SPECIAL FEATURES
Optimized operating software
The X1 "auto" feature sets the charge and discharge current for you
automatically, preventing overcharging which can damage your
battery. In the event of an error, the X1 instantly disconnects the
circuit and sounds an alarm once. This feature can be set by the
user and controlled through the two-way link for maximum safety
and minimizes these type of problems.
SPECIAL FEATURES
Internal independent lithium battery balancer
The X1 features a built-in a cell voltage balancer so you don’t
need to fuss with external balancers while charging.
Balancing individual cells during discharging
The X1 also monitors and balances each cell in the pack
individually while discharging. If the voltage of any single cell is
abnormal, the X1 will display an error message and the process
will end automatically.
Adaptable to various types of lithium batteries
The X1 will charge and discharge a variety of Lithium batteries,
such as Li-ion, LiPo and the new LiFe series of batteries.
Fast and storage mode of lithium batteries
The X1 features two styles of charging. "Fast" charge reduces the
charge duration while "Store" controls the final voltage of your
battery, to optimize your packs for long term storage and maximum
lifespan.
Maximum safety
Our delta-peak voltage detection program ends the charge cycle
whenever a battery's voltage exceeds the set threshold.

- 04 -
SPECIAL FEATURES
Automatic charging current limit
Charging current can set by the user when charging NiCd or
NiMH batteries. The 'AUTO' charging mode, however, is
recommended when charging NiMH batteries with low
impedance and capacity.
Capacity and Temperature Limits
The charge process will terminate if either the charging capacity
or battery temperature exceeds the limit set by the user.
Temperature function requires an optional temperature probe,
which is not included with the X1.
Processing time limit
Protect your battery by setting a maximum time limit for charging
and discharging.
Input power monitoring
The X1's input voltage is monitored to protect the battery from
becoming damaged. The process ends automatically if it drops below
the limit.
Data store/load
A maximum of five setting profiles can be stored for your
convenience. The X1 will store the data pertaining to a program's
settings and you can call up data at anytime.
Cyclic charging/discharging
A battery can be cycled 1 to 5 times. This process is good for
refreshing and balancing your battery.

WARNING AND SAFETY NOTES
To avoid a short circuit between the charge leads, always
connect the charge cable to the charger first, then connect the
battery. Reverse the sequence when disconnecting.
Do not connect more than one battery pack to this charger at
any one time.
Never attempt to charge or discharge the following types of
batteries:
A battery pack which consists of different types of cells
(including different manufacturers).
Batteries that are not expressly stated by the manufacturer to
be suitable for the currents the charger carries during the
charge process.
Batteries installed in a device or those which are electrically
linked to other components.
A battery fitted with an integral charge circuit or a protection
circuit.
A faulty or damaged battery.
Batteries that require a different charge technique from NiCd,
NiMh, LiPo or a Gel cell (Pb, Lead acid).
Non-rechargeable batteries (may pose an explosion hazard).
A battery that is already fully charged or just slightly discharged.
Please bear in mind the following points before commencing
charging:
Did you select the appropriate program suitable for the type of
battery you are charging?
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).
Did you set up adequate current for charging or discharging?

- 09 -
WARNING AND SAFETY NOTES
Have you checked that all connections are firm and secure?
Make sure there are no intermittent contacts at any point in the
circuit.
Charging
During the charging process, a specific quantity of electrical
energy is fed into the battery. The charge quantity is calculated
by multiplying charge current by charge time. The maximum
permissible charge current varies depending on the battery type
or its performance, and can be found in the information provided
by the battery manufacturer. Only batteries that are expressly
stated to be capable of quick-charge are allowed to be charged
at rates higher than the standard charge current.
Connect the battery to the terminal of the charger: red is positive
and black is negative. Due to the resistance difference between
the cable and the connector, the charger can not detect the
resistance of the battery pack. In order for the charger to work
properly, the charge leads should be of adequate cross-section
with high quality (normally gold-plated) connectors fitted to
both ends.
Always refer to the manual provided by the battery manufacturer
pertaining to charging methods, recommended charging current
and charging time. Lithium batteries, in particular,should be
charged strictly according to the charging instructions provided
by the manufacturer.
Special attention should be paid to the connection of the Lithium
battery.
Do not attempt to disassemble the battery pack arbitrarily.

- 10 -
WARNING AND SAFETY NOTES
Please note that Lithium battery packs can be wired in parallel
and in series. In the parallel connection, the battery’s capacity is
calculated by multiplying the single battery’s capacity by the
number of cells with total voltage remaining the same. The
voltage’s imbalance may cause a fire or explosion. A Lithium
battery is recommended to charge in series.
Discharging
The main purpose of discharging is to clean the residual capacity
of the battery, or to reduce the battery voltage to a defined level.
The same attention should be paid to the discharging process as
charging. The final discharge voltage should be set up correctly
to avoid deep-discharging. A Lithium battery can not be discharged
to lower than the minimum voltage, or it will cause a rapid loss of
capacity or a total failure. Generally, a Lithium battery doesn’t need
to be discharged. Please pay attention to the minimum voltage of
a Lithium battery to protect the battery.
Some rechargeable batteries have a memory effect. If they are
partly used and recharged before the whole charge is
accomplished, they remember this and will only use that part of
their capacity next time. It is said that NiCd and NiMH batteries
suffer from this memory effect and NiCd has more memory effect
than NiMH.
Lithium batteries are recommended to be discharged partially
rather than fully discharged. Frequent full discharging should be
avoided if possible. Instead, charge the battery more often or use
a battery of larger capacity.Full capacity cannot be used until it
has been subjected to 10 or more charge cycles. The cyclic
process of charge and discharge will optimize the capacity of
the battery pack.

INITIAL PARAMETER SET-UP (USER’S)
INITIAL PARAMETER SET-UP (USER’S SET-UP)
As a default, this charger will be set to default user settings when it is
connected to AC 110-240V or DC 11-18V for the first time. The screen
displays the following information in sequence and the user can
change the parameters on each screen.
The X1 recognizes the cell count of the Lithium
battery automatically at the beginning of the charge
or discharge process to avoid an erroneous setting
by the user. To prevent a deeply discharged battery,
which can be perceived incorrectly, from causing an
error, you can set the timer to verify the cell count
by the processor. Normally, 10 minutes is enough
to perceive the cell count correctly. For a battery of
larger capacity, you may extend the time term.
However, if you set the it too long for a battery of
smaller capacity, the charge or discharge process
can be finished within the time term with an
erroneous cell count. This may cause a fatal result.

batteries: LiFe(3.3V), Lilo(3.6V) or LiPo(3.7V).
This is very important so you have to check the
battery carefully and set it up correctly. If it is
different from the correct setting, the battery
may explode during charge process.
If you need to alter the setting in the program, press the “Start/Enter”
key to make it blink then change the setting with the “INC” or “DEC”

recognizes the cell count incorrectly at the
beginning of the charge or discharge process,
you may extend the time. Otherwise, you should
use the default value.
This shows the cutoff voltage for the automatic
charge termination of a NiMH and NiCd battery.
The effective setting ranges from 5 to 20mV per
cell. If the trigger voltage is set higher, there is a
danger of overcharging the battery; if it is set
lower, there is a possibility of premature
termination. Please refer to the technical
specification of the battery.
(NiCd default: 12mV, NiMH default: 7mV)
The temperature cutoff will be turned on or off
with the use of the optional temperature probe
by contacting the surface of the battery. If it is
on, set the maximum temperature at which the
charger should allow the battery to reach during
charging. Once a battery reaches this
temperature, the process will be terminated to
protect the battery.
Waste time
CHG/DCHG 5min
The battery becomes warm after cycles of the
charge/discharge process. The program will
insert a time delay after each charge/discharge
process to allow the battery enough time to cool
down before beginning the next cycle of charge/
discharge. The setting ranges from 0 to 60 minutes

When the charge process starts, the integrated
safety timer starts to run simultaneously. If an
error occurs or the termination circuit cannot
detect whether the battery is fully charged or not,
the unit is programmed to prevent overcharging
and will terminate the charge process. Please refer
to the statement below to calculate the timer you set.
Safety Timer Calculation
When charging NiCd or NiMH batteries, divide the capacity by the
current, then divide the result by 11.9. Set this number of minutes as
the setting for the safety timer setting. If the charger stops at this time
threshold, about 140% of the capacity will have been fed into the battery.
For example:
Capacity Current Safety Time
2000mAh 2.0A (2000/2.0=1000)/11.9=84 minutes
3300mAh 3.0A (3300/3.0=1100)/11.9=92 minutes

This program provides a maximum capacity
protection function. If the Delta-peak voltage
can not be detected or the safety timer times
out, the charge process will stop automatically
when the battery reaches the user-set maximum
charge capacity,
A beep sounds to confirm the user's operation
every time a button is pressed. The buzzer or
melody sounds at various times during an
operation to confirm a different mode change.
These functions can be switched on or off.
This function monitors the voltage of the input
source used to power the charger. If the voltage
is lower than the user setting, the program will
end forcibly to protect the input source.

This function is for balancing the voltage of Lithium-polymer battery cells
individually while charging. In the balance mode, the battery needs to
have a balance lead to connect to the balance port at the right side of
the charger and the battery's power leads to the output of the charger.
Charging in this mode is different from the normal modes because the
built-in processor monitors the voltage of each individual cell and controls
the input current fed into each cell in order to equalize the voltage.
