I've read quite a bit about not skimping on battery straps, pads, or anything else that keeps your packs in place while you're ripping your quad around. One bit is an insistence that there be some form of grippy or sticky surface. These straps not only don't have that, they are made of common nylon strap material that actually feels slippery. If it would be worth it, I'd return them for that reason alone. Maybe they're tough, durable, whatever, but I'll likely never know because I doubt I'll use them--unless I figure out a mod to give them some grip.
