BAKTH-703450P-1S2P-2M, 3.7V, 2900mAh. 10.73Wh

‌2. Physical & Safety Features‌‌

• ‌Compact Form Factor‌: Dimensions approximately ‌7.0 × 34 × 50 mm‌, enabling integration into slim devices such as smart POS terminals, handheld medical tools, and portable audio systems.
• ‌Lightweight Design‌: Weighs only ~38g, ideal for wearable or handheld applications where ergonomics matter.
• ‌Robust Construction‌: Uses a durable polymer casing with ‌UL-94V0 flame-retardant material‌ for enhanced thermal and mechanical protection.
• ‌Integrated Protection Circuitry‌: Includes safeguards against:
  • Overcharge (max voltage: 4.25V per cell)
  • Over-discharge (cut-off at ~3.0V)
  • Short circuit
  • Excessive current draw (supports up to 1C continuous discharge)
  • Temperature extremes (safe operation: 0–45°C charging, -20–60°C discharging)
• ‌Parallel Configuration (1S2P)‌: Two 1450mAh Li-Po cells in parallel increase capacity without raising voltage, maintaining compatibility with 3.7V systems while improving energy resilience.

3. Charging & Maintenance Guidelines‌

• ‌Recommended Charger‌: Use a ‌constant current/constant voltage (CC/CV) charger‌ set to ‌4.2V ±0.05V‌ with a maximum charge current of ‌0.5C (1.45A)‌ for optimal cycle life and safety.
• ‌Fast Charging Caution‌: While the cell can accept up to 1C charging, prolonged high-current charging may accelerate degradation; ‌0.5C is advised for daily use‌.
• ‌Charging Environment‌: Charge only in dry, well-ventilated areas between ‌0°C and 45°C‌. Avoid charging in high-humidity or enclosed spaces.
• ‌Storage Recommendations‌:
  • For short-term: Keep charged between ‌40–80%‌.
  • For long-term (>1 month): Store at ‌~50% charge‌ in a cool, dry place (ideally 15–25°C).
  • Recharge every 3 months if unused to prevent deep discharge.
• ‌Avoid Physical Stress‌: Do not puncture, crush, or disassemble. Exposure to sharp objects or high impact may trigger thermal runaway.
• ‌Disposal‌: Recycle at certified e-waste facilities. Do not incinerate or dispose of in household trash.
