Warnings & Precautions

Charging
  • Use a Dedicated Li-ion Charger: Always use a charger specifically designed for lithium-ion batteries
  • Charge Within Specifications: Do not charge above the maximum voltage of 4.2V or exceed the maximum charge current
  • Temperature Monitoring: Charge only between 0°C to 45°C. Never charge a battery that is below freezing (0°C) or feels hot to the touch.
Discharging
  • Avoid Over-Discharge: Stop using the battery before reaching the cut-off voltage of 2.5V. Over-discharging can cause irreversible internal damage.
  • Respect Current Limits: While rated for 45A continuous, sustained operation at maximum load can generate heat and reduce lifespan.
  • Temperature Management: Avoid discharging outside the recommended temperature range (-20°C to 60°C).
Storage
  • Partial Charge Storage: For long-term storage (longer than one month), store the battery at a 30%-50% State of Charge (SOC).
  • Cool and Dry Environment: Store in a cool, dry place away from direct sunlight and moisture. Ideal storage temperature is between -20°C to 25°C.
