The Lumenier branded small Velcro Lipo Strap is made by Scorpion Performance. These patented lipo battery straps are rubberized on the side facing the lipo which ensures the lipo can't slip out, even without any additional velcro applied to the lipo and frame. In our opinion, these are by far the best performing lipo straps that secure your lipo and enable a quick lipo change. These "small" size straps are 180mm long and 15mm wide --- this kit includes 3 straps. These are skinnier than the medium sized straps, great for applications where a larger strap won't fit.
