Both my big batts are 1300, and I am happy with them. At some point, though, I'm thinking I want to get the 650 models, just to see. Especially for the DAV for a shorter charging time. After which, maybe I get the mid models.
There's 3 sizes for the Zeus, with 2 modes. 6 batts. 4 sizes for the DAV, also with 2 modes. 8 batts.
I'm actually using the dual mode Zeus in manual all the time, and the DAV's auto. Still haven't decided which mode I prefer. :s
All in all 14 batts. :s
