Important Usage Notes
- State of Charge (SOC): Maintain 40-60% (3.7-3.8V per cell) for optimal performance. Avoid long-term storage at less than 10% or 100% SOC as it accelerates aging.
- Temperature Control: Ideal environment is 15-25°C (less than 2% annual degradation). Strictly prohibited to operate at 50°C or below -30°C due to hazard risk.
- Physical Protection: Avoid compression and impact even with protective casing. Keep away from metal objects to prevent short circuits.
- Long-term Storage: For storage longer than 1 month, perform periodic brief charge/discharge cycles (30% to 80% every 3 months) to maintain lithium-ion activity and ensure normal energy output.
