• Use the Factory-Installed Stock Connectors: Do not change the battery and 

motor connectors. Improper wiring can cause fire or damage to the ESC. 
Please note that modified speed controls can be subject to a rewiring fee 
when returned for service.

• No Reverse Voltage: The ESC is not protected against reverse polarity 

voltage. 

• Always adhere to the minimum and maximum limitations of the speed 

control as stated in the specifications table in the Owner’s Manual. If your 
ESC operates on two batteries, do not mix battery types and capacities. Use 
the same voltage and capacity for both batteries. Using mismatched battery 
packs could damage the batteries and electronic speed control.

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. 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, which 
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. 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.

Important Warnings for users of Lithium Polymer (LiPo) batteries:

Lithium Polymer (LiPo) batteries are significantly more volatile than 
other rechargeable batteries. 

ONLY use a Lithium Polymer (LiPo) balance charger with a balance 
adapter to charge LiPo batteries, such as the Traxxas EZ-Peak Plus 
Charger, part #2933, or the 2-Cell /3-Cell LiPo Balance Charger, part #2935. 
The use of a NiMH or NiCad charger or charge mode will damage the 
batteries and may cause fire and personal injury.

WARNING!   CAUTION!   DANGER! 

FIRE HAZARD!

 

Charging and discharging batteries has the potential for 

fire, explosion, serious injury, and property damage if not performed per the 
instructions. In addition, Lithium Polymer (LiPo) batteries pose a SEVERE risk of 
fire if not properly handled per the instructions. Before use, read and follow all 

manufacturer’s instructions, warnings, and precautions. Never allow children under 14 years old 
to charge or use LiPo batteries without the supervision of a responsible, knowledgeable adult.

• While charging or discharging, ALWAYS place the battery (all types of batteries) in a fire 

retardant/fire proof container and on a non-flammable surface such as concrete.

• ALWAYS charge batteries in a well-ventilated area.

• REMOVE flammable items and combustible materials from the charging area.

• ONLY use a Lithium Polymer (LiPo) balance charger with a balance adapter to charge LiPo 

batteries.

• If any battery or cell is damaged in any way, DO NOT charge, discharge, or use the battery.

• BEFORE you charge, ALWAYS confirm that the charger settings exactly match the battery 

type (chemistry), specification, and configuration to be charged.

• DO NOT exceed the maximum manufacturer recommended charge rate.

• DO NOT disassemble, crush, short circuit, or expose the batteries to flame or other source  

of ignition.

• NEVER leave batteries unattended while charging.

This model is not intended 
for use by children under 
14 years of age without the 
supervision of a responsible 
and knowledgeable adult.
