Standard Battery Parameters
WHEN ADJUSTING YOUR X1 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 X2-700 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 X1 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
Warning

7
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. 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 X2-700 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 X2-700
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 X2-700
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.

Features
Optimized Operating Software
The X2-700 “auto” feature sets the charge and discharge current for you au-
tomatically, preventing overcharging which can damage your battery. In the
event of an error, the X2-700 instantly disconnects the circuit and sounds an
alarm. This feature can be set by the user and controlled through the two-way
link for maximum safety.
Data Store/Load
A maximum of ve setting proles can be stored for your convenience. The
X2-700 will store the data pertaining to a program’s settings and you can recall
data at any time.
Internal Independent Lithium Battery Balancer
The X2-700 features a built-in cell voltage balancer so you don’t need to fuss
with external balancers while charging.
Balancing Individual Cells During Discharging
When used with a balancing board the X2-700 can monitor and balance each
cell in the pack individually while discharging. If the voltage of any single cell
is abnormal, the X2-700 will display an error message and the process will end
automatically.
Adaptable to Various Types of Lithium Batteries
The X2-700 will charge and discharge a variety of Lithium batteries such as Li-
ion, LiPo, LiFe and the new higher voltage LiPo, (LiHV) batteries.
Multiple Lithium Battery Charge Modes
The X2-700 features four methods of charging: Regular charge, Fast charge, Bal-
ance charge and Storage charge modes. We highly recommend using balance
charge as it is the safest and best way to charge lithium chemistry batteries. If
you plan on not using your Lithium chemistry batteries for an extended period
of time, Storage charge mode is recommended to optimize your packs for long
term storage and maximum lifespan.
Syncronous Mode
When charging two identical batteries, both channels can be set using channel
one.

11
Features
Input Power Monitoring
The X2-700’s input voltage is monitored to protect the battery from becoming
damaged. The process ends automatically if it drops below the limit.
Capacity and Temperature Limits
The charge process will terminate if either the charging capacity or battery
temperature exceeds the limit set by the user. The temperature function
requires an optional temperature probe, which is not included with the X2-700.
Processing Time Limit
Protect your battery by setting a maximum time limit for charging and
discharging.
Cyclic Charging/Discharging
A battery can be cycled 1 to 5 times consecutively. This process is good for
refreshing and balancing your battery.
Maximum Safety
Our delta-peak voltage detection program ends the charge cycle whenever a
battery’s voltage exceeds the set threshold.
Automatic Charging Current Limit
Charging current can be set by the user when charging lithium NiCd or NiMH
batteries. 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 and lowest as well as
each cells voltage.
Battery Internal Resistant Meter
The user can check the internal resistance of each cell of the battery.
PC Control Using Charge Master Software
The free Charge Master software gives you unparralled ability to operate the
charger through the computer. You can monitor pack voltage, cell voltage and
other data during the operation. Additionally, you have the ability to set up the
charger and update the rmware.

Lithium Battery Operations (cont.)
Lithium
Charge: Basic charge mode used for normal charging
Discharge: Basic discharge mode used for normal discharging
Storage: This mode is for charging or discharging batteries to the optimal stor-
age voltage for the purpose of storing the batteries for a longer period of time.
Fast Charge: Charges faster than regular“Charge” mode although capacity
may be reduced resulting in shorter run times.
Balance Charge: For batteries with a balancing connection, this mode balanc-
es the voltage of each individual cell while charging. This is the safest and most
optimal way to charge Lithium chemistry batteries.
Micro Charge: Charges at a rate from 10~500mAh for smaller batteries
Micro Storage: Charges or discharges at a rate from 10~500mAh
Fast Charge: Charges faster than regular“Charge” mode although capacity will
be slightly reduced.
Setting the Charge/Discharge Current: Once you nd the mode you
wish to use press the ENTER/START button and the current value will begin
ashing. Use the < DEC. or INC. >buttons to Set
the Charge/Discharge current based on the battery
manuafcturer’s recomendations. Once you have set the
Charge/Discharge current, press ENTER/START to move to the battery voltage
setting.
Most manufacturers suggest a 1C charge rate for lithium chemis-
try batteries although some manufacturers are oering Lithium
cells that can be charged at a rate greater than 1C. This should
ALWAYS be veried before charging a Lithium battery at rates
higher than 1C.
Setting the Voltage: The cell count indicator will be ashing, use the < DEC.
or INC. >buttons to adjust the value to the desired
number. Press ENTER to conrm. The voltage and cell
count should match the values listed on the battery label.

Pb (Lead-Acid) Battery Operations
Lithium
Pb (Lead-Acid)
This program is only suitable for charging Pb (lead-acid) batteries with nominal
voltages of 2 to 24V. A Pb (lead-acid) battery is signicantly dierent from
NiCd/NiMH batteries. Pb batteries can only deliver current lower in comparison
to their capacity. The same restriction applies to the charging process.
Consequently, the optimum charge current can only be 1/10 of the capacity.
A Pb battery cannot be used for fast charging. Please follow the instructions
provided by the battery manufacturer.
The X2-700 oers the following Pb charge modes: Charge and Discharge.
