    Settings for Victron Blue Smart chargers:

    Victron’s Li-Ion profile is NOT sufficient for non-Victron LiFePO4 batteries. Enter configuration and turn on “ADVANCED” switch, then select “Custom” charge preset. Then click “Advanced Battery Settings”.

    The battery preset should be set to “User Defined”. Turn on the “Expert Mode” switch.

    • Absorption Voltage: 14.6v
    • Float Voltage: 13.8v
    • Storage Voltage: 13.6v
    • Recondition Voltage: Disabled
    • BatterySafe: Disabled
    • Voltage Compensation:
    • Temperature Compensation: Disabled

    Bulk:

    • Bulk Time Limit: 24 Hours
    • Re-bulk Current: Enabled, set to full output current of charger, typically 25A

    Absorption:
