Any advice for taping batteries into the RDX? I've got what I think is the latest revision of the 2.9 chassis, and it's got slots cut in it near the battery posts, but they're pretty narrow. Is there some special narrow tape that people use for this, or should I look into getting the new chassis with the wider slots? I can't really find a good way to mount the Orion Carbon battery in my car without tightening the strap quite a bit and tweaking the chassis.
