leads. Reverse the sequence when disconnecting.
• Always connect the positive red leads (+) and negative
black leads (–) correctly.
• Always disconnect the battery after charging, and let the
charger cool between charges.
• Always charge in a well-ventilated area.
• Always terminate all processes and contact Horizon Hobby if
the product malfunctions.
• Always supervise children and ensure they DO NOT play
with or attempt to use this appliance.
WARNING: Never leave charger unattended, exceed
maximum charge rate, charge with non-approved
batteries or charge batteries in the wrong mode. Failure to
comply may result in excessive heat, re and serious injury.
CAUTION: Always ensure the battery you are
charging meets the specications of this charger and
that the charger settings are correct. Not doing so can result
in excessive heat and other related product malfunctions,
which can lead to user injury or property damage. Please
contact Horizon Hobby or an authorized retailer with
compatibility questions.

Special Features
DC Power Supply
The Onyx®KX80 is integrated with a DC power supply
function with a 13.8V output and 10W–80W power range.
AGM Charge and Cold Charge
For Pb batteries, there are two charging modes: AGM charge
and cold charge.
Optimized Operating Software
The Onyx KX80 features an AUTO function that automatically
sets the current during charging/discharging. When charging
lithium batteries, this may prevent overcharging. If the
charger detects a malfunction, it will disconnect the circuit
automatically and sound an alarm. You can congure the
settings accordingly.
Battery Memory (Data Store/Load)
Store up to 10 different charge/discharge proles for each
channel. You can keep the data pertaining to program setting
of the battery of continuous charging or discharging. Users
can call out these data at any time without any special
program setting.
Terminal Voltage Control (TVC)
TVC is the maximum voltage that a cell within a pack will
charge to. Users cannot charge above the maximum voltage;
however, users can charge to a lower termanal voltage, which
will not fully charge a battery.
Internal Independent Lithium Battery Balancer
The Onyx KX80 features an individual cell voltage balancer,
rendering an external balancer for balance charging
unnecessary.
Balancing Individual Cells Battery During Discharging
During the process of discharging, the Onyx KX80 can
monitor and balance each cell of the battery individually. An
error message appears and the process automatically stops if
the voltage of a single cell is abnormal.
• See the status of individual Lithium cells (works with any
charge, discharge and storage mode)
• Capacity percentage
• Final voltage when the program ends
• Input voltage
• Safety timer and duration of time in minutes
• Cutoff temperature
• Internal and external temperature (Connect temperature
probe to display external temperature.)
• Capacity cut-off and value of the set capacity limit
Fast Charge and Storage Mode of Lithium Battery
Fast charge mode shortens the overall charge time required
for lithium batteries with a slight reduction in overall capacity.
Storage mode is used for charging or discharging lithium
batteries not used for an extended period.
Re-Peak Mode of NiMH/NiCd Battery
In re-peak charge mode, the charger can peak charge the
battery one, two, or three times in a row automatically.
Delta-Peak Sensitivity for NiMH/NiCd Battery
When the battery’s voltage exceeds the threshold, the process
automatically terminates.
Cyclic Charging/Discharging
A series of 1 to 5 charge to discharge (>) or discharge to
charge cycles can be used for refreshing older batteries and
improving cell balance.
Automatic Charging Current Limit
Allows you to set the upper limit of the charging current when
charging your NiMH or NiCd battery.
Battery Meter
Allows you to check battery voltage and internal resistance.
Battery Internal Resistance Meter
Allows you to check the battery’s total internal resistance as
well as each cell’s internal resistance.
Capacity Limit
The charging capacity is always calculated as the charging
current multiplied by time. If the charging capacity exceeds
the limit, the process automatically terminates when the
maximum value is reached.
Temperature Threshold
The battery’s internal chemical reaction causes the battery
temperature to rise. The process terminates if the temperature
limit is reached. This function is only available when
connecting the optional temperature probe (DYN5033).
Processing Time Limit
Allows you to limit the maximum process time to avoid
overcharging the battery.
