Rubberized strap for attaching the battery to the frame. The strap is very durable thanks to the material used and the metal buckle. The metal buckle is entirely without weld. The strap is coated with rubber so that it does not slip on the battery and holds it firmly. The length of 25cm is especially suitable for 5″ freestyle and racing drones. The belt is 16mm wide so it can fit under 20x20mm stacks.
