8. Battery charging
a) Charging the vehicle‘s drive battery
• Drivebatteriesarenotincludedwiththethevehicle;thesemustbepurchasedseparately.Thus,itisyourchoice
whether using a low-cost entry-level battery for the vehicle or a high-quality, professional, large capacity battery.
• Usually,thedrivebatteryissuppliedemptyandneedstobecharged.Beforeadrivebatterycandeliveritsmaxi-
mum power, several complete discharge and charge cycles are required.
• If you still use the „old“ NiCd drive batteries, they should always be completely „empty“, if possible, as the multiple
charging of a „half-full“ NiCd battery may result into the so-called „Memory Effect“. This means that the drive battery
loses its capacity, it does not provide any more the entire energy stored, the driving time deceases.
Recharging partially discharged batteries with NiMH or LiPo technology is no problem. A previous discharging is
usually not required.
• Higher quality drive batteries have not only a higher capacity, so that you can drive the model vehicle longer, but
also a higher output voltage under load. Therefore, more power for the motor is available which is demonstrated by
better acceleration and a higher speed.
• We encourage you purchasing a high-quality charger. Usually, this offers fast charging of the battery as well. If you
want to use a LiPo drive battery for the vehicle, then the charger must have a balancer.
• The batteries heat up during charging or discharging (while driving the vehicle). Charge the batteries only when they
havecooleddowntoroomtemperature.Thesameappliestothechargingprocess;usethebatteryinthevehicle
onlywhenthebatteryhascooleddownsufcientlyaftercharging.
• Only use a charger that is suitable for the battery type you are using (e.g. LiPo).
• For the charging process, remove the drive battery from the vehicle and disconnect it from the speed controller.
b) Charging the transmitter batteries
• Perhapsthebuilt-intransmitterdoesnothaveachargingsocket;observetheoperatinginstructionssuppliedforthe
transmitter.Inthiscase,removetheinsertedbatteriesandrechargethemexternally.
If the transmitter has a charging socket, then check whether the batteries are actually inserted before con-
necting a charger to the transmitter‘s charging socket. When charging non-rechargeable batteries there is
ariskofreandexplosion!
• Thebatteriesinthetransmittermustnotbechargedusingquickcharging,asthiswilldamagethetransmitter;the
cellsinthetransmittercanalsoheatuptoomuch.Forthemaximumpermissiblechargecurrent,payattentionto
the information on the sender or in the operating instructions of the remote control system.
• We recommend that you do not to charge the batteries directly in the transmitter, but outside of the transmitter (with
a high-quality charger for individual cells). Depending on the batteries, higher charging currents may be used here.
• Onlyuseachargerthatisdesignedforthespecicnumberofcellsinsidethetransmitterandthecorresponding
battery type.
