Important Notes

State of Charge (SOC):

  • Optimal: Maintain 40-60% (3.7-3.8V per cell)
  • Prohibited: Long-term storage at <10% or 100% SOC (accelerates aging)

Temperature Control:

  • 15-25°C: Ideal environment (<2% annual degradation)
  • -20~45°C: Permissible range (requires SOC control)
  • 50°C or <-30°C: Strictly prohibited (hazard risk)

Physical Protection:

  • Avoid compression/impact (even with ABS casing)
  • Keep away from metal objects to prevent short circuits

Recommendations:

For long-term storage (>1 month), perform periodic brief charge/discharge cycles to maintain lithium-ion activity and ensure normal energy output. We recommend performing a shallow cycle (30%→80%) every 3 months.
