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.
• See the status of individual Lithium cells (works in any
charge, discharge and storage modes)
• Capacity percentage
• Final voltage when the program ends
• Input voltage
• Safety timer and duration of time in minutes
• Cutoff temperature
• Internal and external temperature
(Temperature probe needs to be connected to show
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 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.

highly recommended to have these owcharts handy while
learning to operate this charger.
There are two main ways in which to set the charger.
1. A memory prole is available for setting and storing
pertinent information for up to 10 different batteries.
Once a battery’s information is stored into a memory it
will be retained until changed again manually. Recalling
a battery’s memory number makes the charger instantly
ready to go!
2. If you do not wish to use the battery memories, this
charger can be manually set before each use.
Manually setting:
3. BATT/PROGRAM Select
Press INC and DEC to go through all the
programs and press START/ENTER to enter
LiPo BATT Program.
4. Mode Select
Press INC and DEC to go through all the
modes and press START/ENTER to enter LiPo
Balance Charge Mode.
5. Battery Settting
Press START/ENTER. The current value will
start to blink. Press INC and DEC to change
the value and press START/ENTER to conrm
your setting.
At the same time, the battery cells number
will start to blink. Press INC and DEC to
change the value and press START/ENTER to
conrm your setting.
6. Program Start
Press and hold START/ENTER for 3 seconds
to start the program.
The charger is detecting the battery cell.
R shows the number of cells detected by the
charger and S is the number of cells set by
you at the previous screen. If both numbers
are not identical, press STOP to go back to
previous screen to recheck the number of
cells of the battery pack before going ahead.

Battery Memory Set and Use
The charger can store up to 10 different charge/discharge
proles for your convenience, and the stored proles can be
recalled quickly without having to go through the setup process.
When you are willing to alter the parameter value in the
program, press START/ENTER to make it blink then change
the value with INC or DEC. The value will be stored by
pressing START/ENTER once.
IMPORTANT: All following screens are using a 2S (7.4V)
LiPo battery as an example.
1. Battery Memory Set
Enter the battery memory program.
(10 different charge/discharge proles can
be stored).

Item Selection Description
Safety Timer
ON 120Min
OFF/ON
(1-720 Min)
When you start a charge process, the integral safety timer automatically starts running
at the same time. This is programmed to prevent overcharging the battery if it proves
to be faulty, or if the termination circuit cannot detect the battery full. The value for the
safety timer should be generous enough to allow a full charge of the battery.
Capacity Cut-Off
ON 5000mAH
OFF/ON
(100–50000 mAh)
This program sets the maximum charge capacity that will be supplied to the battery
during charge. If the delta peak voltage is not detected or the safety timer expires for any
reason, this feature will automatically stop the process at the selected capacity value.
Temp Cut-Off
On 50 C 122 F
OFF/ON
(20 C/68 F –
80 C/176 F)
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.
Temperature Unit

1–60Min A rest time allows the battery to cool down between charging/discharging cycles.
NiMH Sensitivity
D.Peak Default
Default: 4mV/Cell
3–15mV/Cell
This program is for NiMH/NiCd battery only. When the charger detects the delta peak
value you set, the charger will say the battery is fully charged.
A higher setting may be required in order to fully charge aged or under used batteries.
