B) Additional Information About Lithium Rechargeable Batteries - Reely Black Rocket X V2 Bedienungsanleitung

• Disconnect the drive battery from the model before connecting it to the charger. Never leave the battery
connected to a speed controller when it is charging. This may damage the charger, speed controller or
the battery! Always remove the drive battery from the model before charging it.
• Place the charger and drive battery on a non-flammable, heat-resistant surface (e.g. stone tiles). Keep
the charger and drive battery away from flammable objects. Maintain a sufficient distance between the
charger and the drive battery. Never place the drive battery on top of the charger.
• Do not charge batteries when they are still hot (e.g. due to a high discharge current in the model). Allow
the battery to cool down to room temperature before charging it.
• Ensure that there is sufficient ventilation, as the drive battery and charger may heat up during the charg-
ing process. Never cover the charger and the drive battery!
• Never leave rechargeable batteries unattended when they are charging. Inspect the charger at regular
intervals to ensure that the rechargeable battery is not overheating or expanding. This indicates an
imminent risk of fire or explosion! If the battery overheats or starts to expand, disconnect it from the
charger immediately and take it to a location where it will not cause any additional damage if it explodes
or catches fire (e.g. outdoors).
• Disconnect the drive battery from the charger when it is fully charged.
• This model boat is only suitable for use with a 3-cell LiPo drive battery (nominal voltage 11.1 V).
• Never damage the casing of a rechargeable battery.
• Never charge damaged, leaking or deformed rechargeable batteries. This may cause a fire or explosion!
Discontinue use immediately and dispose of such unusable rechargeable batteries in an environmentally
friendly manner.
• Rechargeable batteries should be charged regularly (approx. once every 2–3 months) to prevent deep
discharge due to self-discharge. This may render the rechargeable batteries useless!
LiPo rechargeable batteries usually retain their charge for several months. However, deep discharge of
the batteries will result in permanent damage and render them useless.

b) Additional information about lithium rechargeable batteries

Modern lithium rechargeable batteries are much more powerful and significantly lighter than NiMH
rechargeable batteries. This makes lithium batteries (especially lithium polymer batteries) particu-
larly suitable for use in model making.
However, lithium rechargeable batteries require particular care to ensure safe charging/discharg-
ing, operation and handling.
The following section provides an overview of the potential hazards associated with lithium re-
chargeable 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 film, which is very sensitive. Do not
dismantle, damage, drop or insert any objects into lithium rechargeable batteries! Do not apply mechani-
cal loads or pull on the rechargeable battery's connection cables. This may cause a fire or explosion!
Pay attention to this when the rechargeable battery is attached to or removed from the model.
• 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)
or expose it to direct sunlight. Overheating of the rechargeable battery may cause a fire or explosion!
The temperature of the rechargeable battery must not exceed +60 °C. (If necessary follow additional
manufacturer specifications for the rechargeable battery!).
