Installing Battery Packs
The E-Maxx requires two fully charged 7.2 or 8.4-volt (stick style)
NiMH battery packs. These batteries are not included with the
model. For the best performance, use 7-cell battery packs. When
using 6-cell battery packs, install the supplied foam block (spacer)
into the front of the battery compartment. The spacers are located
in your instructions package. The spacers are shaped to conform
to the chassis. There is a right and a left. Test fit them to confirm
their location. Remove the backing from the self adhesive strips and
secure them to the front of the battery compartments.
Using Different Battery Configurations
The battery hold-downs are
capable of accommodating
either side-by-side racing
style packs or the more
common stick packs. The
battery compartments
are configured for stick
packs from the factory.
The number on each
side of the hold down
indicates the battery
height in millimeters
that hold-down can
accommodate. Note that one side is labeled “25” and other side is
labeled “23”. The 25mm side is for use with typical stick type battery
packs. If you are using side-by-side racing packs, simply flip the hold-
down over to the 23mm side and use it on the opposite side of the
chassis. Accessory hold downs and foam (part #3927X) are available to
accommodate larger battery packs. See the 3905 E-Maxx parts list for
more information.
Battery Installation
1. Remove the battery hold-
down by pressing on the
release tab and lifting out
the hold-down.
2. Install the battery pack with
the battery wires facing
the rear of the model. Your
model includes foam blocks
which should be installed
behind 6-cell batteries for a
more secure fit.
3. Insert the tabs of the battery
hold-down into the slots in
the rear hold-down retainer
(A). Swing the battery hold
down towards the chassis
and snap (lock) the end into the front hold-down retainer (B).
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 the EVX-2. 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
on page 13 for packages available from your hobby dealer.
The typical Molex style connector is inadequate for
use in your model. It creates resistance that becomes
a bottleneck to current flow. If your battery pack
is equipped with a Molex connector, it must be
replaced with a Traxxas High-Current Connector to
mate with the EVX-2 electronic speed control.
Use the Right Charger
The most convenient type
of charger is an AC peak-
detecting charger that plugs
directly into an AC wall
outlet. It contains special
peak-detection circuitry
that automatically shuts the
charger off when the battery
is fully charged.
If you’re using a 15-minute
timed charger, always fully
discharge the battery pack
before each charge. Some
high mAh battery packs
(1500 mAh or higher) require
more than the standard 15
minutes of charge time. If
the battery pack is cold after
15 minutes of charging,
add another 5 minutes of
charge time. Closely monitor
the battery pack and stop
charging it when it begins
to feel warm to the touch.
Never leave a battery
charging unattended.
Always follow charger
manufacturer’s instructions.
Warning: Lithium Polymer
(LiPo) batteries should not
be used with the EVX-2. The
EVX-2 is not equipped with
low-voltage detection.
