Ideas for mounting A123 packs in Emaxx??

Ok, I know a bunch of you guys here run A123 packs in your Emaxx's. I am looking for suggestions and help on how to mount them in my truck.

I have a stock chassis, and plan on running two 5s packs in parallel. My DeWalt pack is still in the mail, so I haven't had a chance to play around with it myself.

For those who run A123 packs, can you please post pics of your setups, or throw some suggestions at me!

Thanks!!
