SAFETY PRECAUTIONS
Your model is able to use LiPo  
                         batteries. Charging and discharging batteries has the 
potential for fire, explosion, serious injury, and property damage 
if not performed per the instructions. Before use, read and follow 
all manufacturer’s instructions, warnings, and precautions. In 
addition, Lithium Polymer (LiPo) batteries pose a SEVERE risk of 
fire if not properly handled per the instructions and require special 
care and handling procedures for long life and safe operation. 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. Dispose of used batteries according to the 
instructions.
Important Warnings for users of Lithium Polymer (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 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 is just one part of a comprehensive plan 
for safe LiPo battery use. It is critical to follow all instructions for 
safe and proper charging, use, and storage of LiPo batteries. Make 
sure you understand how to use your LiPo batteries. 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.
• ONLY use a Lithium Polymer (LiPo) balance charger with a balance 
adapter port to charge LiPo batteries. Never use NiMH or NiCad-
type chargers or charge modes to charge LiPo batteries. DO NOT 
charge with a NiMH-only charger. The use of a NiMH or NiCad 
charger or charge mode will damage the batteries and may cause 
fire and personal injury.
• NEVER charge LiPo battery packs in series or parallel. Charging 
packs in series or parallel may result in improper charger cell 
recognition and an improper charging rate that may lead to 
overcharging, cell imbalance, cell damage, and fire. 
FIRE HAZARD!
WARNING! CAUTION! DANGER!
• ALWAYS inspect your LiPo batteries carefully before 
charging. Look for any loose leads or connectors, 
damaged wire insulation, damaged cell packaging, impact 
damage, fluid leaks, swelling (a sign of internal damage), cell 
deformity, missing labels, or any other damage or irregularity. 
If any of these conditions are observed, do not charge or use 
the battery pack. Follow the disposal instructions included with 
your battery to properly and safely dispose of the battery. 
• DO NOT store or charge LiPo batteries with or around other 
batteries or battery packs of any type, including other LiPos.
• Store and transport your battery pack(s) in a cool dry place. 
DO NOT store in direct sunlight. DO NOT allow the storage 
temperature to exceed 140°F or 60°C, such as in the trunk of a 
car, or the cells may be damaged and create a fire risk. 
• DO NOT disassemble LiPo batteries or cells.
• DO NOT attempt to build your own LiPo battery pack from 
loose cells.
Charging and handling precautions for all battery types:
• BEFORE you charge, ALWAYS confirm that the charger 
settings exactly match the type (chemistry), specification, and 
configuration of the battery to be charged. 
• DO NOT attempt to charge non-rechargeable batteries (explosion 
hazard), batteries that have an internal charge circuit or a 
protection circuit, batteries that have been altered from original 
manufacturer configuration, or batteries that have missing or 
unreadable labels, preventing you from properly identifying the 
battery type and specifications.
• DO NOT exceed the maximum manufacturer recommended charge 
rate.
• DO NOT let any exposed battery contacts or wires touch each other. 
This will cause the battery to short circuit and create the risk of fire.
• 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.
• DO NOT charge batteries inside of an automobile. DO NOT charge 
batteries while driving in an automobile. 
• NEVER charge batteries on wood, cloth, carpet, or on any other 
flammable material.
