ANever attempt to charge or discharge the following types of batteries:
• A battery tted with an integral charge circuit or a protection circuit
• A battery pack which consists of dierent types of cells (including
dierent manufacturer’s cells)
• A battery that is already fully charged or just slightly discharged and
non-rechargeable batteries (these pose an explosion hazard)
• A faulty or damaged battery
• Batteries installed in a device or which are electrically linked to other
components
• Batteries that are not expressly stated by the manufacturer to be
suitable for the currents the charger delivers during the charge process
PLEASE BEAR IN MIND THE FOLLOWING POINTS BEFORE YOU
COMMENCE CHARGING:
• Did you select the appropriate program suitable for the type of battery you
are charging?
• Did you set up the adequate current for charging or discharging?
• Have you checked the battery voltage? Lithium battery packs can be wired
in parallel and in series, i.e. a 2-cell pack can be 3.7V (in parallel) or 7.4V (in
series).
• Have you checked that all connections are rm and secure?
• Make sure there are no intermittent contacts at any point in the circuit.

Standard Battery Parameters
WHEN ADJUSTING YOUR X2 AC PRO CHARGING PARAMETERS, BE SURE
YOU SELECT THE PROPER BATTERY TYPE AND CELL VOLTAGE FOR THE TYPE
OF CELL YOU ARE CHARGING. CHARGING BATTERIES WITH THE WRONG
SETTINGS MAY CAUSE THE CELLS TO BURST, CATCH FIRE OR EXPLODE.
Charging
Before charging your batteries, it is critical that you determine the maximum
allowable charge rate for your batteries. The X2 AC Pro is capable of charging
at high rates that may not be suitable or safe for your particular batteries. For
example, Lithium cells are typically safe to charge at 1C, or the total mAh÷1000.
A 1200mAh battery would have a 1C charge rate of 1.2 amps. A 4200mAh
battery would have a 1C charge rate of 4.2 amps. Some manufacturers are
oering Lithium cells that can be charged at greater than 1C but this should
ALWAYS be veried before charging a Lithium battery at rates higher than 1C.
Voltage is just as critical as the charging amperage rate and this is determined
by the number of cells in series, or “S”. For example, a 3S LiPo is rated at 11.1 volts
(“S”multiplied by a single LiPo cell with a nominal voltage of 3.7 volts DC. 3 cells
x 3.7 volts each equals 11.1 volts DC).
Connect the battery’s main leads to the charger output: red is positive and
black is negative. Keep in mind that the gauge or thickness of your charging
leads from the X2 AC Pro to your battery must be of an acceptable current
rating to handle the applied charge current. For maximum safety and charging
eectiveness, always match or exceed the main battery lead rating when
assembling or selecting your charging leads. If you charge a battery at a high
current rate (amperage) with a charging lead not rated for the chosen amperage,
the wire could get hot, catch re, short out and/or potentially destroy your
battery and the charger.
Warning
Warning and Safety Notes [cont.]

7
When in doubt, always use a higher gauge wire (lower AWG number). It is
common to see charging leads constructed of 14AWG, 16AWG or 18AWG wire.
Always refer to recommendations from your battery manufacturer for your
specic battery type and size before initiating a charge or discharge process.
Do not attempt to disassemble or modify Lithium or Lead-Acid battery packs.
Discharging
The X2 AC Pro discharging functions are for two specic purposes:
• Refreshing the capacity of a Nickel-based battery that has lost capacity over
time (NiMH or NiCd).
• Reducing the voltage of a Lithium battery for safe storage.
LITHIUM CHEMISTRY BATTERY PACKS SHOULD ONLY BE DISCHARGED
TO THEIR MINIMUM SAFE VOLTAGE, NO LOWER. DEEP DISCHARGING
A LITHIUM CELL WILL DO PERMANENT DAMAGE. REFER TO THE
STANDARD BATTERY PARAMETERS TABLE ON PAGE 6 OF THIS MANUAL
FOR MINIMUM DISCHARGE VOLTAGES.
LiPo & LiHV Charge/Discharge Cycling
Lithium batteries are known to reach full capacity after a break-in period of
about 10 charge/discharge cycles. We do not recommend you use the X2 AC
Pro charger to do this; normal use and recharging will achieve the same results.
If you wish to perform a Lithium break-in on the bench with the X2 AC Pro,
discharging to minimum acceptable voltages and performing a balance charge
at 1C maximum rate is recommended. If you choose to break in your Lithium
batteries under normal use, charging at only 1C for the rst ten cycles will help
ensure full performance and service life from your Lithium cells.

1 to 5 cycles of charge > discharge or discharge > charge sessions for optimal
battery performance and balancing.
Soldering Iron:
The X2 AC Pro has a built-in 60-watt soldering iron for the times when
something must be repaired at the track or eld.
Automatic Charging Current Limit:
You can set the upper limit of the charging current when charging your NiMH
or NiCd battery. The ‘AUTO’ charging mode, however, is recommended when
charging NiMH batteries with low impedance and capacity.
LiPo Battery Meter:
The user can check the battery’s total voltage, the highest voltage, the lowest
voltage and the voltage of each cell.
Battery Internal Resistance Meter:
The user can check the battery’s total internal resistance and the internal
resistance of each cell.
Capacity Limit:
The charging capacity is always calculated as the charging current multiplied by
time. If the charging capacity exceeds the limit, the process will automatically
terminate according to the maximum value previously set.
Temperature Threshold*:
The battery’s internal chemical reaction will cause the temperature of the
battery to rise. If the temperature limit is reached, the process will be terminated.
* This function is available by connecting an optional temperature probe which is available as
a separate purchase.
Processing Time Limit:
Protect your battery by setting a maximum time limit for charging and discharging.

CHARGE The charger will charge NiMH and NiCd batteries using the charger current set by
the user.
AUTO CHG
In this program, the charger detects the condition of the batteries which is connected to
the output and automatically charges the batteries.
Note: You should set up the upper limit of the charge current to avoid damage by
excessive feeding current. Some batteries of low resistance and capacity can lead
to higher current.
DISCHARGE This mode is for discharging NiMH/NiCd batteries.
RE-PEAK
In re-peak charge mode, the charger can peak charge the battery once, twice or three
times in a row automatically. This is good for conrming the battery is fully charged and
for checking how well the battery receives fast charges.
CYCLE 1 to 5 cyclic and continuous process of charge > discharge or discharge > charge is
operable for battery refreshing and balancing to stimulate the battery’s activity.
Pb CHARGE This mode is for charging Pb batteries.
DISCHARGE This mode is for discharging Pb batteries.

Lithium Battery Program [LiP0/LiHV/LiFe/Lilon]
Lithium:
This program is only suitable for charging/discharging Lithium chemistry
batteries (LiPo, LiHV, LiIon and LiFe). The X2 AC Pro oers the following Lithium
charge modes: Charge, Balance Charge, Fast Charge, Storage and Discharge.
BEFORE SELECTING A CHARGE MODE, IT IS CRITICAL THAT YOU SELECTTHE
CORRECT TYPE OF LITHIUM BATTERY TO BE CHARGED. FAILURE TO DO SO
CAN RESULT IN DAMAGE TO THE BATTERY AND POSSIBLE EXPLOSION.
Selecting a Lithium Battery Type:
From the “BATT/PROGRAM” screen, press the INC. ▬
or DEC +button to scroll through the battery type
selections. Once you have selected the correct battery type, press the ENTER/
Start ►button to enter the charge/discharge menu.

BEFORE YOU BEGIN CHARGING YOUR BATTERY, MAKE SURE YOU
HAVE READ AND UNDERSTAND ALL OF THE WARNINGS AND SAFETY
INFORMATION CONTAINED ON PAGES 0207.
IN THE CHARGE MODE, LITHIUM BATTERIES CAN BE CHARGED WITHOUT
THE USE OF A BALANCE ADAPTOR. A BALANCE ADAPTOR CAN BE USED,
BUT IT IS NOT REQUIRED. BALANCE CHARGE MODE IS RECOMMENDED
FOR ANY BATTERY WITH A BALANCE LEAD.
See page 12 for the appropriate charging connections setup for this operation.
First, select the correct battery type by following the instructions on page 16.
Once you have set the correct battery type, press the ►button once to enter
the charge mode and battery settings screen, use the INC. ▬or DEC +to select
a “CHARGE”mode. Press the ► button again and the amperage value will begin
ashing. Use the +or ▬ buttons to adjust the value to the desired charge rate.
Follow the instructions provided with your battery when setting the charge
amperage rate.
Press the ►button again and the voltage value will begin
ashing. Use the +or ▬buttons to adjust the value to
the desired rate. The voltage and cell count should match the values listed on

You are now ready to begin charging. Press and hold the
ENTER/Start ►button until you see “BATTERY CHECK,”
followed by the “CONFIRM (ENTER) / CANCEL(STOP)“
screen. The “CONFIRM/CANCEL“ screen displays the
number of cells detected by the processor as ”R”and the number of cells you set
as “S”. If both numbers are identical, you may press and hold the ENTER/Start ►
button to conrm and begin charging. If these numbers do not match, press the
BATT/PROG Stop ■ button to return to the previous screen and carefully check
the number of cells of the battery pack before proceeding.
DURING CHARGING/DISCHARGING, THE BATTERY SHOULD BE PLACED
INSIDE A FIRE PROOF/RETARDANT BAG AND ON A FIRE PROOF SURFACE
AWAY FROM OTHER COMBUSTIBLE OBJECTS.
Once charging has commenced, the charger will display
the following real-time information: battery type/cell
count, charging current, battery voltage, charging time and charged capacity.
If you are using a balance adaptor during charging, you
may press the +button to view the voltage of each
individual cell. You can also view a variety of other information as detailed later
in this manual. Once the battery is fully charged, the screen will read “FINISHED”
and the charger will emit a chiming sound. Press the ■button to return to the
setup screen. You may also press the ■button at any time during the charging
process to stop charging.
Lithium Balance Charge Mode:
This function is for balancing the voltage of individual Lithium-polymer battery
cells while charging. In order to use the Balance Mode, the battery must have a
balance lead. Charging in this mode is dierent from the normal modes because
the built-in processor monitors the voltage of each individual cell and controls
the discharge of each individual cell in order to equalize the voltage. Use of
a balance adaptor with any battery that has a balance lead will improve the
performance and lifespan of your battery.
BEFORE YOU BEGIN CHARGING YOUR BATTERY, MAKE SURE YOU
HAVE READ AND UNDERSTAND ALL OF THE WARNINGS AND SAFETY
INFORMATION CONTAINED ON PAGES 0207.
