The Traxxas High-Current Connector
Your model is equipped with the patented
Traxxas High-Current Connector. Standard
connectors restrict current flow and are not
capable of delivering the power needed to maximize the output of
the Velineon Brushless Power system.
The Traxxas connector’s gold-plated terminals with 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.
Using LiPo Packs in Your Model
The VXL-3m is compatible with 2S and 3S LiPo packs, and is
equipped with Low-Voltage Detection circuitry to prevent over-
discharging. Make certain LiPo mode is selected (see page 17 for
details) when using LiPo packs in your model.
Using an Additional Battery for Increased Run Time
Your model only requires one battery pack, but the chassis can
accept two batteries. Your 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.
Using an Additional Battery For Increased Speed
An additional battery may also be used to increase the top speed of
your model to 40+mph by connecting the batteries in series using
a Traxxas series connector (Part #3063, sold separately).
40+mph Battery Installation Instructions
1. Install the supplied battery as described on page 11.
2. Install an identical Power Cell Series 1 battery (#2925, sold
separately) in the opposite battery compartment.
3. Plug both batteries into the Y-harness (sold separately). The
harness connects the two packs in series. The two 7.2-volt 6-cell
battery packs will operate as one 14.4-volt 12-cell battery pack.
4. Plug the Y-harness into the speed control.
RADIO SYSTEM RULES
• Always turn your transmitter on first and off last. This procedure
will help to prevent your model from receiving stray signals
from another transmitter, or other source, and running out of
control. Your model has electronic fail-safes to prevent this type of
malfunction, but the first, best defense against a runaway model is
to always turn the transmitter on first and off last.
• Always turn on the transmitter before plugging in the battery.
• Always use new or freshly charged batteries for the radio system.
Weak batteries will limit the radio signal between the receiver and
the transmitter.
Loss of the radio signal can cause you to lose
control of your model.
Precautions
•
The High Speed dual-battery configuration is for high-speed
running on smooth surfaces only. Avoid repetitive hard
acceleration to prevent overstressing the motor, speed
control, and batteries.
•
Make certain both batteries are fully charged before
installing them in your model. Installing a fully charged pack
and a partially discharged pack may lead to overdischarging
and damage to the partially discharged battery.
•
Do not mix batteries of different brands, chemistries, or
capacities. Only genuine Traxxas batteries are approved for
dual-battery use in this model.
•
Stop running your model and allow it to cool if the speed
control’s thermal overload protection activates or if the
motor temperature exceeds 200°F.
When operating your model with two batteries, be careful
to monitor the temperature of the speed control and motor
to prevent overheating. Stop running your model and allow
it to cool if the speed control’s thermal overload protection
activates or if the motor temperature exceeds 200°F.
For best off-road handling with two battery packs, consider
installing stiffer springs on your model. Traxxas offers
accessory springs for this purpose; see the parts list included
with your model for part numbers.

If the status LED doesn’t light
green on the transmitter,
check the polarity of the
batteries. Check rechargeable
batteries for a full charge. If
you see any other flashing
signal from the LED, refer
to the chart on page 15 to
identify the code.
