BATTERY CHARGING PRECAUTIONS AND GUIDELINES
LiPo batteries are dier from conventional batteries in that their chemical contents are encased in a relatively
insubstantial foil packaging. This has the advantage of signicantly reducing their weight, but does make them
more susceptible to damage if roughly or inappropriately handled. As with all batteries, there is a risk of re or
explosion if safety practices are ignored:
• Charge and store LiPo batteries in a location where a battery re or explosion (including smoke hazard) will
not endanger life or property.
• Keep LiPo batteries away from children and animals.
• Consider how you would deal with a LiPo battery re/explosion as part of your normal home Fire Safety &
Evacuation Planning.
• Never charge the LiPo battery that has ballooned or swelled due to over-/under-charging or from a crash.
• Never charge the LiPo battery that has been punctured or damaged in a crash (After a crash, inspect the
battery pack for the sign of damage. Discard in accordance with your country’s recycling laws.).
• Never charge the LiPo battery in a moving vehicle.
• Never over charge the LiPo battery.
• Never leave the LiPo battery unattended during recharging.
• Do not charge LiPo batteries near ammable materials or liquids.
• Ensure that charging leads are connected correctly. Reverse polarity charging can lead to battery damage or
a re or explosion.
• Have a suitable re extinguisher(electrical type) OR a large bucket of dry sand near the charging area . Do
not try to extinguish electrical (LiPo) battery res with water.
• Reduce risks from re/explosion by storing and charging LiPo batteries inside a suitable container: a LiPo
Sack or metal/ceramic container is advised.
• Monitor recharging LiPo batteries for signs of overheating.
• Protect your LiPo battery from accidental damage during storage and transportation. (Do not put battery
packs in pockets or bags where they can short circuit or can come into contact with sharp or metallic
objects.)
• If your LiPo battery is subjected to a shock (such as a helicopter crash) you should place it in a metal
container and observe for signs of swelling or heating for at least 30 minutes.
• Do not attempt to disassemble or modify or repair the LiPo battery.
PREVENT MOISTURE
• R/C models are composed of many precision electrical components.
• Store the battery and model in a dry area at room temperature. Exposure to water or moisture may cause
the model to malfunction resulting in loss of responsiveness, or a crash.
PROPER OPERATION
• For the safety purpose, please only use hubsan’s spare parts for replacement.
ALWAYS BE AWARE OF THE ROTATING BLADES
• When in operation, the main and tail rotor blades will be spinning at high speed. The blades are capable of
inicting serious body injury and damage to the environment.
