IMPORTANT PRECAUTIONS
3
Disconnect the battery and remove input power from
the charger immediately if the charger becomes hot!!
Do not attempt to charge any battery types other than LiFe 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 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 specifications.
Do not leave the charger unattended while in use.
Do not place the charger or battery on flammable 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’s AC and DC input connectors to any power source at the same time.
Allow the charger or battery to cool down before reconnecting.
Always disconnect from power source when not in use.
GLOSSARY OF TERMS
4
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 x 1000). 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 200mAh battery can deliver 200mA of current for one hour (200mA x 1hr
= 200mAh). A 1900mAh battery can deliver 1900mA (1.9A) of current for one hour (1900mA x 1hr = 1900mAh), 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. An 1100mAh battery has a 1C current value of 1100mA, and a 3C current value of (3 x 1100mA)
3300mA or 3.3A. The 1C current value for a 3200mAh battery would be 3200mA (3.2A), etc.
INPUT POWER
5
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. The AC power supply has a maximum power limitation that limits
charge current to 2 amps maximum. Maximum charge current for 3S packs might be limited to approximately 1.6A.
DC Input: This charger can be powered by a portable 12V DC power source for use at the field. 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 6 amps while maintaining 12 volts DC. Larger 3S LiFe batteries
will charge more completely if the DC input voltage applied to the input is greater than 13V, otherwise an error
indication might show.
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. Do not attempt to connect the charger to AC and DC inputs at the same time.
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

WARNING! Do NOT attempt to
charge one battery through the
main output lead, and another
through the jack on the front edge of the
charger at the same time!! Doing so might
permanently damage the charger.
DETERMINING BATTERY SPECIFICATIONS
7
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.
STARTING CHARGE
8
1. Connect the charger to either AC or DC input power.
2. A tone will sound, and the charger’s green LED will flash very slowly
(once every four seconds) as a reminder that power is applied to the
charger, and it is now ready for use.
3. Select a charge current with the AMPS switch. Refer to the chart at
right for recommendations. Do not exceed the maximum rated charge current for the battery.
4. START CHARGE - Connect the battery to the charger:
A. If the 3S battery includes a balancing lead similar to as shown at right, connect it directly to the
balancing jack on the charger. If using a 2S LiFe pack, connect the battery’s balancing lead to
the supplied 2S adapter, and the adapter to the charger’s balancing jack.
B. Connect the battery’s main lead to the charger. For batteries having a Deans Ultra plug, connect
it directly to the Deans connector on the charger. For batteries that ONLY have a universal Rx
connector, connect it directly to the Rx jack on the front edge of the charger. Make sure the
battery’s black wire is on the right when inserting the radio connector into the radio jack.
IMPORTANT! For LiFeSource packs which have both Deans and universal connectors, do NOT connect
both connectors to the charger at the same time. Connect only ONE such connector to the charger.

CHARGE CURRENT RECOMMENDATIONS
Battery’s Rated Capacity Charge Current Setting

Once the battery is connected, the charger will beep and automatically detect the number of cells in the pack, and
the green LED will flash once for each cell in the pack. Fast charge will start automatically. The green LED will turn
on at this time. The cc/cv charge method will fully charge the battery.
5. When the battery has become fully charged, the red LED will flash once for each cell in the pack, with tones for 10
seconds to indicate that fast charge has ended. Low level balancing currents may be applied after fast charge ends, if
needed, until the battery is disconnected. The battery is now ready for use and can be disconnected from the charger.
To manually stop charge at any time, disconnect the battery from the charger. The green LED will flash for 3 seconds
and then return to ready mode.
A backup safety timer is built-in to automatically stop charge if the battery does not become fully charged in 90 minutes.
If the amber LED begins flashing quickly (once per second), the safety timer has stopped charge. The battery might
NOT be fully charged at this time. You could attempt to measure the voltage of the battery to determine if charge was
actually received. Refer to the Troubleshooting Guide for more details.
HEAT VENTILATION
9
Vents are built into the case to allow hot air to escape to help keep the electronic circuitry cool. This helps to maintain
accurate operation and maximize the lifespan of the charger itself. CAUTION: Do not block the vent holes during
operation, as it could cause the charger to overheat and possibly cause permanent damage.
ERROR INDICATORS AND TROUBLESHOOTING GUIDE

TROUBLESHOOTING CHART
LED ACTION PROBLEM AND SOLUTION
Amber flashes once
per 3 seconds
90 minute safety timeout occurred. Charge current setting is too low for battery.
Battery might have internal problem and require replacement.
Amber flashes twice
per 3 seconds
The battery is connected backwards. Reverse connections.
Amber flashes 3 times
per 3 seconds
The voltage on the input is out of the 11-15V range. Check the voltage on the input, and adjust
as necessary. If using DC input and charging a 3S pack, increase input to 13-15V DC.
Amber flashes 4 times
per 3 seconds
The voltage of the pack or any cell is unacceptable. Ensure the battery pack is not out of balance
before calling Product Support.
Battery connected but no LED Charger not properly connected to input power or to battery. Re-check all connections and wiring.
Or internal problem exists in charger or battery – contact Hobby Services.
Battery voltage low after
charge is completed
Make sure charge current selection isn’t too low for battery. Battery may be defective or out of
balance and require replacement. Make sure the charger’s backup safety timer hasn’t expired
before full charge ended.
