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.

Special Features
Dual Channel Charger
The Onyx® 350 allows you to charge 2 batteries with different
chemistries simultaneously, and it will intelligently and
automatically initiate the charging to their maximum capacity.
Power of each channel is 100W.
Optimized Operating Software
The Onyx 350 features an AUTO function that automatically
sets the current during charging/discharging. When charging
lithium batteries, this may prevent overcharging, which may
lead to a re. If the charger detects a malfunction, it will
disconnect the circuit automatically and sound an alarm.
Settings can be con gured by the user.
Balance Voltage Calibration
The Onyx 350 allows you to calibrate the balance voltage
with a 6S LiPo battery. (For more information please contact
Horizon Product support)
Memory of Last Operation
The Onyx 350 will memorize your last operation of charging/
discharging before powering down.
AGM Charge and Cold Charge
For Pb batteries, there are two charging modes: AGM charge
and Cold charge.
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)
Allows user to change the end voltage. (for expert user only)
Balancing Individual Cells Battery During Discharging
During the process of discharging, the Onyx 350 can
monitor and balance each cell of the battery individually.
An error message will be appear and the process will end
automatically if the voltage of any single one cell is abnormal.

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 that will not be used for an extended period of time.
Re-Peak Mode of NiMH/NiCd Battery
In re-peak charge mode, the charger can peak charge the
battery once, twice or three times in a row automatically. This
is good for making sure the battery is fully charged.
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
improve cell balance.
Automatic Charging Current Limit
Set the upper limit of the charging current when charging
your NiMH or NiCd battery, battery. This is useful for NiMH
batteries with low impedance and capacity in the ‘AUTO’
charging mode.
Battery Voltage Meter
Check battery’s total voltage, the highest voltage, the lowest
voltage and each cell’s voltage.
Battery Internal Resistance Meter
Check battery voltage and battery 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 will be terminated automatically when
you reach the set maximum value.
Temperature Threshold
The battery’s internal chemical reaction will cause the
temperature of the battery to rise. If the temperature limit
is reached, the process will be terminated. This function is
only available by connecting the optional temperature probe
(DYN5033).
Processing Time Limit
You can limit the maximum process time to avoid
overcharging the battery.
