This tutorial will step you through the process of installing an XMOD EVO Poly Pro 2S Pack or the 2S2P Pack. Some of the Photos below were taken with the 2S Pack and others with the 2S2P pack. In my opinion the 2S2P Pack is a much better choice as it delivers twice the current and run time. This is a very simple process requiring only minor modification to the EVO and basic soldering skills.

1. XMOD Evo Lithium Polymer Pro Pack


2. Solder


3. Soldering Iron


4. Needle File Set


5. Hand Reamer


6. Hobby Knife Set


7. Side Cut Nippers


8. Phillips Screwdriver


9. Flat Screwdriver


10. XMOD Evolution Car or Truck

Remove the motor wires and pull them aside.

Take the Top Cover off by removing crystal and the screws holding it on.

Remove the two screws that secure the Stock Battery Tray.

You will need to pry the edge up with a flat screwdriver to remove it.

Remove the center MainBoard screw and the antenna screw.

Unsolder the factory battery wires. They are the largest red and black wires.

Remove the stock battery tray. Now face a trash container, take the Stock Battery Tray and hold it firmly in your hand, pull your arm back and then forwards rapidly. At the point that your arm can no longer travel in a forward motion, release your grip on the Stock Battery Tray, depositing it into the trash recepticle.

Now to the the next step.

We need to remove these pesky little tabs since they are in our way.

This is where the Side Cut Nippers come into play.

File the rough edges down with the flat needle file. If you don't have one of these handy Needle File Sets, you really need one. They come in handy very often.

Next you need to cut a hole in the Top Cover for the Board Harness to protrude through. Use your Hobby Knife for this operation.

Ream this hole out with a hand reamer. You can do this without a reamer but the reamer yields a nice round hole.

Make the hole large enough so you can just squeeze the Pro-Plug through the top cover as shown.

Lift the MainBoard up in the rear and rest it on the plastic tab as shown.

Apply a dollop of solder to each of the power input wire pads.

Solder the Board Harness as shown, with the positive on the drivers side. You want a slight tilt forwards.

This is what it should look like when you are done.

A closer look at the solder joints.

Put the MainBoard back in place and screw it down.

We now need to remove some material to make room for the Board Harness.

Cut from the center to the outside as shown using your Hobby Knife and then cut the resulting tabs off using your Side Cut Nippers.

Be very careful here, it is very easy to cut yourself. Remember to always cut away from yourself.

This is what it should look like when complete.

This is why you made the hole large enough for the Pro-Plug.

Now you can secure the top cover again.

You can now attach the Motor Wires again.

If it were me, I would be doing an EVO Motor Wire Upgrade here as well.

This is the antenna screw. Without the antenna to space it up it will protrude through the chassis like this. Be sure to back it out so that it does not stick into your battery pack.

Grab your EVO Poly Dual or Poly Quad Pro Kit.

Using the Hobby Knife lift the SuperStick Tape.

A note about this tape, it is very strong and will not come loose easily so make sure you get it right the first time.

Mount the batteries as far forward as possible while allowing room for the wires. The power wires will pass up through the passenger side wheel well with the 2S2P Pack and the driver side wheel well with the 2S Pack.

Here you can see the proper cell placement. Notice the amount of ground clearance you get with our Poly Pro Pack - 2S2P.

Very sexy!

With the harness plugged in you should have plenty of wheel clearance. This is the 2S Pack pictured, the harness for the 2S2P Pack will be on the passenger side.

Now slap the body on and go spank your friends, because you are done!
