INTRODUCTION
The Hitec X4 allows you to charge up to four different batteries simultaneously. The
charger will automatically charge all 4 batteries at a time to their maximum capacity. Additionally 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.

SPECIAL FEATURES
Optimized Operating Software
The software in X4 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 X4 AC
Plus 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 configured by the
user.
Internal Independent Lithium Battery Balancers
Each channel of the X4 employs an individual-cell voltage balancer eliminating the need
for an external balancer for balance charging.
Balancing Individual Cells during Battery Discharging
During the process of discharging, the X4 can monitor and balance each cell of the
lithium battery 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 X4 is compatible with the three most common Lithium chemistry batteries, Li-Ion,
LiPo and LiFe.
Multiple Lithium Battery Charge Modes
The X4’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 X4 will auto-detect when the batteries are fully charged and shut off, even with low
impedance NiMH packs.
04
SPECIAL FEATURES
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
The X4 features 10 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.
Cyclic Charging / Discharging
Batteries can be set to automatically Charge/Discharge or Discharge/Charge up to a
maximum of 5 cycles.
PC Based Analysis Using USB Communication*
The Hitec X4 offers a PC-based program which can analyze the characteristics of the
battery via a USB port. It shows a graph of voltage, current and capacity curves. It also
displays the individual voltage of each cell in the lithium battery pack.
* Using optional PC-LINK USB Adapter (sold separately) and software that can be
downloaded from www.hitecrcd.com

WARNINGS AND SAFETY INFORMATION
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 critical that the same
attention be paid to the discharging process as to the charging process. The final
discharge voltage should be set correctly to avoid deep discharging. Lithium batteries
cannot be discharged to voltage lower than the minimum voltage for the cell type.
Doing so will result in a rapid loss of capacity and/or total failure. Generally, lithium
batteries don’t need to be discharged and it is not recommended. If you choose to
discharge your lithium batteries make sure to pay attention to the minimum voltage
setting.
Some rechargeable batteries have a memory effect. If they are partly used and
recharged before the complete charge/discharge cycle is accomplished, 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.

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

CHARGING LITHIUM CHEMISTRY (LiPo/Lilo/LiFe) TYPE BATTERIES
NOTE
During the discharge process the X4’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 charging 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.
This screen, you can set up the current and voltage of the
battery pack. Charging and discharging will bring the batteries to the storage level.

DISCHARGING LITHIUM CHEMISTRY (LiPo/Lilo/LiFe) TYPE BATTERIES
Lithium batteries are recommended to be discharged partially rather than fully. Frequent
full discharging should be avoided if at all possible. Instead, charge the battery more often
or use a battery of larger capacity. Full capacity cannot be reached 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.

START/ENTER key until the current field begins flashing then press INC and DEC simultaneously to switch between Auto and Manual Mode. using the charge current you set up. In
the “auto” mode, you should set the upper limit of the charge current to 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)

CHARGING / DISCHARGING LEAD-ACID (PB) BATTERIES
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
