If you're going to send it, you want to make sure that you batteries aren't going anywhere.  That's why our 225mm Non-Slip Battery Straps (measured from plastic loop to the beginning of the hook section of the strap) have a non-slip coating to help keep your batteries securely in place. These are sold in pairs and sized specifically to work in Arrma 1/10th scale vehicles like the Granite, Big Rock, Senton and Typhon, as well as many other surface and air applications.  So strap in and let her rip!
