• Disconnect the battery from the model before connecting it to the charger. Never leave the battery con-
nectedtoaspeedcontrollerwhenitischarging.Thismaydamagethecharger,speedcontrollerorthe
battery! Always remove the drive battery from the model before charging it.
• Placethechargeranddrivebatteryonanon-ammable,heat-resistantsurface(e.g.stonetiles).Main-
tainenoughdistancetoammableobjects.Maintainasufcientdistancebetweenthechargerandthe
drive battery. Never place the drive battery on top of the charger.
• Do not charge batteries when they are still hot (e.g. due to a high discharge current in the model). Allow
the battery to cool down to room temperature before charging it.
• Ensurethatthereissufcientventilation,asthebatteryandchargermayheatupduringthecharging
process. Never cover the charger or the rechargeable battery!
• 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explo-
sion. If the battery overheats or starts to expand, disconnect it 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 battery from the charger when it is fully charged.
• Never damage the casing of a rechargeable battery.
• Neverchargedamaged,leakingordeformedbatteries.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 rechargeable 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signicantlyhighercapacitythanNiMHandNiCdbat-
teries and are more lightweight. This makes lithium batteries (especially lithium polymer 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!
Pay attention to this when the rechargeable battery is attached to the model or removed from the model.
• Ensure that the rechargeable battery does not overheat during usage, recharging, discharging, transport
or storage. Do not place the rechargeable battery adjacent to sources of heat (e.g. cruise control, en-
gine),keeptherechargeablebatteryawayfromdirectsunlight.Thismaycausethebatterytooverheat,
whichcancauseareorexplosion!Thetemperatureofthebatterymustnotexceed+60°C.(Ifneces-
saryfollowadditionalmanufacturerspecicationsforthebattery!).
