Best External Battery Solution for BMCC?

[/p/]

By best I mean the best compromise of power + size + price. Since I'm crazy I am using the BMCC in a documentary style (got it because I love the image it produces) trying to keep my gear down to an absolute minimum for portability and ease of use.. I need an external battery but I am not keen on the ones that attach directly to the camera (unless it's very small) I'd much prefer something that I could plug into the BMCC but attach to whatever I'v got the BMCC on, tripod, monopod or even myself. 

 

Thanks.

Switronix PB-70. It gives you more than 4 hours life on the BMCC. It's kinda heavy but it sits nicely on top of a tripod.  The weight actually works well because it acts as a counter weight for my shoulder rig.

Thanks. I am still looking for a good battery solution and have been looking at the PB70 like you recommended. What I am curious about though is the "regulator block" that comes with it, do you need to use that? The battery itself seems to have a P-tap is it possible to go strap from P-tap on the battery itself to the BMCC? I'd like a cable longer than 12' which the power block thing has.

 

Anyone know how the PB70 compares to other solutions? I'm looking at several batteries at the moment but can't make up my mind (unfortunately I'm not in the position to test them) I'm also unfamiliar with all of the brands since this isn't something I'v had to urilize before.

 

I will link to the batteries I'm trying to decide between, some of the ones I am trying to decide between are from IDX (IDX claim they partnered with Sanyo/Panasonic to develop theirs), Teradek and Lanparte, either because they've been recommended or I'v seen them being used in videos about the BMCC, they all have P-tap because I'd love to be able to go straight from the battery to the BMCC and keep it as simple as possible, I'm hoping with a solution like this I can get a small waist pouch and put the battery in it while having the cable running out the pouch to the BMCC which will be on top of a monopod so I can move around easily.

I just wish Sony v-mount batteries had P-tap.. I'd just buy one of those. If anyone knows of some sort of solution for Sony batteries I'd be interested to see what it is. Thanks.
