1. Before attempting to charge
or discharge a battery, first
read the safety warnings
and charging instructions
provided with your battery.
Make sure to contact the
battery manufacturer if
these instructions were not
provided or are unclear.
2. Before charging or discharging
any battery, carefully inspect
the pack to ensure no physical
damage, swelling or “ballooning”
is evident. Signs such as this
indicate that a dangerous
problem exists with the
battery that could lead
to a catastrophic failure
including fire and explosion.
3. Under no circumstances should
you charge or discharge any
battery that has become
swollen “ballooned” or been
damaged in any way. Refer to
the safety warnings provided
with your battery for further
instruction.
4. Batteries on charge, or
discharge MUST remain
under constant observation
so that you may react quickly
should any problems arise.
5. Always keep a class D chemical
fire extinguisher
6. Be sure to understand the
specifications of the battery pack
to be charged or discharged. If
the charger program is set up
incorrectly the battery pack can
be severely damaged, catch
fire, and cause personal injury.
Refer to the battery label for the
specifications of your battery
pack, and if they are
unclear be sure to contact the
manufacturer.
7. Battery packs when improperly
charged or discharged, can
sustain permanent damage,
catch fire, explode, and cause
personal injury.
8. Immediately discontinue the
charging or discharging of a
LiPo battery that begins to swell
or “balloon”.

9. This charger and the battery to
be charged or discharged should
be placed upon a heat-resis-
tant, non-flammable and non-
conductive surface away from
any flammable materials.
10. Never charge a battery pack
that feels too hot to the touch.
Always allow a battery to cool to
ambient temperature before
charging.
11. Always make sure to use a LiPo
safety sack or other fireproof
containers when charging or
discharging battery packs.
12. Charge each battery pack
individually. Never charge
battery packs in series or par-
allel. Using this method may
result in the improper cell
recognition of the charger,
improper charging rate, and over
charging that may lead to fire or
explosion.
13. Never leave the battery charger
unsupervised when it is con-
nected to its power supply.
If any type of malfunction
is observed immediately
terminate the charging
process and refer to the operation
manual.
14. Keep the ac balance charger/
discharger away from dust,
water, heat, direct sunlight and
vibration.
15. Do not disassemble, modify, or
attempt any form of repair on
this charger.

Lithium Batteries
To charge a LiPo/LiHV/LiFe/Li-ion
battery, press the BATT TYPE/STOP
button until the screen shows Lithium
Battery Mode and then press START/
ENTER.
The screen is broken up into four
quadrants and the value in each
quadrant is adjustable allowing the
charger to be configured to a wide
range of lithium batteries. Before
proceeding, be sure to confirm the
appropriate settings for your bat-
tery as recommended by the battery
manufacturer.
To change the first quadrant’s value
press the START/ENTER button and
the value will begin to flash. Change
the value using the INC (increase) or
DEC (decrease) buttons. Pressing
the START/ENTER button once more
will cause the next quadrant value to
flash and this can be changed in the
same way. When the final selection
for quadrant 4 has been made press
the START/ENTER button once more.
At this point no value should be flash-
ing and this information has been
saved. Unless these settings are later
adjusted, the next time the charger is
used these settings will automatically
be recalled with the default mode
being charge.

Warning: Lithium battery packs
when improperly charged or
storage charged, can sustain
permanent damage, catch fire,
explore, cause personal injury
and property damage.
Warning: Never charge on or

Quadrant 1 allows the charger to be
set for LiPo, LiHV, LiFe, and Li-ion
battery types. By default the charger
is set to LiPo mode supporting 7.4V,
11.1V, and 14.8V batteries. Notice the
nominal battery voltage in quadrant
4 will change to match the selected
lithium battery type.
Quadrant 2 allows the charger to
be set for charge or storage. Charge
mode provides the lithium battery with
a balancing charge, which ensures the
cell voltages are equalized throughout
the charge process. Storage mode
will either balance charge or discharge
the battery as required to return the
battery to a safe storage voltage,
which is roughly nominal voltage of the
battery pack.
Note: Storage mode should be
used for all lithium batteries within 24
hours of having depleted the battery
or within a few days for a charged
battery pack that will not be used for a
week or more. This will help to prevent
irreversible damage to your lithium
battery.
Quadrant 3 allows the charge or
storage charge rate (current in amps)
to be set. Confirm the recommended
charge rate for your battery and set this
per the manufacturer’s recommenda-
tions. As a general reference, a safe
charge rate for LiPo batteries is 1C or 1
times the capacity of the battery in amp

Confirm the nominal voltage of your
battery pack, which is typically
listed on the battery label. If the label is
damaged or this informaiton is unclear
contact the battery manufacturer
before proceeding.
After having confirmed all values are
accurate, to start the LiPo/LiHV/
LiFe/Li-ion charge or storage charge,
first connect the batteries main lead
(largest two red and black wires with
a single plug) to the charger. This
charger has a built in XT60 charge
lead port and also includes a XT60
(yellow) to EC3 (blue) adapter. Contact
your local hobby shop for additional
adapters as needed.
With the main lead connected to the
charger, now connect the battery
balance lead (smallest wires with a
single plug) to the appropriate balance
lead port location, which is just to the
left of the XT60 charge lead port.
