8. Charging Rechargeable Batteries
a) Charging the Drive Battery for the Vehicle
• Arechargeabledrivebatteryisnotincludedinthedeliveryandmustbeorderedseparately.Thisenablesyouto
choose whether you want to use a low-cost beginner's rechargeable battery pack or a high-quality professional bat-
tery pack which has a higher capacity.
• Therechargeabledrive batteryisdelivered unchargedandmust becharged.Several complete dischargeand
charge cycles are necessary before the drive battery delivers its maximum power.
• Ifyouarestillusing"old"NiCddrivebatteries,theyshouldberun"empty"atalltimes,becauserepeatedcharging
of a "half-full" NiCd drive battery can cause a memory effect. That means that the drive battery loses its capacity; it
no longer releases all of its stored energy and the driving time is decreased.
 ForrechargeablebatterieswithNiMHorLiPotechnology,rechargingpartiallydischargedrechargeablebatteries
does not cause any problems. Previous discharge is usually not required.
• High-qualityrechargeabledrivebatteriesnotonlyhaveahighercapacity,whichallowsyoutodriveyourmodelcar
much longer, but also deliver a higher output voltage for extreme situations. This gives the motor more power and
results in better acceleration and higher speed.
• Werecommendpurchasingahigh-qualitycharger.Suchachargerusuallyhasaquick-chargingfeature.Ifyouwant
touseaLiPodrivebatteryforyourvehicle,thechargermusthaveabalancer.
• Rechargeablebatteriesheatupduringcharging/discharging(drivingthevehicle).Waituntiltherechargeablebatter-
ies have reached room temperature before charging them. The same applies after the charging procedure. Do not
usetherechargeablebatteryinthevehicleuntilithascooleddownsufcientlyafterthechargingprocess.
• Onlyuseachargersuitableforthebatterytypeused(e.g.LiPo).
• Removethedrivebatteryfromthevehicleforcharginganddisconnectitfromthespeedcontroller.
b) Charging Rechargeable Batteries in the Transmitter
• Theincludedtransmittermaynothaveachargingsocket;observetheincludedoperatinginstructionsforthetrans-
mitter. In this case, remove the inserted batteries and charge them externally.
If your transmitter has a charging socket, check whether there are actually rechargeable batteries inserted
in the transmitter before connecting the charger. When charging normal (non-rechargeable) batteries, there
isariskofreandexplosion!
• Rechargeablebatteriesinthetransmittermustnotbequick-charged,asthisdamagesthetransmitterandexces-
sively heats the cells inside the transmitter. Observe the maximum permissible charging current as indicated on the
transmitter or in the operating instructions of the remote control system.
• Wedonotrecommendtochargebatteriesdirectlyinthetransmitter,itisbettertochargethemoutsidethetransmit-
ter(usingahigh-qualitychargerforindividualcells).Here,higherchargecurrentscanbeuseddependingonthe
rechargeable batteries.
• Onlyuseachargerdesignedfortherespectivenumberofcellsinthetransmitterandthecorrespondingrecharge-
able battery type.
