Optimized Operating Software

The software in X4-80 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 X4-80
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 X4-80 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 X4-80 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 X4-80 is compatible with the three most common Lithium chemistry batteries, Li-Ion,
LiPo and LiFe.

Multiple Lithium Battery Charge Modes

The X4-80’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 X4-80 will auto-detect when the batteries are fully charged and shut off, even with
low impedance NiMH packs.
