7. All features and settings
This chapter explains all battery monitor settings. In addition to this we also have a video available explaining these settings and how the interact with each other to achieve accurate battery monitoring for both lead acid and lithium batteries.
Link to the video:
7.1. How to change settings
Settings can be changed by using the battery monitor's head unit or by using the VictronConnect app.
7.1.1. Accessing settings via the head unit
To access and change setting parameters use the buttons on the head unit in the following way:
Press SETUP for two seconds to access these functions and use the+ and – buttons to browse them.
Press SELECT to access the desired parameter.
Use SELECT and the + and – buttons to customize. A short beep confirms the setting.
Press SETUP at any time to return to the scrolling text, and press again to return to normal mode.
7.1.2. Accessing settings via the VictronConnect app
To access and change setting parameters do the following:
Click on the settings symbol
to go to the battery settings menu.
To navigate from the general settings menu to the product settings menu, click on the menu symbol
.
For information on how to connect with the VictronConnect app to the battery monitor, see the The VictronConnect app chapter.
7.1.3. Saving, loading and sharing settings in VictronConnect
In the settings menu you can find the following 3 symbols:
Save settings to file - This will save settings for reference or for later use.
Load settings from file - This will load earlier saved settings.
Share settings file – This allows you to share the settings file via email, message, airdrop and so on. The available sharing options depend on the platform used.
For more information on these features, see the VictronConnect manual.
7.2. Battery settings
The battery settings can be used to fine-tune the battery monitor. Please be careful when you change these settings, as a change might affect the battery monitor's state of charge calculations.
7.2.1. Battery capacity
This parameter is used to tell the battery monitor how big the battery is. This setting should already have been done during the initial installation.
The setting is the battery capacity in Amp-hours (Ah).
For more information on the battery capacity and the related Peukert exponent see the Battery capacity and Peukert exponent chapter.
Setting | Default | Range | Step size |
---|---|---|---|
Battery capacity (setting 01) | 200Ah | 1 - 9999Ah | 1Ah |
7.2.2. Charged voltage
The battery voltage must be above this voltage level to consider the battery as fully charged. As soon as the battery monitor detects that the voltage of the battery has reached this “charged voltage” parameter and the current has dropped below the “tail current” parameter for a certain amount of time, the battery monitor will set the state of charge to 100%.
Setting | Default | Range | Step size |
---|---|---|---|
Charged voltage (setting 02) | 13.2V (12V nominal) 26.4V (24V nominal) 52.8V (48V nominal) | 0 - 95V | 0.1V |
The “charged voltage” parameter should be set to 0.2V or 0.3V below the float voltage of the charger.
The table below indicates the recommended settings for lead acid batteries.
Nominal battery voltage | Charged voltage setting |
---|---|
12V | 13.2V |
24V | 26.4V |
36V | 39.6V |
48V | 52.8V |
60V | 66V |
7.2.3. Discharge floor
The “Discharge floor” parameter is used in the "time remaining" calculation. The battery monitor calculates the time it takes until the set “discharge floor” has been reached. It is also used to set the state of charge alarm defaults.
For lead-acid batteries set this to 50% and for lithium set it lower.
Note that this setting only appears when accessing the battery monitor via the VictronConnect app. In case the battery monitor is accessed via the head unit, see the Low State of Charge (SoC) relay setting instead.
Setting | Default setting | Range | Step size |
---|---|---|---|
Discharge floor | 50% | 0 - 99% | 1% |
7.2.4. Tail current
The battery is considered as fully charged once the charge current has dropped to less than this “Tail current” parameter. The “Tail current” parameter is expressed as a percentage of the battery capacity.
Note that some battery chargers stop charging when the current drops below a set threshold. In these cases, the tail current must be set higher than this threshold.
As soon as the battery monitor detects that the voltage of the battery has reached the set “Charged voltage” parameter and the current has dropped below this “Tail current” parameter for a certain amount of time, the battery monitor will set the state of charge to 100%.
Setting | Default | Range | Step size |
---|---|---|---|
Tail current (setting 03) | 4.00% | 0.50 - 10.00% | 0.1% |
7.2.5. Charged detection time
This is the time the “Charged voltage” parameter and the “Tail current” parameter must be met in order to consider the battery fully charged.
Setting | Default setting | Range | Step size |
---|---|---|---|
Charged detection time (setting 04) | 3 minutes | 0 - 100 minutes | 1 minute |
7.2.6. Peukert exponent
Set the Peukert exponent parameter according to the battery specification sheet. If the Peukert exponent is unknown, set it at 1.25 for lead-acid batteries and set it at 1.05 for lithium batteries. A value of 1.00 disables the Peukert compensation. The Peukert value for lead-acid batteries can be calculated. For more information on the Peukert calculation, the Peukert exponent and how this relates to the battery capacity, see the Battery capacity and Peukert exponent chapter.
Setting | Default | Range | Step size |
---|---|---|---|
Peukert exponent (setting 05) | 1.25 | 1.00 - 1.50 | 0.01 |
7.2.7. Charge efficiency factor
The “Charge Efficiency Factor” compensates for the capacity (Ah) losses during charging. A setting of 100% means that there are no losses.
A charge efficiency of 95% means that 10Ah must be transferred to the battery to get 9.5Ah actually stored in the battery. The charge efficiency of a battery depends on battery type, age and usage. The battery monitor takes this phenomenon into account with the charge efficiency factor.
The charge efficiency of a lead acid battery is almost 100% as long as no gas generation takes place. Gassing means that part of the charge current is not transformed into chemical energy, which is stored in the plates of the battery, but is used to decompose water into oxygen and hydrogen gas (highly explosive!). The energy stored in the plates can be retrieved during the next discharge, whereas the energy used to decompose water is lost. Gassing can easily be observed in flooded batteries. Please note that the ‘oxygen only’ end of the charge phase of sealed (VRLA) gel and AGM batteries also results in a reduced charge efficiency.
Setting | Default setting | Range | Step size |
---|---|---|---|
Charge efficiency factor (setting 06) | 95% | 50 - 100% | 1% |
7.2.8. Current threshold
When the current measured falls below the “Current threshold” parameter it will be considered zero. The “Current threshold” is used to cancel out very small currents that can negatively affect the long-term state of charge readout in noisy environments. For example, if the actual long-term current is 0.0A and, due to injected noise or small offsets, the battery monitor measures 0.05A the battery monitor might, in the long term, incorrectly indicate that the battery is empty or will need to be recharged. When the current threshold in this example is set to 0.1A, the battery monitor calculates with 0.0A so that errors are eliminated.
A value of 0.0A disables this function.
Setting | Default | Range | Step size |
---|---|---|---|
Current threshold (setting 07) | 0.10A | 0.00 - 2.00A | 0.01A |
7.2.9. Time-to-go averaging period
The time-to-go averaging period specifies the time window (in minutes) that the moving averaging filter works. A value of 0 (zero) disables the filter and gives an instantaneous (real-time) readout. However, the displayed “Time remaining” value may fluctuate heavily. Selecting the longest time, 12 minutes, will ensure that only long-term load fluctuations are included in the “Time remaining” calculations.
Setting | Default | Range | Step size |
---|---|---|---|
Time-to-go averaging period (setting 08) | 3 minutes | 0 - 12 minutes | 1 minute |
7.2.10. Battery SOC on reset
Notice
Note that if you access this setting through the head unit, this setting will be categorized under "Miscellaneous settings". However, when accessed via the VictronConnect app, it falls under "Battery settings".
This setting determines the behaviour of the state of charge (SOC) value following a battery monitor reset. A reset occurs when the battery monitor is powered down and subsequently powered up again. This occurs during initial installation or disconnection, such as on a boat when the DC system is disconnected via the main DC breaker.
The "Battery SOC on reset" setting has the following modes:
Clear - The state of charge remains unknown until the synchronization levels are reached and synchronization occurs. This is the default mode.
Set to 100% - The state of charge is set to 100%.
Setting | Default | Modes |
---|---|---|
Battery SOC on reset (setting 70) | Clear | Clear Set to 100% |
7.2.11. State of charge
With this setting, you can manually set the state of charge value. This setting is only active after the battery monitor has, at least once, been synchronised. Either automatically or manually.
This setting is only available when accessing the battery monitor via the VictronConnect app.
Setting | Default | Range | Step size |
---|---|---|---|
State of charge | -- % | 0.0 - 100% | 0.1% |
7.2.12. Synchronise SoC to 100%
Setting 10
This option can be used to manually synchronise the battery monitor.
When navigating to this setting on the head unit , press the SELECT button to synchronize the battery monitor to 100%.
In the VictronConnect app press the ”Synchronise” button to synchronise the battery monitor to 100%.
See the Manual synchronisation paragraph for more information on this setting.
7.2.13. Zero current calibration
Setting 09
This option can be used to calibrate the zero reading if the battery monitor reads a non-zero current even when there is no load and the battery is not being charged.
A zero current calibration is (almost) never needed. Only perform this procedure in case the battery monitor shows a current while you are absolutely sure that there is no actual current flowing. The only way to be sure is to physically disconnect all wires and cables connected to the LOAD AND CHARGER side of the shunt. Do this by unscrewing the shunt bolt and removing all cables and wires from that side of the shunt. The alternative, switching loads or chargers off, is NOT accurate enough as this does not eliminate small standby currents.
Ensure that there really is no current flowing into or out of the battery (disconnect the cable between the load and the shunt), then press SELECT in the head unit menu or press CALIBRATE in the VictronConnect app.

Performing a zero current calibration.
7.3. Relay settings
The battery monitor is equipped with a programmable relay. These settings are used to program the function of the relay.
The relay settings are disabled by default (except the State of Charge (SoC) relay setting). To enable, a relay setting do the following:
In the VictronConnect app, enable the relay setting by sliding the slider button to the right.
Via the head unit, enable the relay setting by changing the set and clear value to any value above zero.
7.3.1. Relay mode
This setting has the following relay modes, namely:
Setting | Default mode | Modes | Description |
---|---|---|---|
Relay mode (setting 11) | DFLT | DFLT Default mode. | The relay settings 16 up to 31 can be used to control the relay. |
CHRG Charger mode. | The relay will close when the state of charge falls below setting 16 (discharge floor) or when the battery voltage falls below setting 18 (low voltage relay). The relay will be open when the state of charge is higher than setting 17 (clear state of charge relay) and the battery voltage is higher than setting 19 (clear low voltage relay). An application example is to start and stop control of a generator, together with settings 14 and 15. | ||
REM Remote mode. | The relay can be controlled via the VE.Direct interface. Relay settings 12 and 14 up to 31 are ignored as the relay is under the full control of the device connected via the VE.Direct interface. |
7.3.2. Invert relay
This function enables selection between a normally de-energised (contact open) or a normally energised (contact closed) relay.
When inverted, the open and closed conditions as described in all the relay settings are inverted (with the exception of the Relay state).
Note that the "normally energised" setting will slightly increase the power consumption of the battery monitor.
Setting | Default mode | Modes | Range |
---|---|---|---|
Invert relay (setting 12) | OFF | OFF | Normally de-energised |
ON | Normally energised |
7.3.3. Relay state
This is a read-only parameter and it displays whether the relay is open or closed (de-energised or energised).
Setting | Value | Description |
---|---|---|
Relay state (setting 13) | OPEN | The relay is open (de-energised) |
CLSD | The relay is closed (energised) |
7.3.4. Relay minimum closed time
Sets the minimum time the "closed" condition will remain present after the relay has been energised.
Note that this changes to "open" and de-energised if the relay function has been inverted (Invert relay setting).
An application example is to set a minimum generator run time when the relay is set to "charger" mode (Relay mode setting).
Setting | Default | Range | Step size |
---|---|---|---|
Relay minimum closed time (setting 14) | 0 minutes | 0 - 8 hours | 1 minute |
7.3.5. Relay off delay

An application example is to keep a generator running for a while to charge the battery better when the relay is set to "charger" mode (Relay mode setting).
Setting | Default | Range | Step size |
---|---|---|---|
Relay off delay (setting 15) | 0 minutes | 0 - 500 minutes | 1 minute |
7.3.6. Low State of Charge (SoC) relay
When the state of charge percentage has fallen below the "set relay" value, the relay will close.
When the state of charge percentage has risen above the "clear relay" value, the relay will open (after a delay, depending on the Relay minimum closed time and/or the Relay off delay settings).
The "clear relay" value needs to be greater than the "set relay" value.
Setting | Default | Range | Step size |
---|---|---|---|
Set relay value (setting 16) | 50% | 0 - 99% | 1% |
Clear relay value (setting 17) | 90% | 0 - 99% | 1% |
Notice
When the "set relay" and "clear relay" values are equal, the state of charge condition will be unable to drive the relay.
Note
Note that this setting is also known as the discharge floor. The time-to-go reading displayed by the battery monitor relates to this setting. The time to go is the time left until this setting (the discharge floor) has been reached.
7.3.7. Low voltage relay
When the battery voltage falls below the "set relay" value for more than 10 seconds the relay will close.

7.6.8. Temperature coefficient
This setting is available if the aux input has been set to "Temperature", see the Aux input setting.
The available battery capacity decreases with temperature. The temperature coefficient (delta T) is the percentage the battery capacity changes with temperature when temperature decreases to less than 20°C (above 20°C the influence of temperature on capacity is relatively low and is not taken into account). Typically, the reduction, compared to the capacity at 20°C, is 18% at 0°C and 40% at -20°C.
The unit of this value is “%cap/°C” or per cent capacity per degree Celsius.
The typical value (below 20°C) is 1%cap/°C for lead acid batteries, and 0.5%cap/°C for LFP batteries.
Setting | Default | Range | Step size |
---|---|---|---|
Temperature coefficient (setting 68) | 0.0%cap/°C 0.0%cap/°F | 0 - 2.0%cap/°C 0 - 3.6%cap/°F | 0.1%cap/°C 0.1%cap/°F |
7.6.9. Aux input
This setting sets the function of the auxiliary input. Select between: None, Starter battery, Midpoint or Temperature.
Setting | Default | Modes | Description |
---|---|---|---|
Aux input (setting 69) | NONE | NONE | Disables the auxiliary input. |
START | Auxiliary voltage, e.g. a starter battery | ||
MID | Midpoint voltage | ||
TEMP | Battery temperature. Note that a special temperature sensor is needed. For more information see: Auxiliary connection for temperature monitoring |
7.6.10. Battery starts synchronised
Note that if the battery monitor settings are accessed via the head unit, this setting will be part of the miscellaneous setting, and if accessed via VictronConnect it will be part of the battery settings.
For full information about this setting see the Battery SOC on reset chapter.
Setting | Default | Modes |
---|---|---|
Start synchronized (setting 70) | ON | ON/OFF |
7.7. Additional settings
These VictronConnect settings are not located in the VictronConnect settings menu but are located elsewhere in the VictronConnect app.
7.7.1. Reset history
This setting can be found at the bottom of the history tab.
This setting can also be made via the head unit. For more information see the Clear historychapter.
Caution
Please be aware that history data is an important tool to keep track of battery performance and is also needed to diagnose possible battery problems. Do not clear the history unless the battery bank is replaced.
7.7.2. Reset PIN code
Note that the PIN code is only applicable when connecting to the battery monitor via Bluetooth.
This setting can be found in the settings of the VictronConnect app itself. Leave the battery monitor by clicking on the ← arrow. This will bring you back to the device list of the VictronConnect app. Now, click on the menu symbol next to the battery monitor listing.
A new window will open which allows you to reset the PIN code back to its default: 000000. To be able to reset the PIN code you will need the enter the battery monitor unique PUK code. The PUK code is printed on the product information sticker on the Battery monitor.
7.7.3. Temperature unit setting
This setting can be found in the settings of the VictronConnect app itself. Leave the battery monitor page by clicking on the ← arrow. This will bring you back to the device list of the VictronConnect app. Click on the menu symbol and then click on the settings
symbol. Here you can select the “Display temperature unit”. Selecting Celsius will display the temperature in °C and selecting Fahrenheit will display the temperature in °F.
7.7.4. Serial number
The serial number can be found in the battery monitor product info section of the VictronConnect app or on the product information sticker rear of the battery monitor head unit.
7.7.5. Custom name
In the battery monitor product information screen, you can change the name of the battery monitor. By default, it is called by its product name. But a more applicable name might be needed, especially if you are using multiple battery monitors in close proximity of each other it might become confusing with which battery monitor you are communicating. You can, for example, add identification numbers to their name, like: Battery Monitor A, Battery Monitor B and so on.
7.7.6. Firmware
The battery monitor runs on firmware.
Occasionally a newer firmware version is available. New firmware is released to either add features or to fix a bug. The product overview in the VictronConnect app displays the battery monitor firmware version. It also indicates whether the firmware is the latest version, and there is a button you can press to update the firmware.
On the first installation, it is always recommended to update to the most recent firmware (if available). Whenever you connect to the battery monitor with an up-to-date version of the VictronConnect app, it will check the firmware, and if there is a newer version available, it will ask you to update the firmware. The VictronConnect app contains the actual firmware files, so an internet connection is not needed to update to the most recent firmware as long as you are using the most up-to-date version of the VictronConnect app.
A firmware update is not mandatory. If you choose not to update the firmware, you can only read out the battery monitor, but you cannot change settings. Settings can only be changed if the battery monitor runs on the most recent firmware.
For more information on firmware updates also see the VictronConnect app manual Firmware update chapter.
This setting is also available via the head unit Software version setting. But note that this is a read-only setting. The firmware cannot be updated via the head unit.
7.7.7. Reset to defaults
To set all settings back to default select “Reset to defaults”. Please note that this only resets all settings to their default values, the history is not reset.
This setting is also available via the head unit. For more information see the Restore defaults chapter.
