Standard Battery Parameters
WHEN ADJUSTING YOUR X2 AC PLUS CHARGING PARAMETERS, BE SURE
YOU SELECTTHE PROPER BATTERYTYPE AND CELLVOLTAGE FOR THETYPE
OF CELL YOU ARE CHARGING. CHARGING BATTERIES WITH THE WRONG
SETTINGS MAY CAUSETHE 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 Plus 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 Plus 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
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 Plus 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
Plus 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 Plus,
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.

Re-Peak Mode of NiMH/NiCd Battery:
In re-peak charge mode, the charger can peak charge the battery once, twice,
or three times in a row automatically. This function is useful for ensuring a full
battery charge.
Delta-Peak Sensitivity for NiMH/NiCd:
This automatic charge termination program is based on the principle of the
Delta-peak voltage detection. When the battery’s voltage exceeds the threshold,
the process will be terminated automatically.
Cyclic Charging/Discharging:
1 to 5 cyclic and continuous charge > discharge or discharge > charge sessions
are optimal for battery performance and balancing.
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.

Powered by AC Household Current: In AC mode the X2AC+ has a maximum
charging output of 100 watts total. This charge output can be allocated
dierently to each channel utilizing the Power Distribution feature.
To adjust the wattage between channel got to BATT/PROGRAM menu and use
the INC. – or DEC + buttons to get to the SYSTEM SETTINGS, press ENTER/Start
to enter the System settings menu and use the – or + buttons to scroll to the AC
Max Power Set screen. Press ENTER/Start and the wattage amount will begin to
blink. Use the – or + buttons to adjust the wattage for that channel.
Adjusting one channel will change the other channel proportionally. i.e
you change one channel to 70 watts the other channel will only have 30
watts available for charging.
Powered by Automotive Battery or DC Power Supply: In DC mode the X2AC+
has a maximum charging output of 200 watts total. This is allocated a 100 watts
per channel and cannot be adjusted. It is extremely important that you use
either a fully charged 13.8V car battery or a high quality AC/DC power supply
in the range of 11-18V DC output with minimum power of 240W or higher to
ensure a reliable performance.

Program Description
This charging mode is for charging LiPo/LiFe/LiIon/LiHV battery in normal mode.
This program is for charging or discharging
will not be used for long time.
The charging capacity may be less than normal charging but the
process time will be reduced.
This mode is for balancing the voltage of lithium-polymer battery
cells while charging.
The charger will charge NiMH and NiCd batteries using the
charge current set by the user.
In this program the charger detects the condition of the battery
which is connected to the output and automatically charges the
battery.
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 confirming the battery is fully charged, and for checking
how well the battery receives fast charges.
1 to 5 cyclic and continuous process of charge>discharge or
