Not finding the definitive thread, if someone could point me there.....
Just considering a 702, but wanted to get the full powering scoop first. Is the internal worthless? Does a standard dvd battery work?

People use "L" type camcorder batteries as well as externals using the Hirose connector to whatever they've got. The externals need to output 12V. The L batteries are 7.2V. You can also make a "dummy" cell and wire that up to RC 7.2V battery packs as well.

I just picked up a pair of these; they're 7800 mAh. Road testing them this week, but appear to get good reviews, and they're half as much as Sonys.

Thanks!

Another option for the L-series battery replacement is the Lenmar LIS970P. I've had my 722 since initial release and have had great success with the Lenmar brand. They've always proven to be super-reliable.

I notice the Lenmar has a three year warranty vs only one year for the Watson. Plus it's cheaper. Looks like Lenmar is the better deal.

Thanks!
Do I need a power cable other than what comes in the 722 box to use the Lenmar battery?
-
This battery slides into the back of the unit. No cables.

Definitely a nice deal on the Lenmar. I especially like the dual bay charger:

I only use these batteries in my 702. Never saw a reason to go external or dummy battery.

Stay away from these batteries. I got one good and two bad.

Again, I suggest the Lenmar LIS970P. As long as you don't deeply discharge them regularly, 2 of them should get you through a typical day of festival recording 2 chan w/ +48 and meters on full during daylight gradually turning down brightness as sunlight wanes. Although I usually carry a 3rd as a safety and change 'em more often than I should to avoid discharging too deeply and extending overall battery longevity...
Have a 2nd set x3 charged for day 2 while the 1st set of 3 are charging. Lather, rinse, repeat.
FYI, I'm running a 722 recording to HDD+CF @ 24/48 and transfer from CF>card reader>PC and have *never* had the 722 fuck up where I need to transfer from HDD (other than human error). But it sure is nice to have a safety copy.
Battery life is much better when running just to CF and not powering the HDD in the 722. I'm just a paranoid freak and like having the safety track...

wasabi 8500 mah battery for $39.99 with free shipping. Good reviews on Amazon. There's also a two battery and charger deal for $84.00.
I haven't personally used this battery, however.

That's what I got as a replacement. Seems solid.

It is a solid solution. Smart, easy choice, IMHE...

I've always been curious why the internal battery is 7.2v but the hirose connection is 10-18v? Why is that?

I'm curious about this as well.
Not only why the batteries are 7.2V and they hirose is 10-18v, but why the 8V range? Will the unit work equally as well on 10V vs. 18V?
-
I could have sworn that in order to run an external FW drive (ie DVD-RAM, or HDD) you had to run external power and this was one of the reason of the higher voltages
Also if the battery can be charged via the unit through external power that would also hint at the higher voltage
