7.4. Miscellaneous settings
7.4.1. Temperature coefficient
This setting is available if the aux input has been set to "Temperature", see the
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.

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 [6]
7.4.3. Monitor Mode
If you wish to use the battery monitor to monitor individual DC circuits rather than as a whole-of-system battery monitor, you can
change the "Monitor mode" setting in the "Misc" menu from "Battery Monitor" to "DC Energy Meter".
If "DC meter" is selected, you can select the following types:
Solar charger, Wind charger, Shaft generator, Alternator, Fuel cell, Water generator, DC-DC charger, AC charger, Generic source,
Generic load, Electric drive, Fridge, Water pump, Bilge pump, DC system, Inverter, Water heater.
When connected to a GX device, the type, the current and the power is shown in the user interface, and this information is also
available on the VRM Portal.
When the GX device is also configured as type “has DC System”, the GX does more than just recording and visualisation:
1. The power shown in the DC system box is the sum of power reported by all battery monitors configured as such. Having
multiple meters can be useful, for example, in a catamaran, so that the DC systems in the port hull and in the starboard hull
are being measured.
2. The DC system current is being compensated for when setting DVCC charge current limits to inverter/chargers and solar
chargers. For example, when a load of 50A is being measured, and CCL by the battery is 25A, the limit given to the inverter/
charger or solar charger is 75A.
