SAFETY PRECAUTIONS
• Only use approved chargers for NiMH battery packs (such as the
Traxxas EZ-Peak Plus Charger, part #2933). Do not exceed the
maximum charge rate of 4 amps.
• Do not short-circuit the battery pack. This may cause burns and severe
damage to the battery pack.
• Do not burn or puncture the batteries. Toxic materials could be
released. If eye or skin contact occurs, flush with water.
• Store the battery pack in a dry location, away from heat sources and
direct sunlight.

LiPo Batteries
Lithium Polymer (LiPo) batteries are popular for use in R/C models due
to their compact size, high energy density, and high-current output;
however, these types of batteries require special care and handling

are intended only for advanced users that are educated on the risks
associated with LiPo battery use.
Traxxas does not recommend that
anyone under the age of 14 use or handle LiPo battery packs without
the supervision of a knowledgeable and responsible adult.
Your model is able to use LiPo batteries with nominal voltage not to
exceed 7.4 volts (2S packs) for each battery (4S total). LiPo batteries
have a minimum safe discharge voltage threshold that should not
be exceeded. The electronic speed control is equipped with built-in
Low-Voltage Detection that alerts the driver when LiPo batteries have
reached their minimum voltage (discharge) threshold.

being discharged below its safe minimum threshold.
Low-Voltage Detection on the speed control is just one part of a
comprehensive plan for safe LiPo battery use.
to follow all other instructions supplied by the battery manufacturer
and the charger manufacturer for proper charging, use, and storage
of LiPo batteries. Do not attempt to charge LiPo batteries with the
Traxxas charger included in this package. Make sure you understand
how to use your LiPo batteries.
Be aware that Traxxas shall not be liable
for any special, indirect, incidental, or consequential damages arising out
of the installation and/or use of LiPo batteries in Traxxas models. If you
have questions about LiPo battery usage, please consult with your local
hobby dealer or contact the battery manufacturer. As a reminder, all
batteries should be recycled at the end of their useful life.

SPEED CONTROL

Your model's electronic speed control (ESC) is an extremely powerful
electronic device capable of delivering high current. Please closely
follow these precautions to prevent damage to the speed control or
other components.
• Disconnect the Batteries: Always disconnect the batteries from the
speed control when not in use.
• Transmitter on First: Switch on your transmitter first before switching
on the speed control to prevent runaways and erratic performance.
Do not throw your
