Premium lipo battery straps made by Scorpion Performance. These patented 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 "medium" size straps are 220mm long and this kit includes 3 straps. Two options for the strap appearance, there is the Lumenier logo lipo strap and the FPV Manuals logo.
