Special Features - HITEC multi charger X4 AC Plus Mode D'emploi

Professional Balance Charger, Discharger

3. Special Features

The Hitec X4 AC Plus 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 confi guration 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 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 confi gured 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.
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.
Capaeity and Proeessing 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.
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.
10 User Customizable Presets
The X4 AC Plus 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.
Temperature Threshold*
The battery's internal chemical reaction causes the tempe-
rature 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 tem-
perature probe, which is not included in our package.
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.
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 Communieation*
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 lit-
hium battery pack. * Using optional PC-LlNK USB Adapter
(sold separately) and software that can be downloaded
from www.hitecrcd.com.
