2022 Interstate 24X 9-7
If the coach is not plugged into shore or generator
power, to charge the house batteries, the batteries
can go back into LBCO Mode soon after the vehicle’s
engine is turned off� Bringing the batteries out of LBCO
Mode is only “waking up” the batteries and allowing
them to take a charge� If wanting to use the generator
to charge, the vehicle’s engine will need to be ran for
several minutes before the house batteries are charged
enough to start the generator�
NOTE
If the batteries are in LBCO Mode and it is below
35°F, turn the “Battery Heater” switch to “ON”
before performing the wake up procedure.
NOTE
The BMS will not allow a charging current if the
internal temperature is below 25°F and it will not
allow a charging or discharging current above
135°F.
Battery State of Charge
The heated batteries consume an average of 1�8
amps� Testing indicates, that at 0°F, with no insulation,
the heater would be on about 30% of the time� With
no other loads or charging, the batteries would give
approximately 185 hours of heat capability before the
batteries would go into LBCO shutdown�

Cold Weather Usage
During the winter, lithium batteries will not take a
proper charge if the temperature is below 35°F�
To help prevent the batteries from reaching these
temperatures, an internal heating element has been
installed, which will engage when the temperature
drops below 35°F, if the key switch is turned ON�
The heating element will automatically engage and
disengage, depending on the temperature, and does
not require any user involvement�
The battery heaters key switch is located in the
overhead compartment behind the driver’s seat�
This key switch can be used to turn ON or OFF the
battery heaters� When storing your touring coach, it is
recommended the key switch be turned OFF to prevent
any parasitic battery draws from the heaters, while the
coach is in storage�
NOTE
It is recommended that the battery heater’s be
turned ON if the outside ambient temperature will
drop below 35°F.
