What are the differences. I was unable to find anything on hear or YouTube that talks about the differences between the revisions. It appears that only the Rev-2 is available on the CountyComm website.
Where can one get rev. 3 copper versions of the AAA and CR123?
No rev3 out there yet for any copper versions. AA and AAA are both at Rev 2, and CR123 is still Rev 1. whenever CountyComm gets something new in, their "What's New" page is updated. New stuff comes in at the top of the page...
I recently got both the rev 2 and the rev 3 versions of the Maratac AAA, both of which are black anodized aluminium. The only external difference between the two is the GITD o-ring on the rev 3. Nascar, I think you will really like the Maratac AAA rev 3. It isn't any bigger than your E01, and serves well in the keychain role. However, it does not come with a split ring, so you'll have to cope with that.
You must be using alkalines. Switch to Eneloops and you won't have to worry about squeezing every bit of energy out of them, just recharge. You also won't have to worry about leaks.
