8. Charging Rechargeable Batteries
a) Charging the Drive Battery for the Vehicle
• Norechargeabledrivebatteryisincludedinthedelivery.It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 battery pack
which has a higher capacity.
• The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drivebatteriesnotonlyhaveahighercapacity,whichallowsyoutodriveyourmodelvehiclemuch
longer, but also deliver a higher output voltage under load. 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whenchargedordischarged(drivingthevehicle).Waituntiltherechargeablebat-
teries 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heats
up the cells in the transmitter excessively. Observe the maximum permissible charging current as indicated on the
transmitter or in the operating instructions of the remote control system.
• Werecommendnotchargingrechargeablebatteriesdirectlyinthetransmitterbutwithahigh-qualitychargerfor
individualcellsinstead.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.
