Maintenance Tips
  • Use only with 12V LiFePO4, AGM, or Lead-Acid + 36V LiFePO4 systems
  • Install in a dry, well-ventilated marine location to prevent heat buildup
  • Ensure proper airflow around all 3 charging banks during operation
  • Connect securely and check polarity before every use
  • Keep terminals and leads clean, tight, and corrosion-free
  • Do not block vents; charger uses active cooling for temperature control
  • Avoid water spray or immersion despite IP-rated protection
  • Use a stable AC input (120–240V) for consistent charging performance
  • Do not use with non-compatible battery voltages or chemistries
  • Inspect cables regularly for wear, cracking, or overheating signs
  • Mount firmly to reduce vibration damage in marine environments
  • Allow charger to cool before storage after long charging cycles
  • Check LED indicators for charge status and fault alerts
  • Disconnect after full charge to avoid unnecessary standby load
  • Avoid undersized extension cords to prevent voltage drop and overheating
