Traxxas stampede retailer lot

Product Name: Traxxas stampede retailer lot
So I got this from a friend and never figured everything out with it. I have atleast two engines and one in the box several battery packs and a charger. The remote box and manuals along with another set of Traxxas tires and shocks springs ect... This is a ton of Traxxas stuff and I have no idea if any of it goes with this set or not really this is for someone who has a solid setup and wants to get a bunch of spare parts (a ton are still unopened) but to be fair I don't know what works and doesn't. The remote powers up and the truck turns on but that's the extent of my knowledge. I know what some of these parts retail for and just between the two engines and the truck it's over 600 in stuff all the other gear I have no idea on and still think there is atleast retailer one more engine in there. Feel free to make me an offer.
