BLH7600 Nano QX Quadcopter Manual

Low Voltage Cuto (LVC)

When a Li-Po battery is discharged below 3V, the battery may become damaged and may no longer accept a charge. The

nano QX 4-in-1 control unit protects the ﬂ ight battery from over-discharge using Low Voltage Cutoff (LVC). Before the bat-

tery charge decreases too much, LVC becomes active. Power to the motors decrease and the LED on the 4-in-1 control

unit blinks, showing some battery power is reserved for ﬂ ight control and safe landing.

When the motor power decreases, please 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. During storage, make

sure the battery charge does not fall below 3V.

NOTICE: Repeated ﬂ ying to LVC will damage the battery.

Installing the Transmitter Batteries (RTF)

Install 4 AA batteries into the transmitter, noting polarity. Replace the

transmitter batteries when the power LED ﬂ ashes and the transmitter

beeps.

Battery Charging

Your aircraft comes with a 1S 3.7V DC Li-Po battery

charger and 1S 3.7V 150mAh 25C Li-Po battery.

Refer to the charging warnings. It is recommended

to charge the battery pack while you are inspecting

the aircraft. The ﬂ ight battery will be required to

conﬁ rm proper aircraft operation in future steps.

NOTICE: Charge only batteries that are cool to the touch and are not damaged. Look at the battery to make sure it is not

damaged e.g., swollen, bent, broken or punctured.

1. Insert the charger into a USB port. The charger only uses power from the USB port, it will not connect to your computer.

USB power supplies, such as those used to charge cellular phones, can also be used.

2. Slide the battery into the slot on the charger and press it into the charge jack/connector located at the bottom of the slot.

The end cap of the battery is speciﬁ cally designed to allow the battery to ﬁ t into the slot one way (usually with the label

on the battery facing outward) to prevent reverse polarity connection. However, check for proper alignment and polarity.
