Maintenance Tips
- Use only with 12V LiFePO4, AGM, Lead-Acid + 36V LiFePO4 systems (correct mode selection required)
- Install in a dry, well-ventilated marine compartment to prevent heat buildup
- Ensure proper airflow around all 4 charging banks during operation
- Keep vents clear; charger uses active cooling for thermal control
- Connect with correct polarity and verify battery type mode before charging
- Inspect cables regularly for corrosion, wear, or loose connections
- Avoid water spray or immersion despite IP-rated sealing (IP67/IP68 class design)
- Use a stable AC input (120–240V) for consistent charging performance
- Do not mix incompatible voltages or battery chemistries on any bank
- Mount securely to reduce vibration damage in marine conditions
- Allow charger to cool before storage after long charging cycles
- Check LED indicators regularly for charging status and faults
- Disconnect after full charge to avoid unnecessary standby load
- Avoid undersized extension cords to prevent voltage drop and overheating
- Keep operating temperature within -10°C to 40°C range for best lifespan
