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.

.
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.

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%.

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.

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%.

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.

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.

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.

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.

Battery SOC on reset
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:
Keep SOC - The state of charge is set to its last known value. This is the default mode. In this mode, the battery monitor regularly stores the state of charge and, after losing power, resumes from the last known state of charge.
Clear - The state of charge remains unknown until the synchronization levels are reached and synchronization occurs.
Set to 100% - The state of charge is set to 100%.

Set to 100%
This setting is only available when the battery monitor's firmware is version 4.12 or higher and the Bluetooth interface's firmware is version 2.42 or higher.
In case the battery monitor or Bluetooth interface firmware is older, this setting is called "Start synchronized" and offers the option to either turn it OFF (clear) or ON (set to 100%).

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.

See the Manual synchronisation paragraph for more information on this setting.
7.2.13
.
Zero current calibration
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 SYSTEM MINUS 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 CALIBRATE in the VictronConnect app.
