Connection
of
power
supply
and
receiver
The
SkyFire
LCU
allows
the
connection
of
1s/2s
Lipo
batteries,
2s
LiFePO
batteries,
3
‐
6s
NiMH
batteries
or
a
BEC
with
a
voltage
between
3.2
V
and
8.5
V
to
supply
the
LCU
as
well
as
the
9
light
channels
.
The
corresponding
supply
pin
of
the
MPX
connector
is
marked
with
“+LCU”.
The
operation
of
the
light
channels
is
most
efficient
at
1s
Lipo
(low
heating
of
the
resistors
and
very
low
system
weight).
The
additional
AUX
output
can
be
supplied
with
the
same
voltage.
For
this,
simply
connect
the
same
battery
to
the
appropriate
supply
pin,
marked
with
"
AUX”
.
Then
the
9
light
channels
and
AUX
output
carry
the
same
voltage.
However,
it
is
possible
to
connect
a
separate
battery
of
higher
voltage
up
to
13.0
V
to
the
supply
pin
of
the
AUX
output
(1s
/2s
/
3s
Lipo
batteries,
2s
/
3s
LiFePO
batteries,
3
‐
9s
NiMh
batteries
or
a
BEC
with
a
voltage
between
3.2
V
and
13.0
V).
This
allows
operation
of
afterburner
rings,
12V
LED
strips
or
other
external
consumers
with
higher
voltages,
while
it
would
not
make
sense
for
the
light
channels
1
‐
9
due
to
the
low
voltage
level
of
individual
LEDs.
IMPORTANT:
Voltages
up
to
13.0
V
supply
must
only
be
connected
to
the
AUX
output
(+AUX
)
and
not
to
the
LCU
itself
(+
LCU)!
The
maximum
operating
voltage
of
the
LCU
itself
(+
LCU)
is
8.5
V
Do
not
connect
any
other
battery
technologies
than
those
listed
above
to
the
SkyFire
LCU.
The
battery
type
used
must
be
absolutely
programmed
when
installing
the
SkyFire
LCU
to
allow
a
reliable
deep
discharge
and
battery
test
function,
see
"Programming
Mode"!
After
programming,
the
SkyFire
LCU
monitors
the
battery
and
protects
against
deep
discharge.
In
addition
the
battery
condition
can
be
checked
using
the
battery
test
function.
If
the
voltage
of
the
programmed
battery
is
critical,
the
SkyFire
LCU
turns
off
after
a
fast,
red
Flash
sequence
of
the
MODE
LED
(
Error
)
and
can
only
be
put
back
into
operation
by
again
pressing
the
power
button
If
different
batteries
with
different
voltage
levels
are
connected
to
the
supply
of
the
LCU
and
the
AUX
output,
both
batteries
will
be
monitored
after
successful
programming
!
The
following
instructions
must
be
observed
for
safe
operation.
‐
All
connecting
cables
should
be
routed
in
such
a
way
that
they
do
not
come
in
contact
with
moving
or
hot
parts
of
the
model
(e.g.
servos,
rods
or
silencers).
‐
The
SkyFire
LCU
must
be
protected
from
humidity
and
moisture.
