5. Operating Instructions
5.1 Charging Modes
The charger offers various modes to suit different battery types and conditions. These can be selected via the 'MODE' button on the charger or through the VictronConnect app.

Figure 3: Blue Smart IP65 Charging Modes and Features.
- Li-ion: Charges all 12.8V LiFePO4 Batteries. Can recharge from 0V in case of BMS low voltage protection.
- Recondition: Helps bring under-charged or sulfated lead-acid batteries back to optimal state.
- High [14.7V]: Recommended for specific flooded lead batteries. Use with care.
- Normal [14.4V]: Recommended for flooded, GEL, and AGM starter and deep cycle batteries.
5.2 Charging Stages
The charger employs a smart 7-step charging algorithm:
- Bulk: Charges with maximum current until absorption voltage is reached.
- Absorption: Battery charging with a set voltage/timer, depending on charge mode.
- Float: Charges with lowered voltage, keeping batteries full while passing through power to loads.
- Storage: Keeps charged batteries healthy by reducing the charge voltage to limit tail current, corrosion, and gassing.
5.3 Power Supply Mode
The charger can function as a power supply, providing a stable DC voltage to power loads directly without a battery. This mode can be activated via the VictronConnect app.
5.4 Using the VictronConnect App
The VictronConnect app provides comprehensive control and monitoring capabilities:
- Status: View real-time voltage, current, and charging stage.
- Graph: Visualize charging data over time.
- History: Access detailed records of past charging cycles, including duration, charged Ah, and any interruptions.
- Settings: Customize battery presets, charge current, absorption voltage, float voltage, storage voltage, recondition voltage, temperature compensation, and low temperature cut-off.
- Night Mode: Reduce output current and keep the fan off for silent operation during preset hours.
Important Note: When charging multiple batteries simultaneously, ensure they are of the same chemistry type. The charger is designed to optimize charging for a single battery chemistry at a time.
6. Maintenance
- Regularly inspect the charger, cables, and battery connections for any signs of damage, wear, or corrosion.
- Keep the charger clean and free from dust and debris. Use a dry cloth for cleaning.
- Ensure the charger is operated in a well-ventilated area to prevent overheating.
- For lead-acid batteries, periodically check electrolyte levels (if applicable) and top up with distilled water as needed.
7. Troubleshooting
- Charger not turning on: Check the AC power connection and ensure the outlet is functional. Verify battery connections are secure.
- Battery not charging: Confirm the correct charging mode is selected for your battery type. Check battery voltage; if extremely low, the charger may need to be in a specific recovery mode (e.g., Li-ion 0V recovery or Recondition for lead-acid).
- Overheating: Ensure the charger is in a well-ventilated area and not covered. Reduce the charge current via the VictronConnect app if necessary.
- Bluetooth connectivity issues: Ensure your mobile device is within range. Restart the VictronConnect app or your mobile device. Check if the charger's Bluetooth is enabled.
- Sulfur smell/battery boiling over: Immediately disconnect the charger and consult a battery specialist. This indicates a severe battery issue or incorrect charging parameters.
