Battery Charging - E-flight Blade SR RTF Airframe Instruction Manual

Battery Charging

It is important that you only charge the included 3S 11.1V 1000mAh Li-Po Battery Pack (EFLB0997) with the included
3S 11.1V Li-Po Balancing Charger (EFLC3105). Your battery pack is equipped with special Charge Protection Circuitry
and a Balance Charge Lead with connector that is only compatible with this charger. Attempting to charge the pack
using another Li-Po charger or non Li-Po compatible charger could result in serious damage. Please familiarize yourself
thoroughly with the Battery Warnings and Guidelines section before continuing.
The included 3S 11.1V Li-Po Balancing Charger will charge a near fully discharged (not over-discharged) 3S 11.1V
1000mAh Li-Po Battery Pack in approximately 1.2–1.5 hours. In some cases the charge time may be shorter
depending on the actual amount of capacity left in the pack after a flight. NEVER charge the battery unattended.
Note: The Li-Po battery pack included with your Blade SR will arrive partially charged. For this reason the initial
charge may only take approximately 30–50 minutes.
The charger requires up to 1.5 amps of 11.5–15-volt DC input power that can be supplied by the included AC to 12V
DC, 1.5-amp Power Supply (EFLC4000) for convenient charging anywhere an AC outlet is available. NEVER attempt to
power the charger from an AC outlet without the use of a proper AC to DC adapter/power supply.
Note: When using the AC to DC adapter/power supply, the charger is protected to prevent damage if the
alligator clips touch. However, please take care to ensure that the alligator clips do not cause shorting of
the battery, adapter/power supply, etc. by keeping them clear.

Input power for the charger can also be supplied from a small 12-volt gel cell or car battery.
The charger is equipped with two LED indicators marked RED and GREEN on the label. These LEDs indicate the
following (also found on the label of the charger):
• Red Flashing LED Only: Input power with no battery connected
• Red and Green Solid LED: Battery connected and charging
• Red Solid LED Only: Charge complete
• Red and Green Flashing LED: Charge error
Once you have connected the charger to a power source (use care to ensuring proper polarity when connecting the
charger to the power source), its red LED flashes to indicate the charger has power and is ready to begin charging.
Connect the Li-Po battery pack to the charger using the specially marked Balance Charge Lead exiting the battery pack
and the connector labeled with 11.1V on the charger. The connector is keyed to prevent reverse polarity connection.
When the battery is properly connected and charging normally, the red and green LED indicators will glow solid. Once
the battery has been fully charged, the green LED will go out, leaving just the red LED glowing solid. The battery can
now be removed from the charger and installed into the Blade SR for flight.
