b) Additional Information about Lithium Batteries
Modernbatterieswithlithiumtechnologydonotonlyhaveaclearlyhighercapacity
thanNiMHorNiCdrechargeablebatterypacksbuttheyalsohaveaconsiderably
lowerweight.Thismakesthistypeofrechargeablebatteryveryinterestingforap-
plicationinmodelconstruction;so-calledLiPobatteries(lithium-polymer)areoften
usedhere.
Rechargeablelithiumbatteriesrequirespecialcarewhencharging/discharging,as
wellasduringoperationandhandling.
Forthisreason,wewouldliketoprovideyouwithsomeinformationinthesections
belowaboutthedangersandhowyoucanavoidthem,thushelpingsuchbatteries
tomaintaintheirperformanceforanextendedperiodoftimetocome.
• Theoutershellofmanyrechargeablelithiumbatteriesisonlymadeofathickfoil
andthereforeverysensitive.
Neverdestroyordamagethebattery,neverletthebatteryfallanddonotpierce
thebatterywithanyobjects!Avoidanymechanicalstrainonthebattery;neverpull
theconnectioncablesofthebattery!Thereisariskofreandexplosion!
Theseguidelines must alsobeobserved whenthebattery is insertedinto the
modelorwhenitisremovedfromthemodel.
• Ensurethatthebatterydoesnotoverheatduringusage,recharging,discharging,
transportorstorage.Donotplacethebatterynexttosourcesofheat(e.g.speed
controller,motor),keepthebatteryawayfromdirectsunlight.Thereisariskofre
andexplosionifthebatteryoverheats!
Thebatterymust never heatuptomore than +60°C(observeany additional
informationfromthemanufacturer!).
• Ifthebatteryisdamaged(e.g.afterthecrashofanaircraftorhelicoptermodel)or
theexteriorcoverissoaked/hasexpanded,donotusethebattery.Donotcharge
itanymore.Thereisariskofreandexplosion!
Handlethebatterywithcare,usesuitableprotectivegloves.Disposeoftherechar-
geablebatteryenvironmentallycompatibly.
Neverkeepsuchrechargeablebatteriesinanapartmentorahouse/garageany-
more.Damagedorbloatedlithiumrechargeablebatteriesmaycatchresuddenly.
• Onlyuseasuitablechargertochargelithiumbatteriesorusethecorrectcharging
procedure.Duetoariskofreandexplosion,conventionalchargersforNiCd,
NiMHandleadbatteriesmustnotbeused!
Alwayschoosetherightchargingproceduredependingonrechargeablebattery.
• Whenchargingalithiumbatterywithmorethanonecell,alwaysuseaso-called
balancer(oneisalreadyintegratedintothesuppliedcharger).
• ChargeLiPobatterieswithamax.chargingcurrentof1C(ifnotindicatedother-
wisebythebatterymanufacturer!).Thismeansthatthechargingcurrentmaynot
exceedthecapacityvalueimprintedonthebattery(e.g. batterycapacity1000
mAh,max.chargingcurrent1000mA=1A).
WithLiFe,LiIonandLiHVbatteries,youmustobservetheinstructionsofthebat-
terymanufacturer.
• Thedischargingcurrentmustnotexceedthevalueprintedonthebattery.
Forexample,ifavalueof“20C”isprintedonaLiPobattery,themax.discharging
currentis20timesthebattery’scapacity(e.g.batterycapacity1000mAh,max.
dischargingcurrent20C=20x1000mA=20A).
Otherwise,thebatterywilloverheat,causingdeformation/bloatingofthebattery
orexplosionandre!
Theprintedvalue(e.g“20C”)doesnotgenerallyrefertotheconstantcurrent,but
tothemaximumcurrentthatthebatteryiscapableofproducingintheshort-term.
Theconstantcurrentthereforeshouldnotbehigherthanonehalfofthegiven
value.
• Observethatthe individual cells ofalithiumrechargeablebatterymustnotbe
deep-discharged.Adeepdischargeofalithiumrechargeablebatterywillleadto
permanentdamage/destructionoftherechargeablebattery.
Ifthemodeldoesnotprovideprotectionagainsttotaldischargeorpossessavi-
sualdisplayindicatingalowbattery,remembertoswitchoffthemodelintime.
