● “Constant current/constant voltage” charge method

● Automatically starts charge upon connection of

battery to the balance plug

● 450 mA maximum charge current requires no

adjustment

● Twin LEDs indicate charging status

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 fi reproof 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

fl ammable 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 fi reproof. 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.

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

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.
