Low Voltage Cutoff (LVC)

Battery Installation

Battery Selection

•  We recommend the E-fl ite 2800mAh 14.8V 4S 30C Li-Po battery 

(EFLB28004S30). Refer to the Optional Parts List for other E-fl ite batteries.  
If using a battery other than those listed, the battery should be within the 
range of capacity, dimensions and weight of the E-fl ite Li-Po battery packs 
to fi t in the fuselage. Be sure the model balances at the recommended CG.

1.   Carefully lift the rear edge of the battery hatch, then pull the hatch up and 

back from the fuselage.

2.   Apply hook and loop tape to the bottom of your battery.

3.   For the recommended CG, install the battery in the middle of the compart-

ment, then press the battery onto the hook and loop strip. Close the 3 hook 
and loop straps around the battery. 

See the Adjusting the Center of Gravity 

instructions for more information.

4.   Connect a fully charged battery to the ESC. 

See the Arming the ESC instruc-

tions for correct connection of the battery to the ESC.

5.   Reinstall the battery hatch.

Tip: 

The ESC switch in the front left corner of the battery compart-

ment must be powered on for Arming the ESC.

When a Li-Po battery is discharged below 3V per cell, it will not hold a charge. 
The ESC protects the fl ight battery from over-discharge using Low Voltage Cut-
off (LVC). Before the battery charge decreases too much, LVC removes power 
supplied to the motor. Power to the motor pulses, showing that some battery 
power is reserved for fl ight control and safe landing. When the motor pulses, 
land the aircraft immediately and recharge the fl ight battery.

Disconnect and remove the Li-Po battery from the aircraft after use to prevent 
trickle discharge. Charge your Li-Po battery to about half capacity before stor-
age. During storage, make sure the battery charge does not fall below 3V per 
cell. 

 

TIP: 

Monitor your aircraft battery’s voltage before and after fl ying by 

using a Li-Po Cell Voltage Checker (EFLA111, sold separately).
