INSTRUCTION
MANUAL
DTXP4195
The Onyx 150 AC/DC LiPo balancing charger is the perfect entry-level LiPo charger for modelers using up to 3S LiPo
batteries. Inexpensive and very easy to operate, the Onyx 150 utilizes the CC/CV charge method, with voltages customized
for LiPo batteries. Capable of operating from 110V AC or 12V DC input sources, this tiny, lightweight charger is perfect for
use at home or in the fi eld. Selectable charge currents range from 1.5A to 5A and a built-in balancing function ensures all
cells are charged to optimum voltage every time.
It is strongly recommended to read this manual completely before use! Damage resulting
from misuse or modifi cation 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 fi reproof 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!

IMPORTANT PRECAUTIONS
● Do not leave the charger unattended while in use.
● Disconnect the battery and remove input power from the charger immediately if the charger
or battery becomes hot!!
● Disconnect the battery if it begins to swell while being charged!
● Do not attempt to charge any battery types other than LiPo as permanent damage to the battery and charger could result.
● Do not use automotive type battery chargers to power the charger.
● Do not allow water, moisture or foreign objects into the charger.
● Do not block the fan or air intake holes, which could cause the charger to overheat.
● Do not attempt to use batteries with more cells or total voltage than listed in the specifi cations.
● Do not place the charger or battery on fl ammable surfaces or near combustible materials while in use, such as carpet,
cluttered workbench, paper, plastic, vinyl, leather, and wood, inside an R/C model or full sized automobile.
● Do not overcharge batteries as permanent damage could result. Do not use a charge current that exceeds the safe
level of the battery.
● Do not connect the charger to AC and DC inputs at the same time.
● Allow the charger and battery to cool down between charges.
● Always disconnect from power source when not in use.
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 defi ned
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 = 650 mAh). 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 U.S. 110V AC outlet.
DC Input: This charger can be powered by a portable 12V DC power source for use at the track. On the left side of the
charger, connect the DC power cord’s alligator clips directly to the output terminals on the 12V DC 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 7 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.
The charger will be on at all times when connected to input power. Disconnect the charger from input power when not in use.
CONTROLS AND CONNECTIONS
CARE AND HANDLING OF LiPo BATTERIES
●
● ALWAYS use a LiPo charge bag when charging LiPo batteries, such as the Great Planes
● NEVER attempt to extinguish a lithium fi re with water or a non-lithium approved fi re extinguisher! Use ONLY a
● ALWAYS provide adequate ventilation around LiPo batteries during charge, while in use, and during storage.
● NEVER allow LiPo cells to overheat at any time, as they can and usually will become physically damaged and
● NEVER continue to charge LiPo batteries if the charger fails to recognize full charge. LiPo cells which swell or emit
● NEVER charge LiPo batteries at currents greater than the maximum rated current as specifi ed by the battery’s
● NEVER allow LiPo cells to come in contact with moisture or water at any time.
● NEVER allow the internal electrolyte from LiPo batteries to get in the eyes or on skin – wash affected areas
● ALWAYS keep lithium batteries away from children.
DETERMINING BATTERY SPECIFICATIONS
Always read your battery’s label and/or instruction sheet before use.
Check to determine how many cells it contains or its nominal rated
voltage. The chart at right is a quick reference for determining this
information.
