    New Rustler & Lipo

    How do you make a 2s lipo battery fit in the Rustler Model# 37054-4 ?
    The battery is too long for the compartment on the Rustler.

    What am I missing?

    Your not missing anything, you simply have the wrong size battery. If you are okay with a little modification you can cut out the rear part in the battery tray to gain an extra inch or so

    Thank you.. I will look in to that right now.
    But why would a Traxxas battery not be the right size anyways?

    New Rustler & Lipo

    Because it is made for a different vehicle. There are correctly sized Traxxas batteries for the Rustler. Did you buy the truck and battery together as a “combo pack”?

    Different sized vehicles have different sized battery compartments. A larger truck will be able to fit a larger battery. You have the larger battery. The part number for the Traxxas battery you need is 2843x.

    If you go to the traxxas home page click parts and accessories and click battery finder on the next page top left corner. It will give you all the traxxas recommended batteries and chargers for that model. If you buy a 3s lipo (the big block batteries 2843x and 2845x) you will need part 3725x to fit the battery under the esc. Once you find the battery you want you can use that part number to buy it anywhere else (amazon or other sites) and still get a battery that fits your car..
