Usage precautions and safety warnings

Charging

• Use LiFePO4-Specific Chargers: Lead-acid or other chemistry chargers can damage the battery. Opt for smart chargers with LiFePO4 profiles (CC/CV method: 3.65V cut-off).

• Temperature Limits: Do not charge below 0°C or above 65°C to prevent capacity degradation.

Discharging

• Avoid Deep Discharge: Do not discharge below 2.5V to prevent irreversible damage.

• Current Limits: Do not exceed 280A continuous discharge unless for short peaks (≤3 sec at 3C).

Safety

• No Modification: Do not disassemble or bypass the built-in protections.

• Emergency Handling: In case of damage, submerge in saltwater (for discharged batteries) and contact professionals.

Storage & Maintenance

• Partial Charge Storage: Store at 30%~50% SOC in a cool, dry place (ideally <35°C).

• Regular Checks: Inspect terminals for corrosion and clean with a dry cloth.

• Recharge Interval: Recharge every 3 months during long-term storage to maintain health.
