Usage precations and safety warnings
Charging
- Charge Voltage: Never exceed 3.65V per cell to prevent overcharging, which can lead to thermal runaway .
- Temperature Limits: Do not charge below 0°C or above 45°C to avoid capacity degradation and potential damage .
Discharging
- Avoid Deep Discharge: Do not discharge below 2.5V to prevent irreversible damage. Maintaining a minimum charge of 20% is recommended for longevity .
- Current Limits: Do not exceed 60A continuous discharge unless for short peaks (≤30s) .
- Temperature Management: Avoid discharging at temperatures below -20°C or above 60°C to maintain battery health .
Storage & Maintenance
- Partial Charge Storage: Store at 40%-60% State of Charge (SOC) in a cool, dry place (ideally 20-25°C) to minimize calendar aging .
- Regular Checks: Inspect for swelling, corrosion, or leaks. Clean terminals with a dry cloth if necessary .
- Recharge Interval: Recharge every 3 months during long-term storage to maintain battery health .
