68. Temperature Coecient
This is the percentage the battery capacity changes with temperature when temperature decreases to less than
20°C (above 20°C the inuence of temperature on capacity is relatively low and is not taken into account). The unit
of this value is “%cap/°C” or percent capacity per degree Celsius. The typical value (below 20°C) is 1%cap/°C for
lead acid batteries and 0.5%cap/°C for Lithium Iron Phosphate batteries.
Default Range Step size
0%cap/°C 0-2%cap/°C 0.1%cap/°C
69. Aux Input
Sets the function of the auxiliary input:
START - Auxiliary voltage, e.g. a starter battery.
MID - Mid-point voltage.
TEMP - Battery temperature.
66. Shunt Voltage
When using a shunt other than the one supplied with the BMK, set to the rated voltage of the shunt.
Default Range Step size
50mV 1mV-75mV 1mV
5.3 HISTORY DATA
The GP-BMK-50 tracks several parameters regarding the state of the battery which can be used to evaluate usage
patterns and battery health.
Enter history data by pressing the SELECT button when in normal mode.
Press + or - to browse the various parameters.
Press SELECT again to stop scrolling and show the value.
Press + or - to browse the various values.
Press SELECT again to leave the historical menu and go back to normal operation mode.
