Actually, the D200 battery does just fine for JPEG images on a D200, it's only when shooting NEF that performance drops. But Nikon says that battery life has been substantially improved on the D300, perhaps as much as double (after all, a CMOS sensor should be lower power than a CCD). But if that doesn't cut it for you, try this: get the MB-D10 grip and use the battery from the D2/D3 series, which has much more capacity. The more curious thing that isn't being discussed is why the switch from the EH-6 AC Adapter to the EH-5 or EH-5a? That seems like a decision that flies in the face of all the other good decisions Nikon made about compatibility.
This made me laugh so hard. Also, wtf? No ISO 100? Why? Just why?
