NOTE:
It’s
safer
and
better
for
the
longevity
of
the
battery
to
store
it
only
partially
charged
for
any
length
of
time.
Storing
the
battery
at
approximately
50%
charge
(which
is
approximately
3.85V
per
cell)
is
typically
best;
however,
it
will
take
some
careful
management
of
the
charge
time
and
the
use
of
a
volt
meter
to
achieve
this
voltage.
If
you
have
the
equipment
and
skills
to
achieve
the
50%
charge
level
for
storage
it
is
recommended.
If
not,
simply
be
sure
to
not
store
the
battery
fully
charged
whenever
possible.
In
fact,
as
long
as
the
battery
will
be
stored
at
approximately
room
temperature
and
for
no
more
than
a
few
weeks
before
the
next
use,
it
may
be
best
to
store
the
battery
in
the
discharged
state
after
the
last
flight
(as
long
as
the
battery
was
not
over
‐
discharged
on
the
last
flight).
Charge
Errors
and
Indications
In
the
event
that
both
the
red
and
green
LEDs
flash
an
error
has
occurred
during
the
charge
process.
Some
examples
of
charge
errors
and
their
indications
include:
•
Alternating
flashing
of
the
red
and
green
LEDs
indicates
that
the
charge
process
has
been
interrupted.
If
input
power
to
the
charger
has
been
interrupted
due
to
a
drop
in
voltage/current
output
or
disconnection
from
the
power
source
disconnect
the
battery
from
the
charger.
Check
to
make
sure
that
the
input
power
plug
from
the
AC
adapter/power
supply
is
connected
or
that
the
alligator
clips
are
firmly
and
properly
attached
to
the
power
source.
You
should
also
check
to
be
sure
that
the
power
source
is
providing
the
proper
amount
of
voltage
and
current
required
to
power
the
charger
reliably.
After
confirming
the
input
power
connection
is
secure
and
that
the
power
source
is
delivering
the
necessary
voltage
and
current,
connect
the
battery
to
the
charger
again.
Continue
to
monitor
the
charge
process
to
ensure
that
no
further
charge
errors
occur.
•
Simultaneous
flashing
of
the
red
and
green
LEDs
indicates
that
the
voltage
of
the
LiPo
battery
(or
even
just
one
cell
in
the
battery)
is
too
low
to
allow
the
charge
process
to
begin.
In
this
case
the
battery
may
have
been
over
‐
discharged
due
to
flying
the
model
too
long
(please
see
the
‘LiPo
Battery
Warnings
and
Usage
Guidelines’
section
of
this
manual
for
more
information)
or
that
one
or
more
cells
in
the
battery
are
damaged/have
failed.
NOTE:
If
you
continue
to
see
this
charge
error
indication
after
attempting
to
charge
the
same
battery
multiple
times
you
should
remove
the
battery
from
service
and
replace
it
with
a
new
one.
