It’s
liable
to
harm

or
even
cause
heat
run
away
when
heat
accumulates.
If
temperature
is
too
high,
it
must
decrease
temperature
by
using
air
conditioner
or
providing
good
ventilation.
Please
leave
over
10mm
between
batteries
and
the
ground.
Meanwhile,
adjust

1)
First
confirm
end
voltage.
e.g.,
required
end
voltage
is
1.80V/cell.
2)
Confirm
the
continual
working
time
and
discharge
current.
E.g.,
the
continual
working
time
is
3
hours,
and
the
discharge
current
is
125A
.You
should
choose
the
minimum
capacity
is
7OPzV

3)
Confirm
the

When
the
ambient
temperature
is
25
℃
,
you
should
choose
7OPzV

Or
you
should
confirm
the

according
to
the
Fig.3

If
the
temperature
is
below

℃
,
there
leaves
80%

compared
with

.Then
you
should

4)
To
ensure
the
life
of
the
battery,
please
do
not
discharge

too
much.
You'd
better
control
the
DOD
below
the
80%,
especially
in
the
power

areas.
There
should
be
some
surplus

after
each
discharge
to
prevent
from

term
insufficient

which
gives
harm
to

Equalization
Charge
The
battery
need
an
equalization
charge
in
the
following
conditions:
a.
The
float
voltage
of
over
two
batteries
are
lower
than
2.18V.
b.
Floating
operation
for
three
months.
The
method
of
equalization
charge
is
suggested
as
follows:
Charge
the
battery
group
on
the
constant
current
of
0.1C10A
～
0.15C10A.
When
the
average
voltage
up
to
the
equalization
voltage,
the
charging
current
will
decrease
automatically.
