"CC" series connection cables (modules) are the shorter version of the standard cables, and will work with any Turbo series battery pack. They are only 1.5' (.5 m) long, and prevent tangled cables.
Note:
To use a Turbo-type battery pack with the Canon 580EX II flash, you will have to disable Flash Custom Function #01 on the flash.
