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
battery 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.
• Rechargeablebatteriesheatupduringcharging/discharging(drivingthevehicle).Waituntiltherechargeablebatte-
ries 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.
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excessi-
vely 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trans-
mitter (using a high-quality charger for individual cells). Here, higher charge currents can be used depending on the
rechargeable batteries.

able battery type.
