battery
monitor
is
used
to
monitor
the
house
and
the
starter
batteries.
To

Capacity
on
the

Lithium
batteries
voltage
will
stay
>
13V
throughout
their
discharge
(unlike
Lead
Acid/AGM).
Reading
the
State
of
Charge
is
the
best
way
to
monitor
the
battery.
The
battery
monitor
also
estimates
how
long
the
battery
can
support
the
present
load:
the
‘time

to
‐
go’
readout.
This
is
the
actual
time
left
until
the
battery
is
discharged
to
the
discharge
floor.
The
fridge,
freezer,
and
Webasto
heating
system
(as
well
as
anything
using
the
inverter
(microwave))
all
have
significant
effect
on
the
battery
life.
Ideally
get
the
fridge
and
freezer
down
to
temp
on
shore
power
or
while
motoring
and
turn
them
off
while
sailing
or
at
anchor.
We
typically
turn
the
heating
system
off
at
night.

NVERTER
The
boat
has
a
3KW
inverter
providing
110V
power
from
the
house
battery.
Be
careful
as
it
is
easy
to
draw
the
batteries
down
fast.
We
suggest
leaving
the
inverter
turned
to
“charger
only”
unless
you
need
110V
power;
the
main
risk
is
running
the
house
batteries
low
without
realizing
it.

The
current
limit
displayed
on
the
charger/inverter
panel
is
the
number
of
Amps
(at
110V
AC)
and
it
should
not
exceed
the
capacity
of
the
shore
power
circuit,
including
the
shore
power
cable
in
use.
We
recommend
30A
Max
for
the
charger.
