• In the event of a crash, you must quickly and safely disconnect and remove the battery from the
model, then place it in a safe, open area away from flammable materials to observe it for at least
15 minutes.
• Store the battery at room temperature and approximately ½ charge (3.8V per cell; 11.4V for a
3S battery pack) for best results.
• When transporting or temporarily storing the battery, the temperature range should be from
40–120 degrees Fahrenheit. Do not store the battery or model in a car or direct sunlight
whenever possible. If stored in a hot car, the battery can be damaged or even catch fire.
• Do not over-discharge the battery. Discharging the battery too low can cause damage to the
battery resulting in reduced performance and duration.
Li-Po cells should not be discharged to below 3V each under load. In the case of the 3S 11.1V
Li-Po battery used for the Blade 400 3D, you will not want the voltage of the battery to fall
below 9V during flight.
The 25-amp brushless ESC installed on your Blade 400 model features a “soft” low voltage cutoff
(LVC) that occurs when the battery reaches 9V under load. When the soft cut-off occurs, the ESC
will automatically reduce power to the motor (regardless of the power level you have set with the
throttle stick/curve) in order to prevent the voltage of the battery from dropping to below 9V. After
the power is reduced and the voltage “rebounds” (rises) to above 9V, the ESC will automatically
return power to the motor until the battery reaches 9V again. This process will continue to repeat,
sometimes causing the motor/power to “pulse” rapidly, helping to provide a visual and/or audible
indication of the low battery voltage. However, in some cases it may be difficult to detect pulsing
of the motor/power, so we suggest that you be extremely aware of the power level of the Li-Po
battery during flight. If at any time the helicopter begins to require more throttle than typical to
maintain hover or flight, or has lost significant power, you must land the helicopter IMMEDIATELY
to prevent a sudden loss in power that could result in a crash.
Although the soft LVC of the ESC will help to prevent “deep” (below 9V; 3V per cell) over-
discharge of the battery, it is not recommended that you continue to run the motor for an extended
length of time after landing and/or noticing a loss of power. Routinely discharging the battery
to 9V can still cause permanent damage to the battery, resulting in shortened flight times, loss of
power output or failure of the battery entirely. It is recommended that you use the timer function of
the DX6i transmitter to keep the duration of each flight consistent and to prevent reaching the soft
LVC each time you fly.
Note: The timer of the DX6i transmitter included with your Blade 400 3D model has been
set for 4 minutes and 30 seconds. Although it is possible to achieve longer flight durations
safely depending on the performance of the battery, flying style of the pilot and other
factors, we suggest using this timer setting for the first few flights. You can keep track of the
flight duration on subsequent flights and adjust the setting of the timer, as you prefer. Please
see the manual for the DX6i transmitter for more information regarding the timer function.
If you have any further questions or concerns regarding the handling, charging and/or use of the
included Li-Po battery pack, please contact Horizon Hobby’s Product Support staff

Battery Charging
It is important that you only charge the included 3S 11.1V 1800mAh Li-Po Battery (EFLB18003S)
with the included 3S 11.1V 1.8-Amp Li-Po Balancing Charger (EFLC3115). Your battery is equipped
with special Charge Protection Circuitry and Balance Charge Leads with connector that are only
compatible with this charger. Attempting to charge the battery 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 1.8-Amp Li-Po Balancing Charger will charge a near fully discharged (not
over-discharged) 3S 11.1V 1800mAh Li-Po battery 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 battery after a
flight. NEVER charge the battery unattended.
Note: The Li-Po battery included with your Blade 400 3D will arrive partially charged. For this
reason the initial charge may only take approximately 30–50 minutes.
The charger requires up to 3-Amps of 11.5–15 Volt DC input power that can be supplied by the
optional AC to 12V DC, 3-Amp Power Supply (EFLC4030) 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.
