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 de 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 = 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.

A. OUTPUT BANANA JACKS
For connection to a wide variety of charge adapters.
Adapters with a standard plug and Star Plug are included.
For small electric vehicle batteries, nd a charge lead that
best matches the type of battery you are charging. Look
for these and other charge adapters at your local retailer:
Item Number Charge Lead Description
DTXC2220 Charge Lead – banana plugs to standard
DTXC2223 Charge Lead – banana plugs to mini plug
DTXC2224 Charge Lead – banana plugs to XT90
DTXC2225 Charge/Balance Lead – 4mm Bullet
Always connect the charge lead to the charger rst. Then
connect the battery to the charge lead. Always match
polarities on the battery wires, charge leads and banana
jacks – black connection to black (-) and red connections
to red (+).
B. BALANCE PORT
To connect an adapter for balancing of lithium batteries.
See page 9.
C. RADIO BATTERY
To directly connect a receiver or transmitter battery for
charging.
INPUT POWER
AC Input: For indoor use, this charger includes a builtin 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 left side of the charger
is a jack for the connection of the DC power cord. Once
5
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.
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.
COOLING FAN
A built-in cooling fan helps keep the charger cool during
operation. This will help extend the service life of the charger,
and allow it to function more accurately and ef ciently. The
fan only functions while a battery is being charged.
CAUTION: Place the charger on a at surface. Do not
block the vent holes for the cooling fan on the bottom
of the charger. Failure to do so could cause the charger
to overheat and possibly cause permanent damage.
DETERMINING BATTERY TYPE & SPECIFICATIONS
IMPORTANT: What is your battery’s CHEMISTRY TYPE,
RATED CAPACITY, AND RATED VOLTAGE? To avoid
causing permanent damage to your battery, carefully read
your battery’s label and/or instruction sheet or consult your
battery supplier and determine:
1. TYPE: Is the battery a nickel-metal hydride (NiMH),
nickel-cadmium (NiCd), lithium-polymer (LiPo), lithium-ion (LiIon), or lithium-ferrite-phosphate (LiFe, such
as LiFeSource brand)?
2. RATED CAPACITY: The amount of charge energy the
battery can store should be listed on the battery’s label
in “mAh” (“milli-amp hours”).
3. RATED VOLTAGE: If not printed on the battery’s label,
consult your battery supplier or determine the proper
pack voltage as follows (refer to the charts at right):
a. NiMH and NiCd: number of cells 1.20.
b. LiPo batteries: number of cells 3.70.
c. LiIon batteries: number of cells 3.60.
d. LiFe batteries (LiFeSource): number of cells 3.30.
