IMPORTANT PRECAUTIONS
●Charge only lithium-polymer (LiPo) rechargeable
batteries that are 2S (2 cells in series) 7.4V nominal
voltage, from 150 mAh to 750 mAh, which have a
balance connector.
●Do not attempt to use this charger with NiCd, NiMH or
different types of Lithium-Ion batteries as they are not
compatible!
●Do not leave the charger unattended while charging.
Disconnect the battery and remove input power from
charger immediately if either becomes hot! However, it
is normal for the charger to get warm.
●Disconnect the battery from the charger immediately
and remove to a fireproof location if the battery begins
to swell or smoke!
●Only use the included car adapter or approved AC
adapter to power the charger.
●Do not use charger with car running.
●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 place the charger or any battery on a flammable
surface or near a combustible material while in use.
●Do not charge on a carpet, cluttered workbench, paper,
plastic, vinyl, leather, wood, or inside an R/C model.
●Never charge inside a full-sized vehicle.
●Always disconnect charger from input power when not
in use.
●Do not attempt to charge a battery if it is swollen or hot.
●Keep out of reach of children.
CHARGING BATTERIES
IMPORTANT!! ALWAYS charge a LiPo battery in a
location that is fireproof. NEVER leave the battery
unattended while being charged! If the battery feels
warm during charge, remove the battery at once and
disconnect the charger from the power source.
Heat-resistant LiPo charging bags (GPMP0751) provide
additional safety when charging and are available
through your hobby supplier.
Use only approved power input accessories – the
included car adapter and AC adapter (also available
separately GPMM3310).
To charge a battery:
1. Connect input power to
the charger. The GREEN
LED will be lit, indicating
standby mode. The RED
LED will be OFF.
2. Connect the battery to
be charged to the balance
plug. The RED LED will also be lit, and remain RED during
charging. Both LEDs should be lit solid while charging.
The ElectriFly
®
LiPo Battery Charger is great for simple balance
charging of 2-cell lithium-polymer batteries for small electric
models. Use it only to charge batteries within a capacity range
of 150 to 750mAh.

3. When the battery is fully charged, the GREEN LED will turn
OFF. Remove the battery from the charger at this time.
4. Charging time depends on level of discharge and capacity
of the battery. To estimate how long it should take to charge an
empty battery, divide the capacity of the battery in mAh by the
charge rate in milliamps:
200 mAh battery / 450 mA ~ 30 minutes
350 mAh battery / 450 mA ~ 50 minutes

Flashing Flashing ERROR
Possible sources of battery error may include a highly unbalanced
pack, charger timed out, or one cell in the pack which is low
voltage. In the case of a battery error, please remove the battery
pack from the charger and inspect it carefully for swelling or any
other damage, such as broken wires.

ONLY use a LiPo approved charger. NEVER use a NiCd/
NiMH peak charger to charge a LiPo battery.
NEVER charge in excess of 4.20V per cell.
ONLY charge through the “charge” lead. NEVER charge
through the “discharge” lead.
NEVER charge at currents greater than 1C unless the
battery is rated for a higher charge rate.
ALWAYS set the charger’s output volts to match the
battery volts.
ALWAYS charge in a fireproof location.
NEVER trickle charge.
NEVER allow the battery temperature to exceed 150
degrees F (65 degrees C).
NEVER disassemble or modify the pack wiring in any way
or puncture the cells.
NEVER discharge below 2.5V per cell.
NEVER place the battery or charger on combustible
materials or leave it unattended during charge or discharge.
ALWAYS KEEP OUT OF THE REACH OF CHILDREN.
NEVER charge the battery in the plane.
ALWAYS remove the battery from the plane after a crash.
Set it aside in a safe location for at least 20 minutes. If
the battery is damaged in the crash it could catch fire.
If the battery starts to swell, quickly move the battery to
a safe location, preferably outside. Place it in a bucket,
covering the battery with sand. Never use water to try and
put out a LiPo fire.
