AC/DC DUAL
CHARGER W/BALANCING
INSTRUCTION
MANUAL
®
Charge rates up to 6A, plus the ability to charge 1-15 nickel-based or 1-6S lithium cells, make the Onyx 255 a match for
any charging need. Dual outputs make it an especially good choice for models that use two packs simultaneously and
modelers who run and recharge multiple batteries in a single session. Both outputs can peak charge NiCd/NiMH cells,
and balance 2-6S lithium packs for maximum voltage. Separate jacks make it as useful for radio packs as power packs.
Simple menus, push-button controls and a backlit, reversed matrixed LCD make it easy to use anytime, in any lighting,
anywhere there’s AC or DC power.
It is strongly recommended to completely read this manual before use! Damage resulting
from misuse or modification will void your warranty.
WARNING!! Charging lithium-based rechargeable batteries poses a risk of FIRE! NEVER
treat lithium-based batteries in the same manner as other battery types. NEVER leave
lithium batteries unattended while being charged! ALWAYS charge lithium-based batteries
in a fireproof location! Failure to follow all care and handling instructions contained in this
manual could result in quick, severe, permanent damage to the batteries and all surroundings!!
Follow all safety precautions when using such batteries, as listed on page 3 of this manual!

GLOSSARY OF TERMS
Amps (A): The unit of measure for charge current.
Milli-amps (mA): A unit of measure for current, being amps (A) multiplied by 1000 and listed as “mA”. So 2.5A is the
same as 2500mA (2.5  1000). Or, to convert mA to amps, divide the mA number by 1000. So 25mA is the same as
0.025A (25 divided by 1000).
Capacity and milli-amp hours (mAh): The amount of energy a battery can store is called its capacity, which is defined
as how much current a battery can supply constantly over one hour of time. Most hobby batteries are rated for capacity
in “mAh” or milli-amp hours. A 650mAh battery can deliver 650mA of current for one hour (650mA  1hr = 650mAh). A
3200mAh battery can deliver 3200mA (3.2A) of current for one hour (3200mA  1hr = 3200 mAh), etc.
“C” rating: Capacity is also referred to as the “C” rating. Some battery suppliers recommend charge currents based on
the battery’s “C” rating. A battery’s “1C” current is the same number as the battery’s rated capacity number, but noted
in mA or amps. A 600mAh battery has a 1C current value of 600mA, and a 3C current value of (3  600mA) 1800mA or
1.8A. The 1C current value for a 3200mAh battery would be 3200mA (3.2A), etc.
INPUT POWER
AC Input: For indoor use, this charger includes a built-in switching AC power supply that delivers power by connecting
the AC power cord to a common 110V AC outlet.
DC Input: This charger can be powered by a portable 12V DC power source. Located on the rear of the charger is a jack
for the connection of the DC power cord. Once connected to the charger, connect the DC power cord to the 12V power
source. Always match polarities (red lead to red “+” terminal, black lead to black “–” terminal). To utilize the charger’s
absolute maximum power capabilities the DC power source must be capable of delivering at least 9 amps while
maintaining 12 volts DC.
WARNING! Never accidentally short together the positive (+) and negative (–) input connections
when connected to 12V DC power. Failure to do so could result in permanent damage to the power
source and the charger.
This charger is rated for a maximum output power of 60 watts. Depending on certain conditions (if charge current is set
to maximum, the maximum number of cells are connected to the output, and input voltage is low), the actual current
delivered to the battery might be slightly less than the setting. This is normal.
The charger will be on at all times when connected to input power. Disconnect the charger from input power when not in use.

4. If none of the memories have settings which meet your needs, proceed to the ADJUSTABLE SETTINGS section
below to change settings manually.
ADJUSTABLE SETTINGS
1. Select the memory (0 through 9) that you wish to modify.
2. Press
to find the “BATTERY SETUP” screen.
3. Press to move down to the BATTERY TYPE screen. Press CHANGE to cause the setting to flash, then press (+)
or (–) to find the desired battery type. Press CHANGE to confirm the new setting.
WARNING! NEVER set the BATTERY TYPE screen to a type that does not match your battery! For
example, accidentally charging a LiPo battery in the NiCd setting could result in an overcharge
condition on the battery, which could result in an intense FIRE!
4. Press to find the CELL screen, to set the number of cells / nominal rated voltage of the battery. The number of
cells in the pack is shown on the top line, and the nominal rated voltage of the pack will show on the bottom line.
Press CHANGE to cause the setting to flash, then press (+) or (–) to find the setting which matches your pack. Press
CHANGE again to confirm the new setting.
WARNING! For LiPo and LiIon batteries, NEVER set the voltage to a value which is higher than the
rated voltage printed on the battery! Attempting to charge such a battery to a voltage that is higher
than its rating could result in an overcharge condition on the battery, which could result in a very
intense FIRE!
5. Press to find the CAPACITY screen. If the charger fails to detect full charge, this function can stop the charge
process after a certain amount of energy (mAh) has been delivered to the battery. This protects the battery from
accidental overcharge.
WARNING!! For LiPo, LiIon, and LiFe cells, always set the value in this screen to the exact rated
capacity of the battery (or as close as possible). Lithium battery types can EASILY BECOME
DAMAGED if overcharged and possibly START A FIRE! NEVER set the number in this screen to a
value higher than the capacity (mAh) value printed on the lithium battery.
Setting this screen to 110 –130% of a NiCd or NiMH battery’s rated “mAh” value is recommended. As shown in the
quick reference chart on page 6, locate the rated capacity of your battery in the left column, then find your battery’s
110% or 130% capacity value to the right. Enter the desired capacity value into this screen.
Press CHANGE to cause the setting to flash, then press (+) or (–) to find the proper capacity value (as close as
possible). Press CHANGE to confirm the new setting.
6. Press
to find the fast charge CURRENT screen:
a. For lithium based batteries, the charger will automatically set the charge current to a value of 1C (based on the
value entered in the CAPACITY screen described above). This can be overridden manually.
5
b. For NiCd and NiMH batteries, refer to the chart here for
recommended currents, based on the size of your battery
shown in the left column. NOTE: if applying a slow charge
to the battery as shown in the chart at right, it will be
necessary to set the S_TIMER function to “off” (see below).

c. To change the setting, press CHANGE to cause the setting
to flash, then press (+) or (–) to find the proper capacity
value. Press CHANGE to confirm the new setting. Do not
exceed the maximum rated charge current for the battery.
7. Press to find the S_TIMER screen. This is a backup safety
timer designed to automatically stop fast charge if the battery
has not reached full charge in a reasonable amount of time.
The charger will automatically calculate and set this time
in minutes based on the values entered in the current and
capacity screens above.
To manually adjust this value, press CHANGE to cause the
setting to flash. Press (+) or (–) to adjust the value. Press
CHANGE again to confirm the setting. Do not increase this
value so far that the charger no longer offers overcharge
protection.
8. Press to find the DELTA PEAK V screen (NiCd and NiMH
batteries only). This “peak sensitivity” function determines
how well the peak detection circuit will fill the battery. Settings
of 8-10mV for NiCd batteries, and 3–7mV for NiMH batteries
are recommended. Lower values usually result in more precise
peak detection, but unstable input power sources could cause
the charger to errantly stop peak charge too early. Larger
values could cause the battery to generate a little extra heat
during charge, and result in slightly less accurate peak charges.
9. Press to find the TRICKLE charge current screen. This is
the amount of trickle charge current that will be applied only
to NiCd or NiMH batteries after peak charge has ended. The
charger will automatically set this value based on the fast
charge current setting divided by 20. This setting can be
manually changed if desired. Setting this to “0mA” effectively
turns this feature off. For “A”, “AA”, “AAA” size Tx or Rx
batteries, it is not recommended to set the trickle current to
larger than 50mA. Trickle charge is never applied to lithium
batteries.
Once you’ve customized a memory to match your battery, the
charger will memorize these settings until changed again manually.
For easy reference, record your settings for each memory in the
blank chart below.
After settings have been adjusted, press repeatedly to find the
BATT SETUP screen, or press to find the START screen.

connected to an AC input, that voltage is converted to a DC voltage inside the charger and will be displayed in this
screen.
2. The OUTPUT VOLTAGE screen shows the DC voltage measured on the charger’s output.
3. The PEAK VOLTAGE screen shows the highest measured battery voltage during the last charge.
4. The CHG CAPACITY screen shows how much charge energy was delivered to the battery during the last charge.
5. The CHG TIME screen shows how many minutes the charger delivered a charge to the battery. This does not include
any time that a trickle charge was delivered.
6. Press
to return to the START screen.
BATTERY CONNECTION
1. After determining which battery type is to be charged, what connector is being used and all appropriate
programming is completed, the correct adapter will need to be installed prior to charging. If an adapter other than
what is included is needed, please refer to the ‘CONTROLS AND CONNECTIONS’ section on page 4 for a list of
adapters that are sold separately.
2. For NiCd/NiMH: Plug the adapter into the charger FIRST. Then connect the battery to the adapter ONLY after it has
been connected to the charger. Proceed to the ‘Starting Charge’ section.
3. For LiPo, LiIon OR LiFe: Lithium batteries for R/C are commonly available in two different assembly/wiring
configurations: wired for balancing, and non-balanced. It’s important to know which configuration you have before
proceeding. Consult your battery supplier if you are unsure if your battery is wired for balancing, if it’s not
wired for balancing but has a built-in safety circuit, or neither.
WARNING! It is NOT recommended to charge a LiPo battery which is not wired for balancing, or
which does not have a built-in protection circuit! Such types of LiPo batteries have NO means to
protect the equipment or the user from damage that could result from an overcharge condition of
any single cell in the pack.
Packs wired for BALANCING have a unique connector which has more than two
wires going to the pack itself (like shown at right.) Each wire is connected to an
individual cell inside the pack, by which the charger monitors the condition of the
individual cell and controls whether it should be charged. Such packs SHOULD be
charged with a LiPo charger that is capable of balancing, such as the Onyx 255.
Balancing Connector
NON-BALANCED packs are wired so the charger can only detect the voltage of
the entire pack (not individual cells), so there is only one charge lead. It’s highly
recommended to ONLY use such types of LiPo packs if they have a built-in charge
safety circuit which prevents any single cell in the pack from being overcharged.
Simply connect the battery’s main power lead to the charger’s banana jacks (note
proper polarity).

4. To balance a LiPo battery during charge, connect the balance board adapter to the charger’s balancing jack (above
left). The red wire will always be on the left. Next, connect the charge lead adapter that matches your battery
connector type to the charger’s banana jacks. Then connect the battery’s balance lead to the balancing board.
Lastly, connect the battery’s main power lead to the adapter connected to the charger’s banana jacks (note proper
polarity, shown above right).
It is highly recommended to use a LiPo charge bag, such as the ElectriFly
SafeCharge™ LiPo battery charge bag, when charging LiPo batteries. This bag
is intended to reduce the effects that might occur if a LiPo battery experiences a
failure while being charged. If a LiPo battery suffers damage while being charged
inside the SafeCharge LiPo charge bag, the high-temperature material and coating will add a
layer of safety to suppress flames from exiting the bag. Please follow all instructions and safety
information included with the LiPo battery and SafeCharge LiPo charging bag. Note that the
ElectriFly SafeCharge bag is only rated for up to 11.1V 3200mAh LiPo battery.

For NiCd and NiMH batteries, a linear charge current will be delivered to the battery. The peak detection method will be
used to accurately look for the highest battery voltage during charge. Once this is detected, the charger will automatically
stop fast charge and go to trickle charge mode.
CAUTION: Make sure the charge current setting is safe for your battery to prevent overheating of the cells. “AAA”, “AA”,
“A”, and “2/3A” size batteries generate heat more quickly than large sub-C batteries. Most radio batteries should NOT
be charged at currents greater than 1.5A. Failure to follow this recommendation could permanently damage your battery.
Lithium batteries are charged using the “constant current/constant voltage” method (cc/cv). Constant current is delivered
during the first part of fast charge. When the battery reaches a pre-set voltage, constant current is no longer delivered, and
a constant voltage is applied to the battery. As the battery’s voltage becomes equalized to the voltage on the charger’s
output, charge current will steadily begin to drop. This is normal. When current reaches an approximate value of 1/10C,
the charge process will end completely.
When the “CHARGE VOLTAGE” screen shows the voltage of the battery during charge, the loading affect of the charger
will skew the voltage reading of the battery, which is normal. A higher current will skew the reading more than a smaller
current. Voltage readings taken when charge is finished will more accurately show the true voltage of the battery.
To manually stop a charge while in progress, either disconnect the battery from the charger or press START.
CHARGE COMPLETE
When the charger has determined that the battery is full and fast charge ends, audible tones will sound for about 10
seconds and a new set of screens will show final results of the charge process like below:

For NiCd and NiMH batteries, the charger will automatically apply a trickle charge to the battery when peak charge ends,
shown in amps “A” on-screen. A trickle current of 200mA will be displayed as “0.20A”. A trickle current of 50mA will be
shown as “0.05A”, etc. The charger will remain in trickle charge mode until the battery is disconnected, or the START
button is pressed.
Trickle charge will NOT be applied to lithium batteries. When fast charge ends, lithium batteries can be disconnected from
the charger and are ready for use.
If the fast charge backup safety timer expires before the battery is fully charged, the display will show “TIMEOUT”. If
this occurs, you might want to attempt to re-peak the battery by starting another charge. Refer to the TroubleShooting
Guide for more details.
To exit the “CHARGE COMPLETE” screens, press to find the START screen. Then, pressing
screen is found will show all data relating to the last charge that was performed.

CARE AND HANDLING OF NiMH BATTERIES
● Do not to allow NiMH batteries to overheat! Disconnect overheated batteries from the charger immediately and
allow to cool.
● Do not attempt to use the charger’s lithium functions with NiMH batteries.
● Store NiMH packs with some voltage remaining on the cells (refer to battery supplier).
● It is important to recharge NiMH batteries immediately prior to use, as they have a high self discharge rate.
● “AAA”, “AA” and “A” size radio batteries can safely be peak charged at currents up to 1.5C to 2C (battery capacity 
1.5 or 2.0). High charge currents can overheat batteries and thus reduce service life, especially for smaller size cells.
CARE AND HANDLING OF LiPo, LiIon, and LiFe BATTERIES
WARNING!! DO NOT try to charge lithium-polymer (LiPo) or lithium-ion (LiIon) or lithium-ferritephosphate (LiFe) cells in the same way as other battery types! Always read the instructions that are
included with your lithium batteries carefully before use. Failure to follow these care and handling
instructions can quickly result in severe, permanent damage to the batteries and their surroundings
and even start a FIRE!
● ALWAYS charge lithium batteries in a fireproof location, which could be a container made of metal or
ceramic tile. Monitor the area with a smoke or fire alarm, and have a lithium approved fire extinguisher
available at all times.
● NEVER attempt to use the charger’s NiCd and NiMH functions for LiPo, LiIon or LiFe batteries.
● NEVER attempt to extinguish a lithium fire with water or a non-lithium approved fire extinguisher!
● ALWAYS provide adequate ventilation around LiPo/LiIon/LiFe batteries during charge, while in use, and during storage.
● NEVER allow LiPo, LiIon or LiFe cells to overheat at any time, as they can and usually will become physically
damaged and could possibly EXPLODE or catch FIRE!! If a battery becomes overheated (over 140°F, 60°C),
disconnect it from the charger IMMEDIATELY!
● NEVER continue to charge LiPo, LiIon or LiFe batteries if the charger fails to recognize full charge. LiPo and LiFe
cells which swell or emit smoke may be in an overcharge condition and should be disconnected from the charger
immediately.
● NEVER set the charger’s LiPo/LiIon/LiFe battery voltage settings to a voltage that is HIGHER than the nominal
rating of the battery itself, as such cells cannot handle overcharging in any way.
● NEVER charge LiPo, LiIon or LiFe batteries at currents greater than the “1C” rating of the battery, or the maximum
rated current as specified by the battery’s manufacturer.
● NEVER allow LiPo, LiIon or LiFe cells to come in contact with moisture or water at any time.
● NEVER allow the internal electrolyte from LiPo, LiIon or LiFe batteries to get in the eyes or on skin – wash affected
areas immediately if they come in contact with the electrolyte and contact your physician!
● ALWAYS keep LiPo, LiIon or LiFe batteries away from children.
BATTERY STORAGE
NiCd, NiMH, LiPo, LiIon and LiFe cell manufacturers recommend applying a 40% full charge to the batteries before being
put in storage. To achieve this, setting the CAPACITY screen to a reduced level before charge will cause the charger to
deliver only a partial charge to the battery.
Multiply your battery’s rated capacity by 0.4 to find the proper value. Enter this value (or the closest available value) into
this screen. For example: The 40% full charge capacity of a battery rated at 3200mAh would be (3200  0.4) 1280mAh.
The closest possible setting for this would be 1300mAh. The 40% full charge capacity of a battery rated at 1600mAh
would be (1600  0.4) 640mAh. The closest possible setting for this would be 650mAh.
Once this value is set, proceed to charge the battery. When charge ends, you should notice that only about 40% of the
battery’s rated capacity was delivered during charge by looking at the “COMPLETE” screen as explained above.
COOLING FAN
A built-in cooling fan helps to keep the charger cool during operation. This will help extend the service life of the charger,
and allow it to function more accurately and efficiently. The fan only functions while a battery is being charged. CAUTION:
Do not block the vent holes for the cooling fan on the left side of the charger. Failure to do so could cause the
charger to overheat and possibly cause permanent damage.
