For our first ever injection-molded part, we chose our popular Low CG Battery Tray for the Traxxas TRX-4. This part is injection molded in a highly durable nylon compound with a matte finish, and it includes slots for standard velcro battery straps so that you can secure your pack. This combo includes our XL rear chassis brace, allowing you to run packs up to 158mm long without modification.

More about the battery tray:
Using 3D imaging technology, we've taken full advantage of nearly every available cubic millimeter to lower the battery tray floor, lowering the center of gravity and making more room for more packs of different shapes and sizes. Our battery tray allows packs up to 53mm between the side walls and up to 158mm long when used with our XL rear chassis brace. That's long enough for most 2S and 3S hard and soft packs like the Helios RC 6000 mAh 100C pack shown in the pictures above.
