Handling The Lipo-Battery Pack - Carson CESSNA 182 Manual De Instrucciones

HANDLING THE LiPo BATTERY PACK
LiPo batteries (Lithium-Polymer) are state of the art
electric power sources with high capacity in
relation to their weight. Handling such batteries
requires special care to avoid possible hazards
and premature loss of power with regards to
charging and discharging as well as storing and
any other kinds of handling. Non-observance of
instructions and warnings can rapidly affect loss of
power, shortening of service life or defects even
under certain circumstances cause the battery to
ignite. After the flight and at the end of charging,
the battery may become hot. Within certain limits
this is a normal process.
The 100/240V charger included in the aeroplane
kit consists of a power adapter, which should be
connected to a standard socket, and a LiPo
balancing charger. It delivers a current up to 1.25A
at 12.8V voltage, giving a charging time for the
LiPo battery of approximately 1 hour. The charger
/ balancing unit can also be set to a lower voltage
for slower and more gentle charging which results
in better battery life.
1. Connect the power adapter to the LiPo
balancing charger. 2. Plug the power adapter
into a socket.
3. Push the white (balancer) plug of the LiPo
battery into the charger socket. 4. To avoid a
short circuit check that the plug connectors are
firmly connected.
5. Towards the end of the charging time check for
excessive heating of the battery. The
temperature must not exceed 50°C. If it reaches
this temperature, disconnect the battery.
5. Charging is complete when the green LED is
illuminated, and the charger should be
disconnected from the power supply as soon as
possible.
Disposal of worn out or damaged batteries
Dispose of battery properly. The durability of NiMH
battery packs depends on the kind of use and
current consumption. If a steady high current is
consumed e.g. during fast flying with high rpm,
about 250 charge / discharge cycles are possible.
A reduction in capacity will also be noticed sooner.
A worn out (only very low capacity) or damaged
battery pack (wrapper damaged, worn cable) has

LiPo batteries are very sensitiv to deep discharge
where the voltage drops to les than 3V per cell;
they can be permanently damage by this process.
The electronic speed controller (ESC) is equipped
with a safety switch that prote ts against under
voltage by shutting down the mot r; the remaining
voltage is sufficient to maintai control in a power-
off glide.
Depending on the way you fly, the voltage of your
LiPo battery pack will drop at some stage resulting
in a lower rpm of the motor combined with reduced
climbing ability of your model.
As soon as you realise this fact you should start to
land. Landing with not enough or no power is
always difficult and you may not have sufficient
power to reach your intended landing point.
Short circuits must be absolutely avoided; they can
cause great heat and melt the wire insulation and
can ignite surrounding combustible material.
The battery pack may be rather hot after a flight.
It is prohibited to charge the battery pack inside the
model and we recommend removal of the battery
after each flight and storage in a safe place.
