Battery Safety

Lithium-Polymer batteries are a revolution in battery technology. These next-generation batteries
are capable of powering the Draganflyer in ways that would have been unimaginable only a year
ago. However, Lithium-Polymer batteries require special consideration and handling techniques due
to their extremely high capacity.

Use only chargers designed specifically for Lithium-Polymer batteries
Use only Draganfly Lithium-Polymer batteries with your Draganflyer V Ti and charger
Never allow the battery to short circuit
Do not leave Lithium-Polymer batteries charging unattended
Do not charge batteries near flammable materials
Do not store Lithium-Polymer batteries inside of your vehicle. Temperatures inside a parked
vehicle can rapidly exceed the recommended maximums.
Do not allow the battery temperature to exceed 160 degrees Fahrenheit. Permanent damage
will result.
Do not allow the battery to discharge below 9 volts, this will permanently damage
the battery.

After a serious crash, visually monitor the Lithium-Polymer battery for swelling or overheating on
a fire-proof surface(ie, concrete) to ensure it has not sustained any internal damage.

If the Lithium-Polymer battery is damaged in a crash or appears to swell, discontinue use
immediately, place the battery away from anything flammable (ie bare concrete floor), and
contact Draganfly Innovations technical support for assistance.

1.  Read Draganflyer V Ti Lithium-Polymer Battery Precautions before charging or using batteries.

2) When the battery voltage begins to drop the helicopter enters a forced landing condition.All of

the controls will be the same except the maximum allowable throttle will be slowly reduced. In
this mode all of the  led 'eyes' will blink together. Land and recharge the battery. Attempting to
fly past this past this point will permanently damage the battery.

3) Allow the Draganflyer V Ti motors to cool after every 6-9 minutes of flight. Extended continu-

ous operation of the Draganflyer V Ti (especially when performing advanced maneuvers) will
result in overheating of the motors and possibly shorten their life. This will also allow the battery
to cool, resulting in longer flight times and longer overall life for the batteries.

4) Allow the battery to cool to room temperature after use and before charging as well as after

charge and before use in the Draganflyer V Ti.

5) If you notice a performance decrease of greater than 20% in your Lithium-Polymer battery, the

battery is at the end of its life cycle. Do not continue to use, and ensure the battery is disposed of
properly. Repeated continuous operation of the Draganflyer V Ti without allowing appropriate
time for the motors to cool will result in premature wear and shortened life for the motors.

Replacement motors are available.
