Congratulations on your purchase of the Hitec X2-400 Multi-Charger. You are now the
owner of a compact multi chemistry battery charger with battery management and integral
Lithium battery balancing features. The X2-400 features four totally independent and
identical 50 watt charging circuits for a total power of 200 watts. As a result, it can simulta-
neously charge or discharge up to 4 separate battery packs.
The X2-400 can be attached to a 12 volt car battery with the include connector you
connect it to a 12 – 18 V DC power supply with a minimum amperage rating of 60 amps.
The Hitec X2-400 is simple to use, but the operation of a sophisticated automatic charger
such as the X2-400 does require some knowledge and education by the user. This
instruction manual is designed to ensure that you can quickly become familiar with the
charger’s functions and capabilities. It is important that you read this instruction manual in

INTRODUCTION
Specifications
The Hitec X2-400 allows you to charge up to two different batteries simultaneously. The
charger will automatically charge all 4 batteries at a time to their maximum capacity. Addi-
tionally the batteries being charged do not need to have the same configuration or the
same chemistry. Therefore you can connect any one of a NiMH/NiCD/LiPo/LiFe battery
into any of the charging ports. This eliminates the time consuming efforts of charging all
your batteries separately.

Optimized Operating Software
The software in X2-400 automatically controls the current rate during the charging or
discharging process. This feature can prevent the user from overcharging their batteries
which could lead to damage or injury. If the charger detects a malfunction, the circuit
automatically disconnects and an alarm will sound, The operating functions of the
X2-400 are controlled through a two-way communication link in order to maintain
maximum safety with minimal errors. All of these functions and settings are easily config-
ured by the user.
Internal Independent Lithium Battery Balancers
Each channel of the X2-400 employs an individual-cell voltage balancer eliminating the
need for an external balancer for balance charging.
Monitors Individual Cells During Battery Discharging
During the process of discharging, the X2-400 can monitor and display each cell of
lithium type batteries individually. If the voltage of any single cell is abnormal, an error
message will display and the discharge process will automatically end.
Charges Most Popular Lithium Batteries
The X2-400 is compatible with the three most common Lithium chemistry batteries,
Li-Ion, LiPo and LiFe.
Multiple Lithium Battery Charge Modes
The X2-400’s programming allows for Fast Charge, Balance Charge or Storage Charge
Modes for LiPo, Li-Ion, and LiFe batteries.
)DVW&KDUJH0RGH Reduces charging time, but does not balance the cells, this
mode only charges the battery to approximately 90% capacity.
%DODQFH&KDUJH0RGH Monitors individual cell voltage, keeping the cells within an
acceptable voltage range and charges the pack to peak capacity.
6WRUDJH&KDUJH0RGH Used for long-term battery storage. Adjusts the voltage
level so the battery will not be damaged during long term storage.
Delta Peak Technology for Maximum Safety
The automatic charge termination program utilizes Delta-Peak voltage detection.
When the battery's voltage exceeds the threshold, the charge process is terminated
automatically.
Automatic Charging Current Limit
The maximum charge rate can be manually set when charging NiCd or NiMH batteries.
The X2-400 will auto-detect when the batteries are fully charged and shut off, even with
low impedance NiMH packs.

Capacity and Processing Time Limit
The charging capacity is calculated as the charging current multiplied by time. If the
charging capacity exceeds the maximum limit set by the user, the process will terminate
automatically. Additionally the user can set the maximum amount of charging time. If the
charging time exceeds this limit, the process will terminate automatically.
Temperature Threshold*
The battery's internal chemical reaction causes the temperature of the battery to rise
during the charging process. If the temperature exceeds the limit, the charging process
will automatically terminate.
* This function is available by connecting an optional temperature probe, which is not
included in our package.
5 User Customizable Presets per Port
Each port of the X2-400 features 5 individually customizable presets so the user can store
the charge and discharge parameters for any particular battery type. These presets can
be recalled for the desired battery type without the need for any additional programming.

Discharging
The main purpose of discharging a battery is to clean the residual capacity of the
battery or to reduce the battery’s voltage to a defined level. It is even more critical that
close attention be paid to the discharging process as failure to properly monitor the
process can destroy your batter. The final discharge voltage should be set correctly to
avoid deep discharging. Some rechargeable batteries have a memory effect. If they
are partly used and recharged before the complete charge/discharge cycle is accom-
plished, they remember this and will only use that part of their capacity next time. It is
generally known that NiCd and NiMH batteries suffer from this memory effect.
Discharging Lithium Batteries
Lithium batteries cannot be discharged to a voltage lower than the minimum voltage
for the cell type. Doing so will result in a rapid loss of capacity and/or total failure.
While the X2-400 monitors each individual cell during the discharge process the
discharging cutoff is based on the total pack voltage. Generally, lithium batteries don’t
need to be discharged and it is not recommended that you discharge them. If you do
choose to discharge your lithium batteries make sure to pay attention to the minimum
voltage setting as well as the individual cell voltage.

WARNINGSANDSAFETYINFORMATION
The Hitec X2-400 charger can also be powered by a 12VDC car battery using the
included large terminal clips with matching 4mm female bullet connectors or it can be
connected directly to a DC power supply. When connecting to a battery or power supply
it is critically important that you use either a fully charged 12 volt car battery or a high
quality DC power supply that has a voltage range between 12 to 18 volts DC and a
minimum current rating of 60 amps. Failure to use proper input power can result in unreli-
able performance and may damage the charger.

WARNING
DO NOT CONNECT A BATTERY TO THE CHARGER BEFORE SETTING
UP THE DEFAULT USER PREFERENCES
Main User Setup Screen
The first screen displayed is the Lithium battery set-up screen, you
can press ENTER to bypass this screen and go to the next user
setup screen, or you can set the default Lithium battery type before
moving on.
The Lithium Battery Select Screen
Here you can choose one of the three kinds of Lithium batteries
supported by the X2-400, LiFe (3.3V), Lilo (3.6V) or LiPo (3.7V). If
you plan to use one type of Lithium chemistry battery you can set the
default here. WARNING: Make sure when you connect your battery
that you have selected the proper type of battery before you begin
charging your battery. Once you have established the desired
settings press Start/Enter to confirm the setting then press INC to
move on to the next parameter.
LiPo /LiIo/LiFe Check Time
To avoid an erroneous setting by the user the X2-400 will automati-
cally detect the cell count of a Lithium battery at the beginning of the
charge or discharge process. To prevent an over-discharged battery
from being detected incorrectly, resulting in an error, you can set a
time limit for the processor to verify the cell count. The default setting
is 10 minutes which is typically enough time to properly detect the
cell count. It is not recommended that you change this setting as
setting to long of a “Check Time” can produce dangerous results.
Once you have established the desired settings press Start/Enter to
confirm the setting then press INC to move on to the next parameter.

NiMh & NiCd Delta Peak Sensitivity Setting
This feature sets the cutoff voltage for the automatic charge
termination of a NiMH and NiCd battery pack. The setting can
range from 5 to 20mV per cell, the default is 12mV for NiCd
batteries and 7mV for NiMH, the parameters are set individually
for NiCd and NiMh batteries. If the cutoff voltage is too high,
there is a danger of overcharging the battery, if it is too low there
is a possibility of premature charge termination. Refer to the
battery manufacturer’s specifications to determine the proper
setting. Once you have established the desired settings press
Start/Enter to confirm the setting then press INC to move on to
the next parameter.
Temperature Cutoff Setting
You can choose whether or not you want to use the automatic
temperature cut off when using the optional temperature
sensors. When turned on you can set the maximum temperature
at which the charger should allow the battery to reach during
charging. Once a battery reaches this temperature, the charge
or discharge process will be terminated to protect the battery.
Once you have established the desired settings press
Start/Enter to confirm the setting then press INC to move on to
the next parameter.
Waste Time Setting
When charge/discharge cycling a battery the battery will become
warm. You can set a time delay ranging from 0 to 60 minutes
after each charge/discharge process to allow the battery to cool
down before starting the next charge/discharge cycle. Once you
have established the desired settings press Start/Enter to
confirm the setting then press INC to move on to the next
parameter.
Safety Timer Setting
When the charge process starts, the integrated safety timer runs
simultaneously. If an error occurs or the charge termination
circuit cannot detect if the battery is fully charged, this setting will
terminate the charge process to prevent overcharging. Use the
Safety Timer Calculation below to determine the proper setting.
Safety Timer Setting Calculation
To determine the correct safety time setting when charging NiCd
or NiMH batteries, divide the capacity by the current, and then
divide the result by 11.9. Set the results of this calculation as the
number of minutes 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. Example: 2000mAh 2.0A
(2000/2.0=1000)/11.9=84 minutes.

A Lithium battery is charged at a
constant current until it reaches the
final charge voltage of 4.2 V per
cell (B). After this point the voltage
is kept at a constant level, and the
residual charge takes the form of a
declining current curve (C) until the
cut-off point (D) is reached. Charge
current = C/10. At this point you can
disconnect the battery from the
charger, as it is ready for use.
The final voltage of charge process is also very important; it should be precisely
matched with the charged voltage of the battery. They are 4.2V for LiPo, 4.1V for Lilon,
and 3.6V for LiFe. The charge current and the nominal voltage for the cell count on the
charge program must always be set correctly for the battery that is being charged.

Charging Lithium Battery in Balance Mode
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.
Charging Lithium Batteries in Fast Mode
When charging lithium chemistry batteries in the fast charge mode the charging current
will become lower towards the end of the charge cycle. In fast mode the charging capac-
ity is slightly lower than in normal charge mode, but charging time is reduced.

This screen, you can set up the current and voltage of the
battery pack. Charging and discharging will bring the batter-
ies to the storage level.
This screen shows the real-time status of the charge or
discharge process. Press the BATT TYPE/STOP key once to
stop the charging process.
NOTE
During the discharge process the X2-400’s Microprocessor monitors the voltage of each
cell during the Storage Mode or Discharge process. If the voltage of any cell is abnormal,
the charger will display an error message and immediately terminate the program.
Before disconnecting the battery review the error message then press the INC button to
display which cell is.
Charging Lithium Batteries in the Storage Mode
The Storage Mode function is for charging/discharging batteries that will not be used
immediately or that will be stored for a period of time. The program is designed for charg-
ing or discharging batteries to a specific voltage level depending on the type of battery
(Li-ion = 3.75V, LiPo = 3.85V and LiFe = 3.3V) The program will begin to discharge if the
original state of the battery exceeds the voltage level for storage.
WARNING: Lithium batteries cannot be discharged to a voltage lower than the minimum
voltage for the cell type. Doing so will result in a rapid loss of capacity and/or total failure.
While the X2-400 monitors each individual cell during the discharge process the discharg-
ing cutoff is based on the total pack voltage therefore it is important to watch the discharge
process closely to make sure a cell does not fall below the minimum voltage. Generally,
lithium batteries don’t need to be discharged and it is not recommended that you discharge
them. If you do choose to discharge your lithium batteries it is recommended that you cycle
them using use Storage Mode charging to cycle the batteries.
Error Message Display
This screen shows that the processor detected the voltage of
one on the cells is too low.
This screen shows the 4th cell was damaged. If the cell is
disconnected or not present the reading of the voltage will be
zero.

The setting of the discharge current on the left cannot exceed
1C, and the setting on the right cannot be under the voltage
recommended by the manufacturer to avoid deep discharg-
ing. Press the START/ENTER key for more than 3 seconds to
start discharging.
This shows the real-time status of discharging; you can press
the BATT TYPE/STOP key to stop discharging.
Charging NiCd or NiMh Batteries
This program is for charging NiCd/NiMH batteries typically
used in an R/C model application. Press the START/ENTER
key until the parameter you want to change begins to blink
then use the INC or DEC keys to change the value. Press the
START/ENTER key to store the setting.
This screen shows the real-time status of charging. You can
press the BATT TYPE/STOP key to stop the charge process.
There are two methods of charging NiCD and NiMh batteries, Manual or Auto Mode. When
in the NiMh or NiCd Program Select screen you can change modes by pressing the
START/ENTER key until the current field begins flashing then press INC and DEC simulta-
neously to switch between Auto and Manual Mode. using the charge current you set up. In
the“auto”mode,youshouldset the upper limitof the charge currentto avoid damage caused
by excessive charge current. This is especially important for low quality batteries that have
low resistance and capacity. In the “manual mode” the charger will only charge at the current
you set. Note the following charger / discharge specifications for NiCd and NiMh Batteries.
Nominal Voltage level: 1.2V/cell
Allowable Fast Charge Current: 1C-2C (depends on performance of cell)
Discharge Voltage Cut Off Level NiCd: 0.85V per cell
Discharge Voltage Cut Off Level NiMh: 1.0V per cell

Discharging NiCd or NiMh Batteries
Set the discharge current on the left and the voltage cutoff on
the right by pressing the START/ENTER key for more than 3
seconds to start the program. Discharge current can be set
from 0.1-5.0A and voltage cutoff from 0.1-25.0V.
This screen indicates the discharging state. You can press the
START/ENTER key to alter the discharge current. Press the
START/ENTER key again to store the setting. Press the BATT
TYPE/STOP key to stop discharging. The charger will emit a
sound to indicate the end of the discharge process.
Charge/Discharge Cycling Of NiCd/NiMh Batteries
Set the cycle sequence on the left and the number of cycles on
the right. The battery can be cycled 1-5 cycles.
Press the BATT TYPE/STOP key to stop the program then
press the START/ENTER key to alter the charge or discharge
current. A sound will indicate the end of the program.
When the charger approaches the end of the program cycle,
you can view the capacity of the battery being charged or
discharged. Use the INC or DEC keys to scroll through the
results of each cycle.
This program is only suitable for charging a lead-acid (PB) type battery with a nominal
voltage range of 2 to 20 volts. Lead acid (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 for lead acid (Pb) batteries is only 1/10 of its
rated capacity. You cannot fast charge lead acid (Pb) batteries. Please refer to the
following specification regarding charging and discharging lead acid (Pb) batteries.
Nominal Voltage Level: 2.0V per cell
Maximum Charge Voltage: 2.46V per cell
Allowable Charge Current: 0.4C or less
Discharge Voltage Cut Off Level: 1.75V or higher per cell
