7. Notes on Batteries and Rechargeable Batteries
Although use of batteries and rechargeable batteries in everyday life is a matter of course today, there are
manydangersandproblems.InparticularwithLiPobatterieswiththeirhighenergycontent(ascomparedto
conventional NiCd or NiMH batteries), various provisions must be complied with to avoid danger of explosi-
onandre.
Therefore, always observe the following information and safety notes in handling of batteries and recharge-
able batteries.
• Keepbatteries/rechargeablebatteriesoutofthereachofchildren.
• Donotleaveanybatteries/rechargeablebatterieslyingaroundopenly.Thereisariskofbatteriesbeingswallowed
by children or pets. In this case, see a doctor immediately!
• Batteries/rechargeablebatteriesmustneverbeshort-circuited,disassembledorthrownintore.Thereisadanger
of explosion!
• Ifyoudonotuseitforanyextendedperiodoftime(e.g.duringstorage),removethebatteries/rechargeablebatteries
inserted in the transmitter to prevent damage from leaking batteries/rechargeable batteries. Disconnect the driving
battery from the speed controller completely and take it out of the vehicle.
• Leakingordamagedbatteries/rechargeablebatteriescancausechemicalburnstoskin.Wearsuitableprotective
gloves when handling them.
 Liquidsleakingfrombatteries/rechargeablebatteriesarechemicallyhighlyaggressive.Objectsorsurfacesthat
come into contact with them may take severe damage. Therefore, keep batteries/rechargeable batteries in a suita-
ble location.
• Neverrechargenormal(non-rechargeable)batteries.Thereisariskofreandexplosion!Onlychargerechargeable
batteries intended for this purpose. Use suitable battery chargers.
• Observecorrectpolaritywheninsertingbatteries/rechargeablebatteriesorconnectingthedrivebatteries(observe
plus/+ and minus/-).
• Nevermixbatteriesandrechargeablebatteries!Usebatteriesorrechargeablebatteries,e.g.forthetransmitter.
• Alwaysreplacetheentiresetofbatteriesorrechargeablebatteriesinthetransmitter.Nevermixfullychargedbat-
teries/rechargeable batteries with partially discharged ones. Always use batteries or rechargeable batteries of the
same type and manufacturer.
• Abatterychargercorrespondingtothebatterytechnology(NiCd,NiMH,LiPo....)isrequired.Neverleave,e.g.,LiPo
batteriesunattendedinanNiMHcharger!Thereisariskofreandexplosion!
• Asuitablebalancerisrequiredforchargingmulti-cellLiPobatteries(frequentlyalsocalledan„Equalizer“).Good
LiPochargersusuallyhavethisinstalledalready;otherwise,anexternalbalancerisrequired.Thebalancerprevents
overchargingoftheLiPocellsbyinspectionandadjustmentoftheindividualcellvoltages.
 WhenoverchargingaLiPocell(max.cellvoltage4.24V),theLiPobatterymaybloatorevencatchreorexplode!
• Onlychargeintactandundamagedbatteries.Iftheouterisolationoftherechargeablebatteryorbatteryhousingis
damaged or the battery is deformed or bloated, it must not be charged. In this case, there is immediate danger of
reandexplosion!
• Neverchargethebatteryrightafteruse.Alwaysleavetherechargeablebatteriestocooloffrst(atleast5-10
minutes).
• Removethedrivebatteriesfromthemodelforrecharging.
