You'll want something ~28mm thick or less if you want to easily use the stock battery bar. 25mm is the max without using spacers under the rear bar hold down and unscrewing the front a couple of turns.

The thickness I am not worried about so much. I am going to be fabricating two velcro straps into my stock battery tray and get rid of the battery hold down.
