Battery Management System
for LFX™ Lithium-Iron Batteries
See http://www.shoraipower.com “Support” tab for video and
extended photo battery install guides, and FAQ for information on
charging and other topics.
LFX™ BATTERY CAUTIONS
Do not short battery terminals together!
Remove all jewelry (ring, bracelet, necklace, watch, etc.)
before working near batteries or chargers
Do not short the 5-pin BMS port
Attach ONLY Shorai Chargers to the BMS port
Do not open or allow damage to the battery case
Keep batteries away from pets and children
Do not allow LFX™ discharge below 13.0V resting
Fully discharge LFX™ battery before disposal/recycle
(connect a 12V bulb until light is out, for example)
BMS01 CHARGER CAUTIONS
BMS01 are for charging and storage of Shorai LFX™
Lithium-Iron batteries ONLY!
Connect BMS01 AC Input plug to 100V~250V 50/60Hz
single-phase AC wall socket, only.
Never allow the charger to become wet. Keep out of snow,
rain, and highly humid environments
Chargers damaged by impact, moisture, or any other cause
must NOT be used
Use the built-in retractable hook to hang BMS01 off the
floor whenever possible
Keep 5’ (1.5M) minimum clearance from flammables
around battery or vehicle during charge or store mode
Keep charge output cable connectors clean and dry. Apply
an anti-corrosion electrical grease if in salty, humid, or wet
environments
Replace charge output cables after 1200 connect cycles
BMS01 has 6V and 12V Output Ports. Only one type (12V
OR 6V) may be used at a time. Again, only ONE output port
can be cabled at any time.
BMS01 BOX CONTENTS
Shorai BMS01 with Charge & Store modes
AC input cord (US, EU, or UK version per sales location)
Battery Charge Cables for 12V
Charge Extension Cables for 12V

SETUP
Remove the BMS01 charger, AC Input cord, and the two charge
cables from the packaging, and attach the AC Input power cord to the
AC port shown below.
Note that the small 3-pin port to right of the AC Input is reserved for
factory diagnostics, and should never be used, modified, or have
anything attached to it.
The BMS01 is supplied with a long and short cable for 12V LFX™.
(cables for the 6V LFX™ batteries are sold separately). The longer
cable can be permanently attached to the battery via its 5-pin
connector (which is labeled “to battery”), and tied off at a convenient
location on the vehicle, where it is protected from water and damage.
The opposite end of the cable can be plugged directly into the BMS01
charger output port, if it is long enough to reach. If extension is
required, the shorter cable in the set can be used for that purpose. The
12V/6V charge ports are shown below.
At this point you should have the battery charge cable connected to
the battery BMS port, and the AC input cord connected to the charger.
Now insert the AC plug into an appropriate AC wall socket.
Whenever possible, use the charger’s retractable hook to hang the
BMS01 above the floor, in a location which allows easy access to the
battery charge cable. Now plug the battery charge cable into the
correct LFX™ charge output port (or into the extension cable).
The charger will “beep” a few times when the LFX™ battery is
connected to the charge cable, and you should see both the yellow
Store and green Charge LED on solid, indicating that the charger is
ready for input. After pressing either the store or charge button you
will hear a “triple” beep which indicates the charger is active. Note-
If a button is not pressed within 30 seconds the charger will power
down. To turn the BMS01 on, press the charge button.
The photo above shows the two operation buttons, and their
corresponding LED indicators.
Store Mode - The BMS01 Store Mode is optimized to maintain
Shorai LFX™ batteries for best lifespan and performance. Once
Store Mode has been started, the BMS01 can remain attached to the
LFX™ battery and wall power indefinitely, until the vehicle is to be
used again. When Store Mode is activated, the BMS01 will either
charge or discharge the LFX™ battery until an approximate 80%
charged state is reached. At that point the BMS01 will monitor
capacity, and when ~60% state is reached will re-charge to ~80%
level, and so on. This range is ideal for lithium-iron storage. LFX™
crank vehicles strongly even if well below 60% capacity state,
however for the best performance and longest life span press the
charge button to fully charge the battery before use.
Charge Mode - The BMS01 charge mode charges at 2A peak rate,
while balancing the internal LFX™ cells and performing battery
diagnostics. Charge completion will typically occur within 30 minutes
to 4 hours, depending on the size and state of the battery at charge
start. When the battery voltage reaches ~14.4V the charging process is
complete and the BMS01 unit will beep several times, the light will
turn solid green, and then power off within 30 seconds. Important-
after charging is complete disconnect the charger from the battery to
help maintain a high state of charge.

Flashing Together
1 When the AC power cord is first plugged to AC power, each LED
will turn on solid, to indicate charger READY for input. Note- If a
button is not pressed within 30 seconds the charger will power down.
2When the LFX™ battery is above 50% capacity at the START of
CHARGING, only the Green LED will flash. However, if the LFX™
is below 50% capacity at the start of charging, the yellow and green
LED will flash alternately. This warns you that the battery has been
allowed to drop low in voltage, and that you may need to charge more
often, or use the Store Mode while parked long term. To correct this
condition press the charge button, a “triple”beep indicates the charger
is active and the lights continue to alternate. Once the battery reaches
50% + capacity the charger returns to flashing green only.
3 Errors are indicated by a flash/pause sequence of both LED together
(Contact Shorai). An alarm buzzer may also sound until error is
corrected or power off:
1 flash/pause = Internal input voltage error. Check that AC
power is in range and properly connected. Try another outlet.
2 flashes/pause = Polarity error. Not typical.
3 flashes/pause = Open Circuit. Charge cables not properly
connected, broken, or worn. Inspect and/or try new cable set.
4 flashes/pause = Battery/Cell voltage error. Cell variation
issue, use the store mode for 24hrs, then charge to correct issue.
