Are you talking about a Monster Truck? In a buggy/truggy the is usualy only two body clips so you can lift one side of the body up withour removing it (your body might not last as long with the constant bending) then it is just a simple case of removing the battery and re-pluging it in. If you only use one velcro strap and use bannana plugs instead of deans i would have thought you could change the batteries very quickly. You could tape/glue the two bannana plugs together to make the changes even quicker.

If you really wanted and you were using ideally a hard case Lipo you could attach the two female plugs to the side of the Lipo and attache the male plugs to the battery tray so that all you have to do is lift the battery in and out.
