INSTALLING BATTERY PACK

Your model includes a 7.2-volt battery pack. To properly balance 
the model, it should be installed in the battery compartment on the 
left side of the model. 
Follow these steps to 
install the battery:

Battery Installation

1. Open the battery 

compartment door 
by pressing on the 
release tabs.

2. Install the battery 

pack with the battery 
wires facing the rear 
of the model.

3. Route the battery 

wire through the slot 
near the vent.

4. Close the battery door, making sure not to pinch the battery 

wires. Be sure both release tabs are fully engaged with the door. 
Do not connect the battery pack to the ESC at this time. Note: 
always unplug the battery and remove from the model after use.

Using an Additional Battery Pack for Increased Run Time

Traxxas 1/16 models only require one battery pack, but the chassis can 
accept two batteries. The model can be run with two battery packs to 
extend run time. 

The batteries must be connected in parallel

, which 

will combine the capacity of the two batteries (for example, two 7.2-volt 
1000mAh packs connected in parallel will deliver a total capacity of 
2000mAh, but total voltage will remain 7.2 volts). This is easily done 
with a parallel Y-harness (part #3064, sold separately). Be sure to only 
use the Y-harness with identical battery packs; do not mix batteries of 
different chemistries or capacities.

 

Never connect the two batteries in 

series — this will fail the ESC!

Using LiPo Battery Packs in your model.

WARNING: 

The XL-2.5 is not directly compatible with LiPo 

batteries. The XL-2.5 is not equipped with low-voltage 

detection. 

For LiPo use, the XL-2.5 requires an external low-voltage 

detector (sold separately, consult your hobby dealer). 

THE TRAXXAS HIGH CURRENT CONNECTOR

Your model is equipped with the Traxxas 

High-Current Connector. Standard connectors 
restrict current flow and are not capable of 
delivering the power needed to maximize 
the output of your model. The Traxxas 
connector’s gold-plated terminals with a large contact surfaces 
ensure positive current flow with the least amount of resistance. 
Secure, long-lasting, and easy to grip, the Traxxas connector is 
engineered to extract all the power your battery has to give.

To run this model, your batteries must be equipped with Traxxas 

High-Current Connectors. Batteries can either be purchased new 
with Traxxas connectors installed or Traxxas connectors can be 
purchased to install on battery packs you already own. See sidebar 
for packages available from your hobby dealer.

For best performance, it is strongly recommended 
that you use only battery packs equipped with the 
Traxxas High-Current Connector. However, batteries 
with a Molex

®

 connector may be used in the model 

in conjunction with #3062 adapter.

When operating your model with two batteries for maximum 
run time, be careful to monitor the temperature of the 
speed control and motor to prevent overheating. If either 
component feels excessively hot, or the speed control’s 
thermal overload protection activates, 

stop running the 

model immediately and allow the components to cool.

Use the Right Batteries

Your transmitter uses AA batteries. 
Use new alkaline batteries, or 
rechargeable batteries such as 
NiMH (Nickel Metal Hydride) 
batteries in your transmitter. Make 
sure rechargeable batteries are 
fully charged according to the 
manufacturer’s instructions.
If you use rechargeable batteries 
in your transmitter, be aware that 
when they begin to lose their 
charge, they lose power more 
quickly than regular alkaline 
batteries. 
Caution: Discontinue running your 
model at the first sign of weak 
batteries (flashing red light) to 
avoid losing control.
