2. Physical & Safety Features‌‌

  • Prismatic Pouch Design‌: Built in a slim, rectangular polymer pouch with approximate dimensions of ‌6.5 × 40 × 60 mm‌, optimized for integration into compact, high-performance devices such as ‌portable Bluetooth speakers, mini drones, handheld gaming controllers, and professional-grade voice recorders‌.
  • Lightweight Construction‌: Weighs approximately ‌~68g‌, offering a favorable power-to-weight ratio for portable electronics requiring elevated voltage without bulk.
  • Flame-Retardant Enclosure‌: Utilizes ‌UL-94V0-rated polymer casing‌ to suppress thermal propagation and meet international safety standards for consumer electronics.
  • Integrated Protection Circuit Module (PCM)‌: Equipped with advanced multi-layer safeguards including:
    • Overcharge protection‌ (cut-off at ‌8.45V ±0.05V‌, i.e., 4.225V per cell)
    • Over-discharge protection‌ (triggered below ‌6.0V‌, i.e., 3.0V per cell)
    • Short-circuit detection‌ (<1ms response time)
    • Overcurrent limit‌ (supports up to ‌1C continuous discharge = 1.95A‌)
    • Thermal shutdown‌ at ‌60°C (discharge)‌ and ‌45°C (charge)‌ per cell
  • 2S Series Configuration‌: Two 3.7V, 1950mAh cells connected in series to deliver ‌7.4V nominal voltage‌, enabling direct compatibility with 7.4V-rated systems without external boost converters.
  • DC Terminal Design‌: “DC” indicates a ‌2-pin direct solder pad or JST-XH-style DC connector‌, facilitating secure, low-resistance connections ideal for OEM integration in fixed-mount or semi-permanent applications.

3. Charging & Maintenance Guidelines

  • Recommended Charging Method‌: Use a ‌dedicated 2S Li-Po CC/CV charger‌ set to ‌8.4V ±0.05V‌ (4.2V per cell). Optimal charge current: ‌0.5C (975mA)‌ for maximum cycle life; maximum allowable charge current: ‌1C (1.95A)‌ for fast charging.
  • Balancing Requirement‌: ‌Critical‌ — must be charged using a ‌balanced charger‌ to ensure both cells remain within ±0.05V of each other. Unbalanced charging risks overcharging one cell, leading to swelling or failure.
  • Charging Environment‌: Charge only in ‌dry, ventilated areas‌ within ‌0°C to 45°C‌. Avoid charging on flammable surfaces or in enclosed spaces.
  • Discharge Management‌: Never discharge below ‌6.0V‌ (3.0V per cell). Devices must include ‌low-voltage cutoff‌ to prevent irreversible cell damage.
  • Storage Protocol‌:
    • For short-term (<1 month): Store at ‌40–80% SoC (6.8–7.8V)‌.
    • For long-term (>1 month): Store at ‌~50% SoC (7.4V)‌ in a cool, dry location (‌15–25°C‌).
    • Recharge every ‌3 months‌ if unused to prevent deep discharge and cell degradation.
  • Handling Precautions‌: Avoid exposure to water, metal contact, or mechanical stress. Do not attempt to disassemble, solder directly to cell tabs, or modify the PCM.
