Leisure battery. If the leisure

Notes
This cut off level is designed
to protect the vehicle battery
from over discharge. The
10.9v level ensures there
is sufficient power in the
battery to run the vehicle
electronics and start the
vehicle. This cut off only
applies to power drawn from
the battery by the leisure
equipment; it will not protect
the battery if you leave
vehicle circuits switched on,
such as the road lights.
This is an emergency cut off
level to protect the battery
from severe damage. You
should not rely on this
cut off level during normal
operation, but manage your
power consumption to a
discharge level of 10v.
This cut off only applies
to power drawn from
the battery by the leisure
equipment that is controlled
by the control panel power
switch; it will not protect
the battery from discharge
by permanently connected
equipment.
