Exactly. I just received a the Trinity 4500 pack so I could check it out. When I finally received, the packaging looked fine but the pack itself had an impact hard enough to shatter the case on one side. Looking at the cells though (easy to do since there was a big chunk missing) it looked like no dents or punctures on the cells themselves. Now I'm a total klutz. I'm bound to drop a pack ( which is probably what Trinity's manufacturer did before packing mine
) and cause some damage. I don't think a soft pack would have survived this.
