Hitec X4 AC Plus 4-Port AC/DC Multi-Charger

Hitec raised the bar on the X4 and equipped it with a built-in AC power supply. The new X4 AC Plus has four-port computer-controlled capability with a built-in 22 amp power supply which can be powered by standard 120 volt AC household current. Simple to use and utterly reliable, this compact charger with battery management and integral balancer features four identical and independent 50-watt power outputs, for a total output power of 200 watts. Each port of the X4 AC Plus can handle up to a 6S Lithium pack, 15 NiCd/NiMH cells or 6-12 volt lead acid batteries. Four individual balancing ports eliminate the need for a separate balancer when charging Lithium batteries. Its twin-fan cooling system with an internal sensor for controlling fan speed provides the utmost in efficiency and safety. The X4 AC Plus can accept a variety of power inputs including the option of attaching it to a 12-volt car battery or a 11–15 volt (20 amp minimum) DC power supply.

The Hitec X4 AC Plus charger offers a complete charging solution for novice and expert RC enthusiasts alike. The multi-tasking versatility of this new charger makes it a perfect fit for nitro and electric modelers, regardless of what you drive, hover, float or fly.

Special Features:

Optimized Operating Software
The software in X4 AC Plus 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 AC Plus 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 AC Plus 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 AC Plus is compatible with the three most common Lithium chemistry batteries, Li-Ion, LiPo and LiFe

Multiple Lithium Battery Charge Modes
The X4 AC Plus's programming allows for Fast Charge, Balance Charge or Storage Charge Modes for LiPo, Li-Ion, and LiFe batteries.

  • Fast Charge Mode: Reduces charging time, but does not balance the cells, this mode only charges the battery to approximately 90% capacity.
  • Balance Charge Mode: Monitors individual cell voltage, keeping the cells within an acceptable voltage range and charges the pack to peak capacity.
  • Storage Charge Mode: 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 AC Plus 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 Channel
The X4 AC Plus 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.

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 AC Plus 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.
* A PC-LINK USB adaptor can be purchased separately.

Customer Reviews

Awesome charger, cuts charging time down immensely. Review by Iced51
Made the mistake of buying a charger that I couldn't grow with, then ended up buying a second. Charging two batteries at a time is great, being able to charge 4 at a time is killer. Rather than use a parallel charge board I would rather each battery have its own circuit. The majority of my batteries are 2200 and 1300 3S packs. This knocks out 4 2200 3S's in 40 minutes give or take. My favorite part of this charger is the storage mode. Hook up 4 batteries to it and regardless of how much charge or discharge the battery needs, the charger automatically puts the cells to 3,8V. Makes after flight battery maintenance a breeze. Highly recommended. (Posted on 12/15/13)
Hitec 4 ac/dc Review by Goldfever
No question about the best charger out there for the guys that make 4 flights every time you go out.I sit on my padio and put my 2200 3s batterys on charge have a soda and a bag of chips the beepers go off around a 1/2 hour -I always balance charge,I take them off put them in the ammo box I am done till tommorrow,our field has no electricity,even if it did I like to go to the field with charged batterys and make flight then take it easy watch the other pilots fly.Four flights works good for me,and this charger kept me into hobby of electrics I was about to quit flying electrics,I was chargeing with a sky charger single good charger but 2 to 2 1/2 hours a night was to long for me.I am very careful with lipos I like to be in the same area as where I am charging -I am going flying today Thangiving here AZ about 70 degrees later Ike (Posted on 11/28/13)
happy customer Review by will
Had this charger for over a year.Its the best charger I ever had. It does everything you would possibility want!!!!!. But would be nice to have 4 wire charge leads to put your own connector.Great anyway

Thanks. Will. (Posted on 11/12/12)
