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 of14.8V
(7.4V for 6V types)
•
Lead-acid chargers which employ a highvoltage
„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

Shorai Battery Management Charger #BMS01.
Regular Lead-Acid
charger/tenders CAN be used, HOWEVER, you may
NOT use a charger/tender if it has an automatic
„DESULFATION MODE", which CANNOT be turned
off.

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 Cheb 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
be used. However,
battery chargers
(13.6 - 14.4V
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.
5mm= 0.2")
The LFX batteries can bolt cable eyelets to ether the top or
front sides of the terminals. Choose whichever allows best
for 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
or
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
at
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 (
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 than 1/4
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
