Battery (LiPo) – General information
ARF-MikroKopters use Lithium-Polymer-Batteries, called LiPo. The ARF-MikroKopter is designed for the use with 4S
(14,8V) LiPos. The right LiPos can be purchased through us.
The ARF-MikroKopter monitors the battery during the flight. If the voltage gets low, a warning tone will sound from the
buzzer on the Kopter.
This alarm is also signaled by an existing telemetry transmission on the transmitter (with the HoTT system) or PC (when
viewing in the MKTool OSD).
Once this alarm sounds, land i mmediately and load or change the LiPo..
Continuing the flight with a warning signal can permanently damage the LiPo and the Kopter could crash.
After landing the Copter and turning off the motors the connection between LiPo and copter should be seperated. Keep
the battery pack out of the ARF-MikroKopter if that one is not used (e.g. storage or transport). That avoids a fully
discharge of the battery.
Do not charge the LiPo directly after landing. Let the LiPo always cool down. Improper handling of LiPos causes burns /
explosion hazard! Do not use damaged or defective LiPos!
Before using the LiPo the first time it must be fully charged!
The first charge of LiPos, depending on the charge level of the individual cells and operation / performance
of the charger been used, will take up to several hours.
The proper charging and discharging of the cells / LiPos can not be monitored by us. Any warranty is
excluded for incorrect charging or discharging.
Safety rules for LiPos
Lithium-Polymer-batteries (LiPo) require particulary careful treatment. This applies to charging, discharging, storage and
other handling. Incorrect usage / treatment of LiPos can cause performance problems, explosion, fire, smoke, poisoning
and other problems.
Do not cause short circuits as permanent short circuits lead to the destruction of the battery. High temperatures and
possibly spontaneous combustion can be the result !
Each charge / discharge and storage at too high / low temperatures reduces the capacity of the battery. The
recommended temperature range for charging and storing LiPo - batteries is 0-50° C.
A battery is a wearing part. Please be aware that batteries will wear out with use, and flight time will decrease.
For charging LiPo batteries the approved charger with the appropriate charging cable must be used. The max. loading
capacity must be limited to 1.05 times of the battery capacity.
(Example: 5000mAh Akku = 5250mAh max. loading capacity)
Use for charging and discharging of LiPo batteries only the especially designed charger / discharger.
The battery temperature should not rise above 70°C during the discharge.
Make sure that the number of cells and the charge voltage are set correctly. A voltage above 4,25V per cell must be
avoided otherwise the cell will be damaged permanently.
Further information about the settings get out of your instruction manual of your charger / discharger.
The battery which need to be charged must be while charging on a non-flammable, heat resistant and not conductive
surface ! Combustible or flammable materials need to be away from the charging spot. Charge batteries only under
supervision !
To store LiPos they should have a charge level of around 10-20%. During the storage the LiPos should be reviewed
regulary. This is easy with a LiPo-Tester. If the voltage of the cells go down to 3V they must be necessarely charged.
Deep-discharge and storage in discharged condition (cell voltage less than 3V) makes the battery useless..
The foil / outer shell of the LiPo can be easily damaged by sharp objects such as needles, knives, nails, etc. If the foil is
damaged it makes the battery useless..
Mechanical shocks e.g. throughout dropping, hitting, bending etc. can also make the LiPo unusuable.
Do not use damaged batteries under no circumstances ! Damaged or exhausted batteries are hazardous waste and
must be disposed accordingly.
If a LiPo is damaged, avoid any direct contact with the electrolyte. By contact with the skin, eyes or other body parts you
