5.1.1. Instant Readout

VictronConnect can display key battery data directly on the Device List page—without needing to connect to the product. This includes visual notifications for warnings, alarms, and errors, allowing quick diagnostics at a glance.

Instant Readout is disabled by default and must be enabled if you wish to display this data. When VictronConnect is first installed, you will be prompted to enable the feature.

Available parameters:

  • Battery voltage

  • Battery current

  • State of charge

  • Remaining time

  • Battery temperature

  • Consumed Ah

  • Visual notifications for warnings, alarms and errors

For details on enabling Instant Readout, refer to the VictronConnect manual, available on the VictronConnect download page.

5.2. Charging

The Lithium SuperPack NG battery can be charged with any battery charger, provided it has a Lithium Iron Phosphate (LFP) charging profile, or a user-defined preset.

Using the correct charging parameters ensures optimal performance, safety, and service life. Refer to the Battery Specification for the detailed charging settings.

Charging characteristics

  • The Bulk/Absorption voltage defines the level at which the battery is charged to full capacity. Once this voltage is reached, the current will gradually decrease until the battery is fully charged and the cells are balanced.

  • The Float voltage maintains the battery at full charge without overcharging it. This stage can be held indefinitely when the system is on standby or under light load.

  • Charging stops automatically when the internal Battery Management System (BMS) detects that all cells are balanced and fully charged.

Charging conditions

  • Charging is only permitted when the battery temperature is between 0 °C and 60 °C. Below or above this range, the BMS will block charging to protect the cells.

  • When the temperature is too low for charging, the internal heater activates when a charger is connected (default setting). Charging will resume as soon as the cell temperature is above 0 °C.

  • The battery may be charged from any DC source, including alternators, DC-DC chargers, solar charge controllers, or mains-powered chargers, as long as the voltage and current limits are within specification.

  • When the battery is switched off via the VictronConnect app or the on/off push button, charging and discharging are disabled. Switching the battery off via the app keeps the Bluetooth connection active and is therefore not suitable for long-term storage.

  • Recondition or equalisation modes must not be used, as they apply voltages too high for LFP chemistry.

Solar charging

When charging from a solar system, use an MPPT solar charge controller with the appropriate LFP profile (for example, Victron SmartSolar or BlueSolar).

Ensure that the charge controller’s voltage limits match the recommended values shown in the table above.

Alternator charging

When charging from an engine alternator, the alternator must be protected from overload.

Use a DC-DC charger between the alternator and the battery to limit current and voltage.

Victron DC-DC chargers (such as the Orion-Tr Smart and Orion XS series) provide a safe and efficient solution for LFP charging from alternators.

5.3. Discharging

The SuperPack NG battery can supply power to DC systems or inverters within the specified limits. The BMS continuously monitors voltage, current and temperature to ensure safe and reliable operation.

Discharge characteristics

  • The battery can deliver high discharge currents up to 2C, depending on the connected load and ambient temperature.

  • The BMS automatically disconnects the load when the low-voltage cut-off or temperature limits are reached.

  • Discharge is automatically re-enabled once the battery voltage or temperature returns to a safe level.

Discharge conditions

  • Discharging is only permitted when the battery temperature is between -30 °C and 60 °C. Outside this range, the BMS disables discharge to protect the cells.

  • When the battery is switched off via the VictronConnect app or the On/Off push button, discharging is disabled.

Recommended practices

  • Avoid deep discharges below 10 % SoC whenever possible.

  • Use the Low SoC warning level and Discharge floor settings to limit the depth of discharge. A reduced discharge depth improves battery longevity and maintains reserve capacity for backup power.

  • Regularly review discharge data in the VictronConnect history page to identify abnormal usage patterns.

  • During extended storage, disconnect all loads to prevent over-discharge caused by parasitic consumption. The best practice is to switch the battery off using the push button, as this also disables the internal Bluetooth interface.

5.4. Reset to factory defaults

The Lithium SuperPack NG battery can be reset to factory settings via the VictronConnect app.

How to reset:

  1. Open VictronConnect

  2. Tap the cogwheel icon to access Settings.

  3. Tap the three vertical dots in the Settings menu.

  4. Select Reset to defaults, then confirm with Yes.

The following settings will be restored to their default values:

  • Charged voltage

  • Tail current

  • Charged detection time

  • Low SoC warning level

  • Discharge floor
