Temperature Compensation Coefficient
The setting range of temperature compensation coefficient is 0 to 2500mV/°C and it should be set according to the
actual battery parameter.
The battery is sensitive to the change of ambient temperature. In order to ensure the battery capacity and life, when
ambient temperature changes, the battery float charge voltage also changes. The Float Charge Voltage is the
normally the voltage when the room temperature is 25°C. The higher the ambient temperature is, the lower the Float
Charge Voltage is, and vice versa. For the battery with 2 V battery cells, the Float Charge Voltage for every cell will
be decreased by 3 to 7mV when the ambient temperature is increased by every 1°C. Therefore, the “Compensation
Factor” for 48V battery shall be set to 72mV to 168mV, and the “Compensation Factor” for 24V battery shall be set to
36 to 84mV/°C.

LLVD: The M800D disconnects the LLVD contactor, thus the non-priority load controlled by the contactor will be
powered off so that the battery can power the priority load longer. If the “LLVD Enable” is set to “Yes”(factory setting),
monitoring module will enable the auto LLVD function.
BLVD: The M800D disconnects the BLVD contactor. Thus the battery will not continue to power the load so as to
prevent its life from being reduced due to over discharging. If the “BLVD Enable” is set to “Yes”(factory setting),
monitoring module will enable the auto BLVD function.
