For Expert Drivers

• If a battery gets hot to the touch during the charging process 

(temperature greater than 140°F / 60°C), disconnect the battery fromthe 
charger and discontinue charging immediately.

• Always store battery packs safely out of the reach of children and pets.
• Do not short-circuit the battery pack. This may cause burns and severe 

damage to the battery pack and create the risk of fire.

• Do not expose the charger to water or moisture.
• Do not disassemble the charger.
• Use the supplied charger to charge the included battery. See “Charging the 

Battery Pack” on page 11. 

• Never leave batteries to charge unattended.
• Remove the battery from the model while charging.
• Always unplug the battery from the electronic speed control when the 

model is not in use and when it is being stored or transported.

• Allow the battery pack to cool off between runs (before charging).
• Children should have responsible adult supervision when charging and 

handling batteries.

• Do not use battery packs that have been damaged in any way.
• Do not use battery packs that have damaged wiring, exposed wiring, or a 

damaged connector. 

• 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.

• Nickel Metal Hydride batteries must be recycled or disposed of properly.  

Recycling Your Traxxas Power Cell NiMH Battery

Traxxas strongly encourages you to recycle your Power Cell NiMH 
battery when it has reached the end of its useful life. 

Do not throw your 

battery in the trash.

 All Power Cell NiMH battery packs display the RBRC 

(Rechargeable Battery Recycling Corporation) icon, indicating they are 
recyclable. To find a recycling center near you, ask your local hobby dealer 
or visit www.call2recycle.org.

LiPo Batteries

Lithium Polymer (LiPo) batteries are becoming 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 
procedures for long life and safe operation. 

WARNING: LiPo batteries 

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 
11.1 volts (3S packs). LiPo batteries have a minimum safe discharge voltage 
threshold that should not be exceeded. The Velineon VXL-3s 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.

 

It is the driver’s responsibility to stop immediately 

to prevent the battery pack from 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.

 

It is critical for you, the user, 

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. 

DO NOT ATTEMPT TO CHARGE LIPO BATTERIES OR ANY OTHER TYPE OF 
BATTERY WITH THE INCLUDED TRAXXAS CHARGER.

Speed Control

• Disconnect the Batteries

: Always disconnect the battery pack 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.

• Don’t Get Burned

: The heat sink can get extremely hot, so be careful not 

to touch it until it is cool. Supply adequate airflow for cooling.

• Use Stock Connectors

: If you decide to change the battery or motor 

connectors, only change one battery or motor connector at a time. This 
will prevent damage from accidentally mis-wiring the speed control. 
Please note that modified speed controls can be subject to a rewiring fee 
when returned for service. Removing the battery connector on the speed 
control or using the same-gender connectors on the speed control will 
void the product’s warranty.

• Insulate the Wires

: Always insulate exposed or damaged wiring with heat 

shrink tubing to prevent short circuits
