thermal spread under abnormal conditions.
  • Integrated Protection Circuit Module (PCM)‌: Features comprehensive safety controls including:
    • Overcharge protection (cut-off at ‌4.25V ±0.05V‌)
    • Over-discharge protection (triggered below ‌3.0V‌)
    • Short-circuit detection (<1ms response)
    • Overcurrent limit (supports up to ‌1C continuous discharge = 2.0A‌)
    • Thermal shutdown at ‌60°C (discharge)‌ and ‌45°C (charge)
  • Single-Series Configuration (1S)‌: Maintains standard 3.7V nominal voltage for seamless compatibility with most low-to-mid power Li-ion systems.
  • 3M Terminal Design‌: Indicates a ‌3-pin micro-connector interface‌ (typically V+, V−, and NTC thermistor), enabling smart charging, temperature monitoring, and secure plug-and-play integration in OEM devices.

3. Charging & Maintenance Guidelines

  • Recommended Charging Method‌: Use a ‌CC/CV (constant current/constant voltage)‌ charger set to ‌4.2V ±0.05V‌. Optimal charge current: ‌0.5C (1.0A)‌ for maximum cycle life; maximum allowable charge current: ‌1C (2.0A)‌ for faster top-up.
  • Charging Environment‌: Charge only in ‌dry, ventilated areas‌ within ‌0°C to 45°C‌. Avoid charging in direct sunlight, near heat sources, or in humid environments.
  • Discharge Management‌: Never discharge below ‌3.0V‌ to prevent cell degradation and loss of capacity. Devices should include low-voltage cutoff circuitry.
  • Storage Protocol‌:
    • For short-term (<1 month): Store at ‌40–80% SoC‌.
    • For long-term (>1 month): Store at ‌~50% SoC (3.7–3.8V)‌ in a cool, dry location (‌15–25°C‌).
    • Recharge every ‌3 months‌ if unused to maintain cell health and prevent deep discharge.
  • Handling Precautions‌: Avoid exposure to water, metal objects, or mechanical stress. Do not attempt to disassemble, solder directly to cells, or modify terminals.
  • End-of-Life Disposal‌: Recycle through certified lithium-ion battery recycling programs. ‌Never incinerate or discard in regular trash‌ due to fire and environmental hazards.
