B) Flight Battery - Reely X-140 RTF Operating Instructions Manual

b) Flight Battery

Attention!
Never leave the flight battery connected to the quadrocopter when you are not using it (e.g. during transport
or storage). Otherwise, the LiPo flight battery may be deep-discharged and is thus destroyed and rendered
useless! There is also a danger of malfunction due to interferences. The rotors could start up inadvertently
and cause damage or injury.
• Never damage the rechargeable battery. Damaging the casing of the rechargeable battery might cause
an explosion or a fire! Unlike conventional batteries/rechargeable batteries (e.g. AA or AAA type), the
casing of the LiPo rechargeable battery does not consist of a thin sheet but rather a sensitive plastic
film only.
• Never short-circuit the contacts of the rechargeable battery. Do not throw the battery or the product into
fire. There is a danger of fire and explosion!
• Charge the rechargeable battery regularly, even if you are not using the product. Due to the rechargeable
battery technology being used, you do not need to discharge the rechargeable battery first.
• Never charge the rechargeable battery of the product unattended.
• Never charge the LiPo flight battery immediately after use. Always leave the LiPo flight battery to cool
off first (at least 5 - 10 minutes).
• Charge the LiPo flight battery after removing it from the quadrocopter and only use the supplied USB-
LiPo-charger.
• Only charge intact and undamaged batteries. If the outer isolation of the rechargeable battery is
damaged or the battery is deformed or bloated, it must not be charged. In this case, there is immediate
danger of fire and explosion!
• Place the flight battery on a fire-resistant surface for charging (e.g. a plate). Keep a distance to flammable
objects (use USB extension cable if required).
• As the charger and the rechargeable LiPo flight battery both heat up during the charging procedure, it is
necessary to ensure sufficient ventilation. Never cover the charger or the flight battery!
• Never leave LiPo batteries unattended while charging them.
• Remove the flight battery from the charger when it is fully charged.
• The charger is intended for dry indoor use only. The charger and the flight battery must not become
damp or wet.
• There is the risk of fire or explosion by the rechargeable battery in case of error. LiPo batteries specifically
react very strongly at moisture and oxygen due to the chemicals contained in them! Do not expose the
charger, flight battery or quadrocopter to high/low temperatures or to direct solar radiation.
