Yeah, after looking at the 610i and the 1210i, I've decided on getting the 1210i. The 500w charging is neat, but also dumb. :) You can't charge a 12S brick with it, only 2 6S packs. Since I'm wanting to make the move to higher voltages, the cell count is more important to me.
If anyone wants to move their 1210i, I might be interested.....
