INTRODUCTION Congratulations on your purchase of the Hitec X4 Multi-Charger. You are now the owner of a compact multi chemistry battery charger with battery management and integral Lithium battery balancing features. The X4 AC Plus features four totally independent and identical 50 watt charging circuits for a total power of 200 watts. As a result, it can simultaneously charge or discharge up to 4 separate battery packs.
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.
CHARGER LAYOUT LCD Screen Menu Control Buttons Battery Sockets Universal Balancing Port Pitch=2.54mm Temp.
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.
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.

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.
DEFAULT USER PREFERENCES SETUP When powered on for the first time the X4 will load a set of default parameters most commonly used by most users. The screen displays the information in the following sequence. The user can customize the parameters on each screen to suit their own preferences. To change the parameter values in the program, press the Start/Enter key to choose the parameter you want to change.
DEFAULT USER PREFERENCES SETUP NiMh & NiCd Delta Peak Sensitivity Setting DEC INC DEC INC DEC INC 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.
DEFAULT USER PREFERENCES SETUP Capacity Cutoff Setting DEC INC DEC INC The charging software allows the user to create a maximum charge capacity protection setting. If the delta-peak voltage is not properly detected or the safety timer times out, the charge process will stop automatically when the battery reaches the set maximum charge capacity set by the user. Once you have established the desired settings press Start/Enter to confirm the setting then press INC to move on to the next parameter.
PROGRAM FLOW CHART 12
PROGRAM DISPLAY INFORMATION You can view a variety of information on the LCD screen during the charge and discharge process. Press the DEC key to display and scroll through these settings. When connected to the balancing port you can monitor the voltage of each individual cell by pressing the INC key. When the program is completed, the final voltage is displayed. DEC When the capacity cutoff function is turned on, the capacity value is displayed.
CHARGING LITHIUM CHEMISTRY (LiPo/Lilo/LiFe) TYPE BATTERIES Lithium Ion (Li-Ion) Nominal Voltage Level: 3.6V per cell Max. Charge Voltage: 4.1V per cell Allowable Fast Charge Current: 1C or less Min. Discharge Voltage Cut Off Level: 2.5V per cell or higher Lithium Polymer (Li-Po) Nominal Voltage Level: 3.7V per cell Max. Charge Voltage: 4.2V per cell Allowable Fast Charge Current: 1C or less Discharge Voltage Cut Off Level: 3.0V per cell or higher Lithium Ferrite (LiFe) Nominal Voltage Level: 3.
CHARGING LITHIUM CHEMISTRY (LiPo/Lilo/LiFe) TYPE BATTERIES 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 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.
DISCHARGING LITHIUM CHEMISTRY (LiPo/Lilo/LiFe) TYPE BATTERIES DEC INC Batt Type Stop DEC INC Start ‘>3 seconds’ Enter 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 discharging. 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/ DISCHARGING AND CYCLING NiCd OR NiMh BATTERIES 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 0.1-1.0A and voltage cutoff from 0.1-25.0V. DEC INC DEC INC Batt Type Stop Start ‘>3 seconds’ Enter This screen indicates the discharging state. You can press the START/ENTER key to alter the discharge current.
CHARGING / DISCHARGING LEAD-ACID (PB) BATTERIES NOTICE Due to the chemistry characteristic of a Pb battery, the cut-off point may be difficult to detect at times. We recommend you use the CAPACITY CUT-OFF feature to protect the battery. Refer to the Default User Preferences Setup section of this manual to set up this feature. Charging Lead Acid (Pb) Batteries DEC INC Batt Type Stop DEC INC Start ‘>3 seconds’ Enter Set the charge current on the left and the nominal voltage on the right.
BATTERY DATA PRESET STORAGE AND LOAD FEATURE For your convenience, the X4 has a data storage and load program that can store up to five preset battery charge or discharge configurations. You can recall these settings when charging or discharging without having to setup the program again. To get to the save data screen press the BATT. TYPE/ STOP button until you see the Save Data screen. Press the START/ENTER key to modify the menu, and use the INC or DEC to change the parameters.
WARNING AND ERROR MESSAGES The X4 incorporates a variety of systems to verify the various charge/discharge processes and the overall state of the electronics. In case of an error, the charger will emit an audible alarm and the screen will display the cause of the error. See the following description of the errors and their possible causes. Incorrect polarity connected. Battery connection is interrupted. Short circuit on the battery connection. Incorrect input voltage.
