We raised the bar on the X4 and equipped it with a built-in AC
power supply. Our 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.
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
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
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
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
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
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.
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*
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.
