Smart BatteryProtect 48V 100A

4. Operation and programming

In this section:

4.1. Operation modes

The Smart BatteryProtect has three operating modes, the appropriate mode can be selected via the VictronConnect app or a programming procedure (see chapter Programming).

  • Mode A: Buzzer or LED mode (default).

  • Mode B: Relay mode.

  • Mode C: Li-ion mode.

Modes A and B affect the behavior of the alarm output.

Mode C, the Li-ion mode, takes into account lithium batteries that have an external BMS or a BMS with load and/or charge disconnect.

Buzzer or LED mode behaviour

  • In case of under voltage, a continuous alarm will start after 12 seconds. The SBP will disconnect the load after 90 seconds and the alarm will stop. Reconnect delay: 30 seconds.

  • In case of over voltage, the load will be disconnected immediately and an intermittent alarm will remain on until the overvoltage problem has been corrected. There is no reconnect delay.

Relay mode behaviour

  • In case of under voltage, the relay will engage after 12 seconds. The SBP will disconnect the load after 90 seconds and the relay will disengage.

  • In case of over voltage, the load will be disconnected immediately and the alarm output will remain inactive.

Li-ion mode behaviour

Only select the Li-Ion mode if your BMS has a load disconnect and/or a charge disconnect output. This is usually not the case for so-called drop-in batteries with internal BMS. For lithium batteries/BMS without load disconnect output, select mode A or B instead.

Connect the load or charge disconnect (depending on application) output of the BMS to the Remote H terminal of the Smart BatteryProtect.

  • The load or charger is disconnected immediately when the load or charge disconnect output of the BMS switches from ‘high’ to ‘free floating’. The under voltage thresholds and alarm output of the Smart BatteryProtect are inactive in this mode.

  • It will remain disengaged for 30 seconds, even if it receives a re-engage signal within that time period. After 30 seconds it will respond immediately to a re-engage signal.

4.2. Programming

There are two ways to program a Smart BatteryProtect:

  • Via a Bluetooth enabled smartphone or tablet using our VictronConnect App.

  • or by connecting the PROG pin to GND pin method.

4.2.1. Programming via VictronConnect app

Programming via VictronConnect app

Requirements prior to programming::

  1. The battery positive must be connected to the IN terminal. Do not connect the OUT terminal yet.

  2. The included ground wire must be connected to the battery minus and the GND terminal of the Smart BatteryProtect.

Programming procedure:

  1. Open the VictronConnect app on your mobile device.

    All available Bluetooth devices are displayed.

  2. Select the Smart BatteryProtect from the Device list and tap on it.

    This will open the status screen, showing battery and load output state.

  3. Tap on the cog wheel in the top right corner.

  4. Check whether the detected battery voltage matches the system voltage.

  5. Select the operation mode (A, B or C - see the Programming table and Operation modes for details).

    In case of C (Li-ion), nothing further needs to be set.

  6. Choose between Relay and Buzzer/LED to set the alarm output.

  7. Set the preset to the desired combination of shutdown and restart voltage or tap on User defined to define a custom combination.

  8. In case of a user defined preset, tap on Shut down to set the shutdown voltage and tap on Restart to set the restart voltage.

  9. Click on the 3 dots in the top right corner and then on Product info.

  10. In the Product info menu the PIN code can be changed, a custom name can be set and Bluetooth can be disabled.

Note

If Bluetooth is disabled via the VictronConnect app, this process can only be reversed with programming via PROG pin procedure as explained in the next paragraph.

4.2.2. Programming via PROG pin to GND pin method

Requirements prior to programming:

  • The battery positive must be connected to the IN terminal. Do not connect the OUT terminal yet.

  • The included ground wire must be connected to the battery minus and the GND terminal of the Smart BatteryProtect 48V 100A.

  • The wire loop in the remote on/off terminal block must be removed.

Programming procedure:

  1. Use a wire loop or a wired switch (preferably a push button) between the PROG pin and the GND pin.

  2. While there is a connection between the PROG pin and the GND pin, the 7-segment display will first step through the shutdown and restart voltage combinations, as indicated by the numbers 0..9 (see the Programming table).

  3. Remove the wire loop or release the push button when the desired voltage mode is displayed.

  4. The display will confirm the chosen voltage and default mode (A) twice.

  5. Reconnect the wire loop or press the push button again, if a different operation mode (B, C or D) is required (see the Programming table).

  6. Disconnect the wire loop or release the push button when the required mode is displayed.

  7. The display will confirm the chosen voltage and operation mode twice.

The PIN code can be reset by selecting the P option. Bluetooth pairing information needs to be removed from any previously paired devices after selecting this option.

Bluetooth can be disabled/re-enabled by selecting F (enable) or H (disable).

4.3. Status indicator

The decimal point of the 7-segment display is used for status indication:

  • Illuminated: the Smart BatteryProtect is attempting to activate the output.

  • Flash every 5 seconds: output is active.

  • Flash every 2 seconds whilst in Li-ion mode: output ‘connecting’. When in Li-ion mode the SBP will observe a dead period of 30 seconds after the remote input of the SBP has become free floating.

4.4. Remote control and short circuit behavior

This section describes the behaviour of the Smart BatteryProtect when it is controlled via the remote on/off input and when a short circuit has been detected.

  • The Smart BatteryProtect will connect the load 1 second after the remote input is closed.

  • The Smart BatteryProtect will disconnect the load immediately when the remote input is opened.

  • When in Li-ion mode, the Smart BatteryProtect will observe a dead period of 30 seconds after the remote input of the Smart BatteryProtect has become free floating. See the note below for a detailed description.

  • In case of a short circuit, the Smart BatteryProtect will attempt to connect the load every 5 seconds. After two attempts the display will show E1 (short circuit detected).

Note

When in Li-ion mode, the SBP will disengage when the H input becomes free floating and will remain disengaged for 30 seconds, even if it receives a re-engage signal within that time period. After 30 seconds it will respond immediately to a re-engage signal. Therefore, there will normally be no waiting time if the SBP is used as a system on/off switch (wire the system on/off switch to the positive supply of the BMS for this purpose).

Similarly, if a system shutdown occurred due to low cell voltage, the SBP will remain disengaged for 30 seconds, even if it receives a re-engage signal within that time period (which most likely will happen when no other loads are connected to the battery). After 3 attempts to re-engage, the SBP will remain disengaged until battery voltage has increased to more than 52V for at least 30 seconds (which is a sign that the battery is being recharged). The under voltage thresholds and alarm output of the SBP are inactive in this mode.

4.5. Error & Warning modes

There are 9 possible error modes and 2 warning codes, indicated by the 7-segment display and within the VictronConnect app when using a Bluetooth enabled smartphone or tablet:

  • E0 Calibration failure

  • E1 Short circuit

  • E2 Over temperature / P2 Over temperature warning

  • E3 Under voltage / P3 Under voltage warning

  • E4 Over voltage

  • E5 Configuration Failure

  • E6 Reference Voltage Failure

  • E7 BMS Lockout

  • E8 Reverse current

  • P2 Over temperature warning

  • P3 Under voltage warning

After 5 minutes the error is no longer displayed to reduce current consumption.

Please refer to the appendix chapter Error and Warning codes for more info on each error.
