‌2. Recommended Charging Method‌:
Use a ‌dedicated 4S Li-ion CC/CV balanced charger‌ set to ‌16.8V ±0.1V‌ (4.2V per cell).

• • ‌Optimal charge current‌: ‌0.5C = 1.5A‌ → maximizes cycle life (>800 cycles)
  • ‌Maximum charge current‌: ‌1C = 3.0A‌ → for fast charging (reduces cycle life to ~500 cycles)
  • ‌Balancing is mandatory‌: Always use a ‌balanced charger‌. Unbalanced charging risks ‌cell overvoltage‌, leading to ‌swelling, thermal runaway, or fire‌.

  ‌Storage Guidelines‌:

  • ‌Short-term storage (<1 month)‌: Maintain at ‌14.8V–15.6V‌ (3.7–3.9V per cell) → ~50–70% SOC
  • ‌Long-term storage (>1 month)‌: Store at ‌15.2V (3.8V per cell)‌ → ~50% SOC, in dry, cool environment (‌15–25°C‌)
  • ‌Recharge interval‌: Recharge every ‌3 months‌ if unused to prevent deep discharge damage

  ‌Operating Environment‌:

  • ‌Charge temperature‌: ‌0°C to 45°C‌
  • ‌Discharge temperature‌: ‌-20°C to 60°C‌
  • ‌Avoid‌: Exposure to water, metal contact, crushing, or direct sunlight

  ‌Safety Warnings‌:

  • ❌ Never disassemble, puncture, or modify the pack
  • ❌ Never charge with non-balanced or NiMH/lead-acid chargers
  • ❌ Never expose to temperatures >65°C or < -30°C
  • ✅ Always use original or certified replacement chargers
  • ✅ Store away from flammable materials and metal objects
