• To charge the battery, place the charger and quadcopter on a non-ammable, heat-resistant surface
(e.g. stone tiles). Keep the charger and quadcopter away from ammable objects. Ensure that there is a
sufcient distance between the charger and the quadcopter.
• Do not charge batteries when they are still hot (e.g. due to a high discharge current in the model). Allow
the quadcopter battery to cool down to room temperature before charging it.
• Ensure that there is sufcient ventilation, as the quadcopter battery and charger may heat up during the
charging process. Never cover the charger or the quadcopter!
• 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 re or
explosion. If the quadcopter battery overheats or starts to expand, disconnect the quadcopter from the
charger immediately and take it to a location where it will not cause any additional damage if it explodes
or catches re (e.g. outdoors).
• Disconnect the quadcopter from the charger when the quadcopter battery is fully charged.
• Never damage the casing of a rechargeable battery. Never charge damaged, leaking or deformed bat-
teries. This may cause a re 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/Li-ion 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 signicantly higher capacity than NiMH and NiCd bat-
teries and are more lightweight. This makes LiPo (lithium polymer) or Li-ion 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 lm, 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 re or explosion!
The quadcopter battery is built into the quadcopter and cannot be replaced.
• Ensure that the lithium battery does not overheat during use, recharging, discharging, transport or stor-
age. Do not place the quadcopter (with the built-in battery) next to sources of heat or in direct sunlight.
This may cause the battery to overheat and trigger a re or explosion! The temperature of the battery
must not exceed +60 °C.
• Do not charge the battery if it is damaged or if the outer casing starts to swell/expand (e.g. after a crash).
This may cause a re or explosion!
If the battery is damaged, do not store the quadcopter in an apartment or in a house/garage. Damaged
or swollen lithium batteries may catch re.
