7. Information 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 in LiPo batteries with high energy content (as compared to con-
ventionalNiMHbatteries),variousprovisionsmustbecompliedwithtoavoiddangerofexplosion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. If swallowed, consult a doctor immediately!
• Batteries/rechargeablebatteriesmustneverbeshort-circuited,disassembledorthrownintore.Thereisadanger
of explosion!
• Nevermixbatteriesandrechargeablebatteries!Usebatteriesorrechargeablebatteries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.
• Batteriesmustnotgetdamporwet.ThiscanresultinareorexplosionwithLiPobatteries!
• Alwaysobserveproperpolarity(observeplus/+andminus/-),e.g.wheninsertingbatteriesintothetransmitteror
connecting a rechargeable battery to a charger.
• 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 drive
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oncontact;therefore,use
suitable protective gloves.
• 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.
• Donotrechargeanynormal,non-rechargeablebatteries.Thereisariskofreandexplosion!Onlychargerechar-
geable batteries intended for this purpose. Use suitable battery chargers.
• Abatterychargercorrespondingtobatterytechnology(NiMH,LiPo....)isrequired.Neverleave,e.g.,LiPobatteries
unattendedinanNiMHcharger!Thereisariskofreandexplosion!
The enclosed plug-in charger is only suitable for charging a 6-cell NiMH rechargeable battery (e.g. the enclosed
NiMH drive battery).
• Asuitablebalancerisrequiredforchargingmulti-cellLiPobatteries(usuallyintegratedingoodLiPochargers).A
balancer (frequently also referred to as an equalizer) prevents overcharging of a single LiPo cell by inspection and
correction 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!
• Neverchargethebatteryrightafteruse.Alwaysleavetherechargeablebatteriestocooloffrst(atleast5-10
minutes).
