output reverse polarity and open circuit errors
• Very small and lightweight for portability
• Charge only lithium-polymer (Li-Po) rechargeable
batteries. Do NOT attempt to charge other types of
rechargeable batteries as permanent damage to
the battery and charger could result.
• Do not leave the charger unattended while
charging. Disconnect the battery and
remove input power from charger
immediately if it becomes hot!! Allow the
charger to cool down before reconnecting.
• Disconnect the battery from the charger
immediately if the battery begins to swell
or smoke!!
• 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 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 place the charger or any battery on a
flammable surface or near a combustible
material while in use. Do not charge or
discharge on a carpet, cluttered workbench,
paper, plastic, vinyl, leather, and wood, inside
an R/C model or full-sized automobile!
• Always disconnect from input power when not
in use.
• Do not overcharge batteries as permanent
damage could result. Do not use a charge
current rate which exceeds the safe level of the
battery. Do not attempt to charge a battery if it
is swollen or hot.
• Keep out of reach of children.
IMPORTANT!! Lithium-polymer batteries are a
revolutionary new rechargeable battery
technology for electric R/C flight, offering a
variety of significant advantages over NiCd,
NiMH and Li-Ion batteries. It is very important
to have a good understanding of the operating
characteristics of Li-Po batteries – especially
their exact rated voltage and maximum
acceptable charge current. Always read the
specifications printed on the label of your
Li-Po battery prior to use, and read this
instruction sheet in its entirety.
WARNING! Lithium-Polymer batteries are ENTIRELY
DIFFERENT than NiCd and NiMH batteries and must
be handled differently as well!! Great Planes will not
be held responsible for any and all incidental
damages and bodily harm that may result from
improper use of ElectriFly
™ brand lithium-polymer
batteries. Failure to follow the care and handling
instructions can quickly result in severe, permanent
damage to the batteries and its surroundings and
even start a FIRE!
IMMEDIATELY remove a Li-Po battery from a
model if it is involved in a crash in any way.
Carefully inspect the battery for even the smallest
of dents, cracks, splits, punctures or damage to the
wiring and connectors. CAUTION! Cells may be
hot! DO NOT allow the battery’s internal electrolyte
to get in the eyes or on skin – wash affected areas
immediately if they come in contact with the
electrolyte. A Li-Po battery might not appear to be
damaged after a crash, but it could smolder over a
short amount of time and suddenly catch fire
unexpectedly. If in doubt, place the battery in a
Fireproof location indefinitely.
The PolyCharge Li-Po Battery Charger only
accepts DC input power which could come from a
power supply or 12V automotive battery. Do not
attempt to apply more than 15V to the input, as
permanent damage to the charger could result and
void the warranty. Applying less than 11V to the
inputs will not be sufficient power to allow the
charger to work properly. Securely connect the
charger’s red alligator clip to the positive (+)
terminal on the power source, and the black
alligator clip to the negative (-) terminal. It’s best to
use a clean DC power source whose output is
filtered to remove unwanted electrical noise. To
achieve maximum potential, the power source
must be capable of delivering at least 2.0 amps of
current while maintaining 12 volts DC. Disconnect
the charger when not in use.
WARNING! Make sure the charger’s positive (+)
and negative (-) input connections are never
accidentally shorted together when connected
to 12V DC power. Failure to do so could result
in permanent damage to the power source and
the charger.
Input Power and Connector: Connect the
charger to the desired power source using the
alligator clips on the input lead as described
above. There is no on/off power switch on this
charger. Therefore, once connected to input power
the charger is active and in “idle mode,” ready to be
connected to a battery. The bright blue LED will
flash once every 3 seconds and the buzzer will
beep briefly to indicate that power is applied.
Output Connector: The PolyCharge Li-Po Battery
Charger is equipped with a red 2-pin battery
connector on the output. Securely connect the
battery to be charged to the output connector. Pay
special attention to ensure that the desired battery
polarities are the same as the charger. The battery’s
positive (+) battery lead (red) connects to the
charger’s red wire, and the battery’s negative lead
connects to the charger’s black wire. It is highly
recommended to use pre-assembled battery leads
to avoid possible erroneous operation as a result of
using poor quality connections.
WARNING! Do not short the battery
connections, as permanent damage to the
battery and/or the charger could result and
void your warranty.
Controls: The PolyCharge Li-Po Battery Charger
includes one charge current selection switch which
determines how much current should be delivered
to the battery during charge. Again, there is no
on/off power switch. And, there is no button or

SPECIAL FEATURES
SPECIFICATIONS
The PolyCharge ™ Lithium-Polymer Battery Charger is great for simple, precise charging of lithium-polymer batteries for small electric aircraft at the flight line.
Capable of charging 1 to 3 cell Li-Po batteries with three charge current rates of 250mA, 500mA and 1000mA, this small, lightweight charger is good for entry-
level uses. Do NOT attempt to use this charger with NiCd, NiMH or Lithium-Ion batteries as they are not compatible! Read this entire instruction sheet
to learn about specific functions and features, and safety information. Damage resulting from misuse or modification of this charger will void your
warranty.
