Manual
20. Safety Notes
Damage to the aluminum laminate sheathing: LLithium polymer cells must never be opened, separated, deformed, bent
or brought into contact with other packs or soldered. Soldering tags must not be bent, torn or thrown to the ground. This
can cause an internal short circuit and an explosion with flame formation. Also, be aware that the electrolyte fluid contained
in an LiPo battery is harmful to health.
Usage:
Never use a LiPo battery with other batteries. An unwanted discharge can destroy the LiPo cells or the battery used.
!WARNING!
Due to the enormous energy density, lithium-polymer cells can ignite or even explode when damaged.
This can be caused by extreme overcharging, accident or mechanical damage, etc.
It is therefore extremely important to monitor the charging process. After an accident, the pack should be checked at the
very least. For example, the pack may have been damaged by an accident but will only heat up after half an hour. In case of
damage, keep the pack under the most careful observation. The use of a defective battery in an electronic device can cause
damage to it.
Case of Fire:
If lithium polymer cells catch fire, do not use water as a extinguisher, as this will only foster and aggravate the
fire! Please ask your local fire brigade for suitable extinguishing material which should always be within reach (eg dry sand).
Also avoid inhalation of the lithium gases, as this can lead to irritation of the mucous membranes, cough, breathing prob-
lems and laryngeal inflammation. These complaints can also occur with a time lag.
Disposal:
Batteries contain toxic substances. Therefore, do not throw used lithium polymer cells into the household waste,
but dispose of them accor-ding to the relevant laws. To avoid accidental short-circuiting, always tape the battery pack with
an insulating tape.
Lithium cells may only be discharged into the battery collecting receptacles when they are unloaded in the case of trade
and public waste disposal vehicles. If the cells are not fully discharged, these must be protected against short circuits as a
precaution on the poles with adhesive tape.
Safety when handling lithium-polymer batteries is only guaranteed if the safety instructions described above are follo-wed
and the LiPo's are not subjected to any extraordinary stress.
Improper use can destroy the cells or result in personal injury.
We can not be held responsible for any damage to persons, models or cells.
About the technology
: Lithium-ion polymer batteries (in short: LiPo) are completely based on Li-Ion technology.
The difference to the Li-Ion battery is in the electrolyte.
It was thickened and combined with a polymer film. Thus, it is no longer liquid or semi-liquid. These characteristics result in
an extremely flat battery with a very high energy density with 3.7 V instead of 3.6 V with Li-Ion.
Current rating:
This varies depending on the manufacturer between 2C and 90C. Please pay attention to the manufactu-
rer's instructions. Please be sure to comply with the legal requirements for operating drones in your country and make sure
that you do not violate any of these requirements.
Charging:
The rechargeable battery can be recharged at any time, it does not have a „lazy effect" and must never be unloa-
ded manually. If the battery is discharged below 3V, it must be charged with 0.1C up to approx. 3 - 3.6V. This ensures a gentle
summons. The battery is then charged up to the charging voltage of 4.2 V (exactly: 4.235 V) with 0.5 - 1 C. A charging current
of 2C is also possible, but can shorten the life of a battery (please note the manufacturer's instructions).
A must for the battery care are LIPOBALANCER. The use of such a device leads to a significantly longer running time of the
LiPo batteries. A balancer ensures that no overcharging takes place. For a transfer it may, inter alia, also come when the cells
of a pack drift over time, there are various causes for this. Deviations occur, for examp-le, after prolonged storage due to
different self-discharges or different charging effects after several charging cycles.
