⚠️ Important Notes & Recommendations
- State of Charge (SOC): Maintain 40-60% (3.7-3.8V per cell) for optimal longevity. Avoid long-term storage at <10% or 100% SOC.
- Physical Protection: Metal housing provides durability, but avoid compression/impact. Keep away from metal objects to prevent short circuits.
- LCD Display: Real-time voltage, capacity, and status monitoring via built-in display.
- Long-term Storage (>1 month): Perform periodic shallow charge/discharge cycles (30%→80%) every 3 months to maintain battery health.
- Temperature Control: Store and operate within specified ranges. Extreme temperatures accelerate aging and pose safety risks.
