INSTALLING TRANSMITTER BATTERIES
Your TQi transmitter uses 4 AA batteries. The battery compartment
is located in the base of the transmitter.
1. Remove the battery compartment door by pressing the tab and
sliding the door open.
2. Install the batteries in the correct orientation, as indicated in the
battery compartment.
3. Reinstall the battery compartment door and snap it closed.
4. Turn on the transmitter and check the status LED for a solid green
light.
If the status LED flashes red, the transmitter
batteries may be weak, discharged, or possibly
installed incorrectly. Replace with new batteries.
The status LED does not indicate the charge
level of the battery pack installed in the
model. Refer to the troubleshooting section on page 31 for more
information on the transmitter status LED codes.
SELECTING BATTERIES FOR YOUR MODEL
Your model does not include batteries or a charger. Two identical
Lithium Polymer (LiPo) batteries equipped with Traxxas iD® High-
Current Connectors are required. Do not use Nickel Metal Hydride
(NiMH) batteries. Traxxas Power Cell iD batteries are strongly
recommended for maximum performance and safer charging.
The following chart lists the available Power Cell batteries for
your model:
LiPo Batteries with iD
2872X
2857X
2889X
4 AA Alkaline
2890X
*Requires additional battery pack spacers for proper fitment (part #7819, sold separately).
Note: When operating the XRT Ultimate with 4s LiPo batteries and
stock gearing, the top speed is 50+mph. 2s/3s LiPo performance
will be much slower.
MUST use a LiPo balance charger for LiPo batteries or battery
damage with the potential for fire will result.
DO NOT use NiMH batteries
with the VXL-8s electronic
speed control. The batteries
will become extremely hot and
damage or injury could occur.
SELECTING A CHARGER FOR YOUR MODEL
Make certain you choose the correct type of charger for the
batteries you select. Traxxas recommends you choose a genuine
Traxxas EZ-Peak iD charger for safer charging and maximum
battery life and performance.

Use the Right Batteries
Your transmitter uses AA
batteries. Use new alkaline
batteries (part #2914). Do not
use rechargeable AA batteries
to power the TQi transmitter,
as they will not provide
sufficient voltage for optimum
transmitter performance.
Caution: Discontinue running
your model at the first sign of
weak batteries (flashing red
light on the transmitter) to
avoid losing control.
If the status LED doesn't light
green, check the polarity of
the batteries. If you see any
other flashing signal from the
LED, refer to the chart on page
31 to identify the code.
