Removing the main battery from a camera is not a good idea at all. I t means that the backup battery, which also keeps the internal clock going, gets drained much faster, and that is both harder to change as harder to obtain, and is not rechargeable.
With PDAs/cell phones this battery gets drained well within three days, generally speaking, when the things is not in use, so I would not risk this from happening.
I have similar experiences with ring/macro flashes, with regards to the battery drainage, including those with in-built Li-Ion batteries, with the exception of my old Cokin Creative Flash set. That is the only one that doesn't do that, and is by far the cheapest I ever got (50 euros used <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='B)' />). The hot shoe flashes (430, 580) don't drain batteries, fortunately, when switched off <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='B)' />.
Kind regards, Wim
