Additional Information About Lithium Rechargeable Batteries - Reely Rat Max Bedienungsanleitung

• Disconnect the battery from the model before connecting it to the charger. Never leave the battery con-
nected 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). Main-
tain enough distance to 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 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. This indicates an imminent risk of a fire or explo-
sion. 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 battery from the charger when it is fully charged.
• Never damage the casing of a rechargeable battery.
• Never charge damaged, leaking or deformed batteries. 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 rechargeable 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 bat-
teries and are more lightweight. This makes lithium batteries (especially lithium polymer batteries)
particularly suitable for use in model making.
However, lithium 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 batter-
ies and explains how these hazards can be avoided to ensure a long lifespan.
• The casing of many lithium batteries is made of a 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!
Pay attention to this when the rechargeable battery is attached to the model or removed from the model.
• Ensure that the rechargeable battery does not overheat during usage, recharging, discharging, transport
or storage. Do not place the rechargeable battery adjacent to sources of heat (e.g. cruise control, en-
gine), keep the rechargeable battery away from 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. (If neces-
sary follow additional manufacturer specifications for the battery!).
