Shorai LFX Manual

Do not throw away the box or any
foam packaging until after
installation is complete!!

CAUTIONS
 Do not short terminals together!
 Do not short, nor attach anything to the 5-pin
BMS port except Shorai BMS01 Chargers.
 Do not open or damage the battery case
 Use anti-corrosion spray on terminals during
use in salty and/or wet environments
 Keep batteries away from pets and children
 Do not allow discharge below 13.0V
(resting 13.0V for 12V types, 6.5V for 6V types)
 Do not allow charge voltage in excess of
14.8V
(7.4V for 6V types)
 Lead-acid chargers which employ a high-
voltage "anti-sulfation" routine may 'error"
during charge, or cause overcharge damage..
Standard lead-acid chargers with peak charge
voltage spec. of 14.4V or less may be used.
However, for best performance and battery
life, we recommend Shorai Battery
Management Charger #BMS01
 Fully discharge before disposal

INSTALLATION
First, remove the original lead-acid battery from
your vehicle, according to the maker's guidelines.
Compare the original battery side-by-side with
the new LFX battery. First check that the Polarity
(+/- terminals) arrangement is the same on both. If
not, contact Shorai directly for advice. Next check
that the LFX battery does not exceed the size of the
original in any dimension (length, width, height). If
the LFX is larger in any dimension, and therefore will
not fit into the stock battery box, please contact
Shorai directly.
Assuming that polarity and size are correct, now
compare the original battery to find any dimension in
which it is larger than the LFX replacement.
For example, the two may have the same width, but
the original is 25mm taller, etc. For any such
difference, apply the appropriate thickness of the
included adhesive-backed foam pieces to the
vehicle's battery box, so the LFX battery fits snugly
inside and can attach to the battery cables.
below: 5mm= 0.2")
The LFX batteries can bolt cable eyelets to either
the top or front sides of the terminals. Choose
whichever allows best cable fit. Max torque for the
terminal screws is 30kg/cm (27 inch/lb.). Do not
over-tighten. A quality anti-corrosion spray on the
terminals is recommended if used in salty and/or wet
environments.
Check that the positive terminal of the LFX
battery cannot short against any part of the vehicle;
and be sure that the original positive terminal cover,
if any, is re-installed on the LFX battery before the
battery box cover is fitted.
Shorai LFX batteries are charged to 60% of
capacity when shipped. As such it is best practice to
charge the battery before first use. Do avoid
extended cranking tests after install. Owners of
Shorai BMS01 charger systems may use the CHARGE
mode to fully top the battery, as the BMS01 will
insure ideal cell balance and perform diagnostics to
guarantee best performance. Otherwise an hour on a
proper lead acid charger before first use should be
adequate (
max charge rate should be 2A in this case)
USAGE
The most damaging two conditions for any starter
battery are prolonged storage at high temperatures,
and allowing the battery to be deeply discharged.
Compared to lead-acid batteries, LFX have less
th
than 1/4 the average self-discharge rate, and
therefore can be stored much longer without a
charge. In fact, if there is no current flow in the
system when your vehicle's key is OFF, Shorai LFX
can be stored one year or more, without damage.
Vehicles which do have a current drain while
turned off will need the battery periodically charged,
depending on the rate of current drain. If you ride at
least two hours per month year-round, that is usually
sufficient. For storage in excess of a month, the
Shorai BMS01 Battery Management System is highly
recommended, as it has a dedicated STORE mode
which monitors battery voltage levels and
automatically restores ideal voltage levels for best
battery life, while also balancing the internal cells and
