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 = 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
600 mA) 1800 mA 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
WARNING!! DO NOT try to charge lithium-polymer (LiPo) 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 fi reproof location, which could be a container made of metal or ceramic tile.
Monitor the area with a smoke or fi re alarm, and have a lithium approved fi re extinguisher available at all times.
●
ALWAYS
use a LiPo charge bag when charging LiPo batteries, such as the Great Planes
®
SafeCharge
™
LiPo
Battery Charge Bag (GPMP0751).
●
NEVER
attempt to extinguish a lithium fi re with water or a non-lithium approved fi re extinguisher! Use
ONLY
a
“Class D” fi re extinguisher.
●
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
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 batteries if the charger fails to recognize full charge. LiPo cells which swell or emit
smoke may be in an overcharge condition and should be disconnected from the charger immediately.
●
NEVER
charge LiPo batteries at currents greater than the maximum rated current as specifi ed by the battery’s
manufacturer.
●
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
immediately if they come in contact with the electrolyte and contact your physician!
●
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.

STARTING CHARGE
1. Connect the charger to either AC or DC input power.
2. The charger will beep and the orange LED will fl ash once. The
green LED will fl ash very slowly (once every four seconds) as a
reminder that power is applied to the charger, and it’s now ready
for use.
3. Select a charge current with the current selection 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.
For a 3S battery that includes a balancing lead similar to as shown at right, connect it
directly to the balancing jack on the side of the charger. If using a 2S LiPo pack, connect
the battery’s balancing lead to the supplied 2S adapter, and the adapter to the charger’s
balancing jack.
IMPORTANT! ALWAYS connect the battery’s balancing lead to the
balancing jack on the charger!
Note: For LiPo batteries that have a FlightPower
®
/ ThunderPower balance connector,
an optional adapter will be needed and is available separately (Onyx 150 ThunderPower Balance Adapter, DTXP4160).
B.
Connect the battery’s main lead to the charger’s output lead. For batteries having a Deans
®
Ultra Plug
®
, connect
it directly to the Deans connector on the charger. For batteries with a Traxxas connector, the included Deans to
Traxxas adapter will need to be connected to the charger fi rst. Then connect the battery to the adapter. For batteries
that ONLY have a universal Rx connector, connect it directly to the radio 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.
NOTE:
Both the
balance lead and the main charge lead
MUST
be connected in order to charge!
Once the battery is connected, the charger will beep and automatically detect the number of cells in the pack,
and the green LED will fl ash once for each cell in the pack. Fast charge will start automatically. The CC/CV charge
method will fully charge the battery.
5. When the battery has become fully charged, the red LED will fl ash quickly, 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 orange LED will fl ash 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 LED begins fl ashing 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.
