What can I use to keep battery in place

[buddymisty`]

My box has some extra space after installation and I wanted to know what is the best material to use that will keep the battery in place.

I hear some type of velcro would work.

I just use a thin piece of foam to stop battery rattle.

I used the foam out of a fullymax battery box it came in. Also have used the foam out of a DNA 200 retail box.

I use a small piece of 3M velcro.

I cut down some cheap pencil erasers, they are pennies from office supply stores.  You can get velcro battery strap kits form RC Hobby suppliers or eBay if you prefer, I would if I had a magnetic door.
