Battery 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�

Temperature Limits

• The battery has an operating temperature range of
-4°F (-20°C) to 135°F (57�2°C)�
• The BMS will not allow a charging current under
25°F (-3�9°C) but will continue to discharge down
to -4°F (-20°C)�
• The BMS will not allow a charging or discharging
current if the internal temperature of the battery
has reached 135°F (57�2°C)

Cold Weather Usage

The house batteries have internal heaters that will
engage when the battery temperature drops below
35°F (when the battery disconnect switch is ON)�
Depending on the temperature, the heating element
will automatically engage and disengage and does not
require any user input�
NOTE
The BMS will not allow a charging current if the
internal temperature is below 25°F, and it will
not allow charging or discharging current above
NOTE
If the battery is in low-voltage disconnect mode
and the battery temperature is below 35°F, the
heat function will need some time to warm the
battery before performing the wake-up procedure.
