Moving from the HVRZ1U to the XDHDCam makes great sense but I am worried about the battery situation with flying every week for months in a row. With the small L type batteries of the Z1U you can get away with bringing 3 of them which last way longer than the IDX type L-Ion we would be using with the XDHD cam. What are those of you doing that travel every week to remote locations doing concerning battery power. I just dont see 3 IDX L-ion batteries getting the job done when you need one to run a camera light and one to run the camera and one spare. Shooting an average of 12 hours a day of footage on 3 HVRZ1U batteries is pushing the envelope and know 3 IDX L-ion batteries are not going to make it for that amount of time. I know people are Fed-Xing batteries to there locations and then Fed-Xing them back home when finished but surely there is either a better longer lasting battery or an easier more economical way then mailing your batteries. Would hate to buy new IDX batteries since we have dozens of them. Any suggestions.

Did a little digging today concerning my thoughts on IDX L-Ion batteries and found out those batteries are not over 8 grams of Lithium content so In a carry on bag I could attach 1 battery and also bring as many 8 gram or under batteries as I would need (no limit) but could only bring 2 batteries with gram counts over 25 grams. Was surprised to see this new info, it seems they must have done some revisions to the law in the last few months.

There's very few Li-ion batteries with over 25 grams of Lithium. I regularly fly (US and Europe) with 3 DSM 98 W/hr batts in my carry-on. These give me about 2.5 hours of continuous use each which I find is enough for an average days shoot. I also pack a swit dual channel charger so I can re-charge 2 batts at a time.
