Q: Does it automatically stop charging when the battery is full?
A: Yes, it includes smart charging technology with automatic shutoff and BMS communication for safe, precise charging.
Q: Is it safe for marine environments?
A: Yes, it is built for harsh marine conditions with thermal protection, waterproof design elements, and multiple electrical safeguards.
Q: What protection features are included?
A: It includes over-voltage, over-current, short-circuit, reverse polarity, and temperature protection for reliable and safe operation.
Maintenance Tips
- Use only with 36V LiFePO4 lithium batteries (43.3–44.2V charge profile)
- Plug into a stable 120–240V AC power source to avoid charging instability
- Install in a dry, well-ventilated marine area (heat builds during 10A charging)
- Do not block vents; ensure proper airflow for cooling system
- Keep cables, connectors, and fuse points clean and corrosion-free
- Avoid submersion or direct water spray despite IP68 rating
- Always check LED indicators for charge/fault status before use
- Ensure correct polarity and secure connections before powering on
- Avoid using undersized extension cords (prevents voltage drop/overheating)
- Let charger cool before storing after long charging sessions
- Do not use with lead-acid or mismatched voltage batteries
- Mount securely to reduce marine vibration damage
- Disconnect after full charge to avoid unnecessary standby load
- Keep operating temperature within -20°C to 50°C range
