Connection
of
Supply
and
Receiver
The
AURORA
LCU
EV
2
O
is
powered
by
1s/2s/3s
Lipo
Batteries,
2s/3s
LiFePO
Batteries,
3
‐
10s
NiMh
Batteries
or
with
a
BEC
Voltage
between
3,2V
und
13,0V.
The
PLUS
supply
line
ist
red
,
the
MINUS
line
is
marked
by
a
black
line.
The
most
efficient
operation
(Least
power
dissipation
at
resistors
and
lowest
system
weight)
works
with
1s
cell
Lipo.
Attention:
1s
LiFePO
batteries
are
not
recommended
for
powering
Power
LEDs
(1Watt
/
3Watt)
because
the
little
lower
battery
voltage
means
a
lower
brightness
of
LEDs.
The
used
battery
‐
type
has
to
be
programmed
at
first
use
of
the
AURORA
LCU
EV
2
O
to
offer
a
reliable
deep
‐
discharge
‐
protection
and
battery

function,
see
“Programming
Mode”.
After
programming,
the
used
battery
will
be
protected
and
the
batteries
condition
can
be
checked
with
battery
‐
test
function
of
the
AURORA
LCU
EV
2

.
Do
not
connect
other

technologies
to
the
AURORA
LCU
EV

.
The
factory
setting
of
the
AURORA
LCU
EV
2
O
is
BEC
Supply,
that
means
the
supply
is
NOT
protected
for
low
voltage!
If
the
programmed
battery
voltage
becomes
critical,
the
AURORA
LCU
EV
2
O
shuts
down
after
a
fast
flashing
‐
sequence
of
the
green
Info
LED
(Error)
and
can
only
be
restarted
by
reconnecting
the
battery

‐
All
wires
and
components
have
to
be
installed
in
a
proper
way,
with
distance
to
hot
and
moving
parts
of
the
model.

The
AURORA

Battery
Recommendation
Following
battery
capacities
are
recommended
for
one
hour
operation
of
one
LED
on
each
of
the
six
outputs.
If
LEDs
are
operated
with
flash
sequences,
capacity
can
be
accordingly
smaller.

Connetion
of
Battery
The
battery
is
connected
at
the
two
silicon
wires
(
red
/
black
or
black
line)
with
JR
plug
,
see
Labeling
Supply
.
Be
sure
to
pay
attention
to
proper
polarity:
RED
=
PLUS
,
BLACK
=
MINUS
.
The
AURORA
LCU
EV

is
not
protected
against
reverse
polarity!
