Perhaps you should be offering the choice of using the Velcro mounting shown in the pix along with another Velcro strap around the battery . I find that flying the multi rotors in any aggresive manner will dislodge the setup you show . hbatteries shift in flight . Having the second strap around the battery solves this problem and prevents crashes by the shifting CG .

For your poll , LOOP on the battery . (the fuzzier one)
