That's exactly what I did as well. But I made a last minute change the night before and shifted the battery as far forward as possible and forgot to move my "foam stopper".

Another thing that can be done is to make a battery tray out of light ply, attach some sticky back velcro to it, glue down a regular velcro strap, and then glue the tray down inside the battery compartment. Then attach the other part of the sticky velcro to the battery. When the battery is mounted, the battery is then velcroed to the tray and then the strap is tightened down over it. This is how we secure our batteries in our helicopters and I have yet to throw a battery during very rapid pirouettes or during a crash. This is how I'm going to secure the battery on the next build!
