LiPo cells should not be discharged to less than 3V each under load. 

In the case of the 1S LiPo battery used for the Blade

®

 mCX, you will 

not want to allow the battery to fall to below 3V during flight.

The Blade mCX’s 5-in-1 control unit features a soft low voltage 

cutoff (LVC) that occurs when the battery reaches 3V under load.  

When the soft cutoff occurs, the ESCs of the 5-in-1 unit will reduce 

power to the motors (regardless of the power level you have set with 

the throttle stick) in order to prevent the voltage of the battery from 

dropping below 3V.  This reduction in power usually requires that 

you land the model immediately, at which point you should power 

down the model and unplug the flight battery. 

And while it is possible to power the model up and to fly again 

after the soft LVC occurs, this is NOT recommended as continued 

discharging to the soft LVC will cause permanent damage to the 

LiPo battery that results in lost power and duration when using 

the battery for subsequent fights, or failure of the battery entirely.  

Continued attempts to further discharge the battery may also result 

in loss of control while the motors are running as the voltage of 

the battery may drop below the minimum operating voltage of the 

receiver and other electronics.

Also, it is not recommended that you fly to the soft LVC every 

time you fly.  Instead, you should be aware of the power level of 

the battery/helicopter throughout the flight, and if at any time the 

helicopter begins to require more throttle than typical to maintain 

hover or flight, you should land the helicopter immediately.  

Routinely discharging the battery to the soft LVC can still cause 

permanent damage to the battery.

Note: When the battery power/voltage is getting low you will typically find 

that significant rudder trim and/or rudder stick adjustments are needed 

to prevent the helicopter from spinning.  This usually occurs before soft 

LVC, and indicates a good time to stop flying.

If you have any further questions or concerns regarding the handling, 

charging and/or use of the included LiPo battery pack, please contact the 

Horizon Support Team at 877-504-0233.

unused condition to the place of purchase immediately.

• You must charge the included 1S 3.7V 110mAh LiPo battery in a safe 

area away from flammable materials.

• Never charge the battery unattended. When charging the battery you  

should always remain in constant observation to monitor the charging  

process and react to potential problems that may occur.

• After flight, the battery must be cooled to ambient temperature before  

charging.

•  You MUST use the included 1S 3.7V DC LiPo Charger (EFLC1003) 

 

ONLY. Failure to do so may result in a fire causing personal injury 

 

and/or property damage. DO NOT use a NiCd or NiMH charger.

•  If at any time during the charge or discharge process the battery 

begins to balloon or swell, discontinue charging or discharging 

immediately. Quickly and safely disconnect the battery, then place 

it in a safe, open area away from flammable materials to observe 

it for at least 15 minutes. Continuing to charge or discharge a 

battery that has begun to balloon or swell can result in a fire. A 

battery that has ballooned or swollen even a small amount must 

be removed from service completely.

• Store the battery at room temperature in a dry area 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 LiPo flight battery. Discharging the 

battery too low can cause damage to the battery resulting in 

reduced power, duration or failure of the battery entirely.
