B) Additional Information About Lithium Rechargeable Batteries - Reely 1601093 Bedienungsanleitung

• Disconnect the boat battery from the model completely 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 battery from the model boat before recharging it.
• Place the charger and rechargeable battery on a non-flammable, heat-resistant surface (e.g. stone tiles).
Keep the charger and battery away from flammable objects. Maintain a sufficient distance between the
charger and the battery. Never place the battery on top of the charger.
• Do not charge batteries when they are still hot (e.g. due to a high discharge current in your model). Allow
the battery to cool down to room temperature before charging it.
• Ensure that there is sufficient ventilation, as the battery and charger may heat up during the charging
process. Never cover the charger or the rechargeable battery!
• Never leave batteries unattended when they are charging. Inspect the charger at regular intervals to
ensure that the battery is not overheating or expanding. If this is the case, it indicates an imminent risk
of a fire or explosion. If the battery overheats or starts to expand, disconnect it from the charger imme-
diately 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 battery from the charger when it is fully charged.
• Never damage the casing of a rechargeable battery. Never charge damaged, leaking or deformed bat-
teries. This may cause a fire or explosion! Discontinue use immediately and dispose of the battery in an
environmentally friendly manner.
• Rechargeable batteries should be charged regularly (approx. once every 2–3 months) to prevent them
from overdischarging. This may result in permanent damage and render the batteries useless.
LiPo batteries usually retain their charge for several months. However, if the batteries overdischarge, this
will result in permanent damage and render them useless.

b) Additional information about lithium rechargeable batteries

Modern lithium rechargeable batteries have a significantly higher capacity than NiMH and NiCd
batteries and are also significantly more lightweight. This makes lithium batteries (especially
Lithium Polymer batteries) particularly suitable for use in model making.
However, LiPo batteries require particular care during charge/discharge, operation and handling.
The following sections provide an overview of the potential hazards associated with LiPo batteries
and explain how these hazards can be avoided to ensure a long lifespan for such batteries.
• The casing of many lithium batteries is made of one single thick film, which is very sensitive. Do not
dismantle, drop or insert any objects into lithium batteries. Do not apply mechanical loads or pull on the
battery's connection cables. This may cause a fire or explosion!
Always observe these instructions when inserting or removing a battery from your model.
• Ensure that the battery does not overheat during use, recharging, discharging, transport or storage. Do
not place rechargeable batteries next to sources of heat (e.g. a speed controller or motor) or expose
them to direct sunlight. This may cause the battery to overheat, which can cause a fire or explosion! The
temperature of the battery must not exceed +60 °C (or the maximum temperature stated on the battery).
