Safety Precautions
Lithium Polymer batteries are volatile. Failure to read and follow
these instructions and safety precautions may result in fire,
personal injury and damage to property if batteries are charged
or used improperly. Horizon Hobby, Inc. and its retailers assume
no liability for failures to comply with these instructions and
precautions.
• Do not leave the battery and charger unattended while in
use.
Improper charging of Li-Po batteries could
result in fire.
• When charging, constantly monitor the temperature of
the battery pack. If the battery becomes hot to the touch,
discontinue the charging operation immediately by
disconnecting the battery pack.
• Never charge around or in the area of any flammable or
combustible materials. The safest place to charge is on
a concrete surface.
• Do not allow children to charge battery packs unless
supervised by a responsible adult.
• The charger can become hot during charging. Use care
when selecting where you will charge the battery packs.
• This charger is DC only. Please note (+) (-) cannot be
connected inversely.
• The charger will not operate if the supply voltage is
below 10V.
• This charger is designed for lithium-polymer batteries
only. It MUST NOT be used to charge Ni-Cd and Ni-MH
battery packs.
• Maximum charging rate of the Li-Po battery should
not be set to over 1x capacity. Ideal charge rate is
approximately .7x the capacity of the pack.
• Please check power source or output to make sure they
are connected properly. The charger will not operate if
either is connected incorrectly.
• If at any time you see a battery starting to balloon or swell
up, discontinue charging process immediately. Batteries
in this condition may leak, and the reaction with air may
cause the chemicals to ignite, resulting in fire. Disconnect
the battery from the charger and observe it in a safe place
for approximately 15 minutes.
• Let the battery cool down to ambient temperature
before charging.
• Do not charge battery packs in series. Charge each
battery pack individually. Failure to do so may result in
incorrect battery recognition and charging functions.
Overcharging may occur and fire may be the result.
Supplying DC Power to the Charger
The charger is powered by connecting it to a 12V power source,
such as a 12V sealed battery (HAN102), a 12V automobile
battery (car must be not be running), a field box power panel
or appropriate power supply. The battery capacity must be
over 5Ah.
The charger includes two different methods of connecting the
charger to your power supply. Use the option best suited for
your application.
• Banana connectors for use with most power supplies
• Alligator sleeves for use with 12V sealed batteries,
automobile batteries
Step 1: Attach the red (positive) banana plug to the red (positive)
terminal on your 12V battery or power panel. Attach the black
(negative) banana plug to the black (negative) terminal on your
12V battery or power panel.
Step 2: Slide the alligator sleeves onto the banana connectors.
Attach the black (negative) banana plug to the black (negative)
alligator clip, and red (positive) banana plug to the black
(negative) alligator clip. Attach the red (positive) alligator clip to
the red (positive) terminal on your 12V battery or power panel,
and the black (negative) clip to the black (negative) terminal.
Once your charger is given power, the 6 control LED’s will blink
in order from 2000mA to 2-cell. After a signal tone, the 2-cell
and 500mA LED’s will light solid.
