7. Charging the batteries
a) Charging the Driving Batteries for the Vehicle
• The vehicle requires two driving batteries of the same build (see “Technical Data” at the end of these instructions).
• The model is delivered without any driving batteries. They must be purchased separately. You can chose whether
you want to use low-cost battery packs for beginners or high-quality professional battery packs with a high capacity.
• The driving batteries are delivered uncharged and must be charged.
• Before the rechargeable driving battery delivers its maximum power, several complete discharge and charge cycles
are necessary.
• Always use up NiCd driving batteries completely as recharging a “half-full” battery pack repeatedly can cause the so-
called memory effect. That means that the driving battery loses its capacity; it no longer releases all of its stored
energy and the driving time is decreased.
In case of rechargeable batteries with NiMH technology or LiPo batteries, recharging partially discharged recharge-
able batteries does not cause any problems.
• High-quality rechargeable driving 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 provides the motor with more
power and results in better acceleration and higher speed.
• If you are using several driving batteries or rechargeable batteries, purchasing a high-quality charger may be worth-
while. Such a charger usually has a quick-charging feature.
• 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 batteries in the vehicle until they have cooled down sufficiently after the charging process.
b) Charging Rechargeable Batteries in the Transmitter
It is possible that the provided transmitter does not have a charging socket. 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 fire and explosion!
• We recommend not charging rechargeable batteries directly in the transmitter but with a high-quality charger for
individual cells instead.
• Rechargeable batteries in the transmitter must not be quick-charged as this damages the transmitter and heats up
the cells in the transmitter excessively. Depending on the batteries used, we recommend a maximum charging
current of 200-300 mA. Please note the label on the charging socket or the type plate of the transmitter.
• Only use a charger designed for 8 AA batteries and the corresponding battery type (NiCd, NiMH).
