Supplying DC Power to the 1-3 cell Li-Po charger

The Celectra™ 1–3 cell Li-Po 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 power supplies
• Alligator sleeves for use with 12V sealed batteries, automobile batteries or power supplies

Step 1: Attach the red (positive) banana plug to the red (positive) terminal on your 12V power source. 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, it will beep once, and the LED will light up momentarily to indicate the charger is receiving power.

Charging Process

Step 1: Connect the battery to the charger. The charger will signal the connection of the battery by producing one long beep. The

LED will also flash once indicating the connection of the battery.

Step 2: Refer to the chart below for recommended charge rates. Select the appropriate charge rate for your particular battery.
Step 3: Select the proper number of cells that you will be charging, 1-, 2-, or 3-cells. Remember that a 1-cell pack is 3.7V, a 2-cell

pack is 7.4V, and a 3-cell pack is 11.1V. It is very important that you select the correct number of cells. Failure to comply
may result in fire.

Step 4: Attach the output charge lead to the banana plug jacks on the charger. The red (positive) banana plug lead wire plugs into the

red (positive) jack on the charger. The blacks (negative) lead plugs into the black (negative) jack on the charger.

Step 5: Plug the connector on the end of the charge lead to the LiPo battery pack. The beeper will sound once and the LED will

begin flashing.

Step 6: Push the Start button once. You will hear a short beep, and the LED will remain on continuously to indicate the

battery is charging.

Note: Do not adjust the charge rate switch in this state.

Note: This charger is designed to automatically detect cell count selection errors as an added safety feature. If the wrong

cell switch selection is chosen for a 1-, 2-, or 3-cell pack and the start button is pushed the beeper will beep twice followed

by three beeps continually. The charge function will not proceed until the correct number of cells is chosen. To correct this,

simply move the cell selection switch to the match the correct number of cells connected and the charger will automatically
commence charging. The above is true for cell selections over and under the correct cell count.

Step 7: When charging is complete, the charger will emit ten triple-beeps and then the LED will continuously flash.

Note: A few seconds prior to the end of the charge process, the LED display goes through a series of flashes, indicating the

charge cycle is nearly complete.

The charger is now in trickle charge. The beeper will sound every 45-60 seconds until the battery is disconnected. Do not leave the
battery connected to the charger when charging is complete. Failure to comply may result in fire.
Step 8: Push the Start/Select button to process any further charge function if necessary.
WARNING: SELECTING A CHARGE RATE HIGHER THAN 1X BATTERY CAPACITY MAY RESULT IN FIRE.

Forced Charging Feature

When the voltage is too low on a single cell battery, some chargers may not charge the battery because the voltage is below an
acceptable minimum voltage, thus not recognized by the charger. You can bypass this by selecting 1-cell on the charger and pushing
the START button and holding it for three seconds. The beeper will sound twice and the charger will be forced to charge for two
minutes. After two minutes, it will estimate the voltage again and begin the charging process if the voltage has been brought up to an
acceptable minimum voltage.
