Battery information
Although batteries and rechargeable batteries are very useful in our everyday life, nevertheless they present numerous safety hazards. Therefore, always observe the following general information and safety instructions when handling batteries and rechargeable batteries.

General information

• Keep batteries/rechargeable batteries out of reach of children.
• Do not leave batteries/rechargeable batteries lying around, as they present a choking hazard for children and pets. Seek immediate medical advice if a battery is swallowed!
• Batteries/rechargeable batteries must never be shortcircuited , disassembled or thrown into fi fire. This may cause an explosion!
• When handling leaking or damaged batteries/rechargeable batteries, always use suitable protective gloves to avoid burning your skin.
• Liquids leaking from batteries/rechargeable batteries are chemically highly aggressive. Objects or surfaces coming into contact with these liquids could be severely damaged. Therefore, keep batteries/rechargeable batteries in a suitable location.
• Do not attempt to recharge disposable, non-rechargeable batteries. This may cause a fi fire or explosion! Only charge rechargeable batteries which are intended for this purpose (1.2 V); use suitable battery chargers. Batteries (1.5 V) are designed to be used once and must be disposed of
• properly when they are empty.
• Please observe the correct polarity when inserting batteries or connecting the rechargeable battery pack (observe positive/+ and negative/-). Incorrect polarity will not only damage the transmitter, model and rechargeable batteries. It may also cause a fi re or explosion.
• If you do not plan to use the model for an extended period (e.g. during storage), remove the batterie from the remote control to prevent them from leaking and causing damage. First disconnect and then remove the fl flight battery from the model. Store batteries and the fl flight battery in a dry, clean, cool place out of the reach of children.
• After use, unplug the fl flight battery and take it out of the model. Do not leave the flight battery in the model when you are not using it (e.g. during transport or storage). Otherwise, this may cause deep discharge or permanent damage to the fl ight battery.
• Never charge the helicopter battery immediately after use. Always allow the fl ight battery to cool down until it has reached room or ambient temperature again.

Additional information about lithium rechargeable batteries

Modern lithium rechargeable batteries are much more powerful and signifi cantly lighter than NiMH rechargeable batteries. This makes lithium rechargeable batteries (especially lithium polymer batteries) particularly suitable for use in model making. However, lithium rechargeable batteries require particular care to ensure safe charging/discharging, operation and handling. The following section provides an overview of the potential hazards associated with lithium rechargeable batteries and explains how these hazards can be avoided to ensure a long lifespan.

• The casing of many lithium rechargeable batteries is made of a thick fi film, which is very sensitive. Do not dismantle, damage, drop or insert any objects into lithium rechargeable batteries! Do not apply mechanical loads or pull on the rechargeable battery’s connection cables. This maycause a fi re or explosion!
• Ensure that the rechargeable battery does not overheat during use, recharging, discharging, transport or storage. Do not place the rechargeable battery next to sources of heat (e.g. a speed controller or motor) The temperature of the rechargeable battery must not exceed +60 °C. (If necessary follow additional manufacturer specifi cations for the rechargeable battery!).
• Use special carry bags to carry LiPo rechargeable batteries, which can lessen the consequences of a sudden fi re or explosion.
• If there are any signs of damage or the outer casing starts to swell or bloat, discontinue use immediately.
