7.6.5. Shunt current
When a shunt other than the one supplied with the battery monitor is used, use this setting to set the rated current of the shunt.
Setting Default Range Step size
Shunt current (setting 65) 500A 1 - 9999A 1A
7.6.6. Shunt voltage
When a shunt other than the one supplied with the battery monitor is used, use this setting to change the rated voltage of the
shunt.
Setting Default Range Step size
Shunt voltage (setting 66) 50mV 1 - 75mV 1mV
7.6.7. Temperature unit
This setting is available if the aux input has been set to "T
emperature", see the Aux input [40] setting.
Use this setting to select the temperature unit the battery monitor head unit is using.
Note that this setting only affects the battery monitor head unit display and settings. To change the temperature unit in the
VictronConnect app see Temperature unit setting [41].
Setting Default Modes
Temperature unit (setting 67) CELC CELC/FAHR
7.6.8. Temperature coefficient
This setting is available if the aux input has been set to "T
emperature", see the Aux input [40] 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

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 starts synchronised [30] chapter.
