Hubsan X4 FPV Quick Manual

Lithium-ion batteries are the only source of power for consumer drones. Using and Maintaining drone batteries
properly is important to ensure drone flight safety, and safety of users and others.
Understanding Battery Cells Voltage:
Drones use Lithium battery cells. A single cell voltage 3.8V is the rated operating voltage. The actual voltage of
a lithium battery cell is 2.75v Min to 4.375V Max when fully charged. The capacity marked on the lithium battery
is the amount of electricity obtained by discharging from 4.35V to 2.75V.
Charging the batteries:
Never leave drone batteries charging unattended:
Charging a drone battery is most important. Charging is the most likely time for a drone battery to catch

fire, so concentrate the bulk of your safety efforts there. According to the CPSC, more than half of the
drone-battery incidents documented at hospital emergency rooms occurred while the drone was charging.
If you can, charge your batteries outdoors. the single safest way to charge a drone battery is to do it

outdoors. That's the only place you can be sure it isn't near anything else that can catch fire. An exploding
battery also gives off toxic gases, which can be dangerous in an enclosed space. Just be sure to keep the
batteries out of the sun so they don't overheat, and away from dried-out plants or other combustibles.
If you have to charge indoors, set up fire-containment measures just in case. You can charge batteries

inside cinder blocks, use ammo boxes and or just get yourself an old Microwave oven and use it as a safe
box to charge and or store your batteries inside. and keep a bucket of sand nearby to extinguish flames. If
you must charge indoors and you choose one of these methods, make sure the setup isn't near anything
else that can catch fire. Never seal a battery inside a fireproof container. all that energy needs to go
somewhere, and sealing it off will just cause the container to explode. That's why good fire containment
focuses on aiming flames and gases in a safe direction and then getting sand or water on it as fast as
possible.
Warning! Over Charging the Battery:
Always use supplied and dedicated Hubsan Drone Battery Chargers. These chargers are specially

designed to charge your drone batteries safely and balance each cells properly. Also they have safety
voltage cut off, and power cut off features once a battery is fully charged.
