What
are
the
effects
of
temperature
on
capacity
and
operation
for
both
high
(120
‐
140
˚
F)
and
low
temperatures
(0
‐
20
˚
F)?
The
supported
discharge
temperature
range
is
‐
4
˚
F
to
140
˚
F
and
supported
charge
range
is
32
˚
F
to
140
˚
F.
At
140
˚
F
the
available
capacity
is
100%,
at
32
˚
F
there
is
75%
available
capacity,
and
at
‐
4
˚
F
there
is
41%
available
capacity.
Constant
operation
at
140
˚
F
may
reduce
the
battery
cycle
lifetime
by
10
‐
20%.
Is
the
temperature
range
of
‐
20C
to
60C
(
‐
4F
to
140F)
the
operating
internal
temperature
of
the
pack
or
the
ambient
temperature?
This
is
the
internal
operating
temperature.
There
are
temperature
sensors
inside
the
pack
which
monitor
the
operating
temperature.
If
the
temperature
range
is
exceeded,
the
buzzer
will
sound
and
the
pack
will
automatically
shut
off
until
the
pack
is
allowed
to
cool/heat
to
within
operational
parameters.
What
is
the
temperature
increase
during
use
of
Flux
LiFT
Packs
compared
to
Lead
‐
Acid?
Flux
LiFT
Packs
experience
minimal
temperature
increase
during
charging
and
discharging.
Tests
run
by
Flux
Power
indicate
flooded
lead
‐
acid
temperatures
increase
27%
more
and
AGM
increase
47%
more
than
Flux
LiFT
packs
during
a
1
hour
complete
discharge.
This
is
due
to
the
lower
internal
resistance
of
lithium
‐
ion
vs.
lead
‐
acid,
and
means
the
battery
wastes
less
energy
when
charging
and
discharging.
CHARGER
/
CHARGING
Can
Flux
LiFT
Packs
TM
be
opportunity
charged?
Yes,
Flux
LiFT
Packs
can
be
plugged
in
at
any
state
of
charge
with
absolutely
no
negative
effects.
In
fact,
opportunity
charging
can
actually
increase
the
lifetime
amp
‐
hour
output
of
the
battery.
The
pack
does
need
periodic
balancing
however,
and
we
recommend
leaving
it
plugged
in
overnight
or
over
the
weekend
once
every
week
or
two.
What
happens
when
the
pack
runs
out
of
charge?
When
the
battery
reaches
5%
SOC
a
beeper
will
sound
notifying
the
operator
that
the
battery
must
be
charged.
Once
the
battery
reaches
1%
SOC
the
beeper
will
sound
again,
notifying
the
operator
again.
Finally
it
will
cut
power
intermittently
and
allow
the
pallet
jack
to
be
slowly
driven
to
a
charging
point.
We
recommend
plugging
the
pack
in
as
soon
as
the
initial
buzzer
sounds
to
prolong
the
life
of
the
battery.
If
the
pack
is
not
plugged
in
and
left
sitting
in
an
uncharged
state,
it
is
possible
the
lithium
cells
will
be
permanently
damaged
and
no
longer
function.
Do
I
need
to
disconnect
the
LiFT
Pack
from
the
walkie/pallet
jack
to
charge
it?
If
the
LiFT
Pack
has
an
internal
charger
it
does
not
need
to
be
disconnected
from
the
walkie
to
charge
it.
However,
please
be
aware
that
the
pallet
jack
will
be
operational
while
charging
so
it’s
recommended
the
Anderson
power
connector
be
disconnected.
