Sgt: I measured mine at about 10mm. still pretty shallow by any measurement.
Steve_S: beefy cells aren't they ! I know you'll like them. in case you're interested I got 5' of 1" copper bar stock (5 12" pieces) which I made in to some nice bus bars. It was better than beating on copper pipe. Not too bad of a price for solid copper.
