Wow. That'll outlast you! :-)

The pack I built is just over 30 watt-hours. But it's also powering the wireless receivers. The Li65S might be just a little too big to fit my own application but the price per watt is hard to beat. Thanks for the link!

Final update on the battery; 15 hours of recording, then the card was full, and I was out, but when I came home (about 5 hours later the R44 was still on and the battery gave me 1 LED...

The battery pack also powers a pair of Audio-Technica ATW-1800 wireless receivers for four independent channels of audio. Runs 4 hours at a stretch.
Very cool set up Dean. Can't imagine they'd ever let you in to an airport with it though, looks like a bomb!

It's the Audio-Technica ATW-1800. Each receiver has two bodypacks. And I'm using the AT 899CW mics, not the stock mics.

Dean,

That's a cool set-up. On the AT899c lav, do you find yourself using the vampire clip much or something else out of the included accessory kit?

Guy...

I haven't used the vampire clip.

I shoot a lot of people wearing t-shirts and modified the standard alligator clip to hold the mic capsule about an inch below the shirt's knit collar. The only thing showing is part of the clip.

Sometimes I'll tape the mic capsule under the edge of a piece of clothing, just out of sight.

I find the 899's vampire clip usually creates a noticeable lump under clothing. I use a cable clip vampire from a deceased Tram or Sonotrim.

How did you do it?

Hey Vincent great posts. My setup for use is actually getting really close to your own, except I'm using the 5D MKII. I was originally using with DV/HDV gear. I'm lucky that I have been able to survive on batteries. More typically, I am able to just plug it into AC. However, I do like to be prepared. So you lost me at D-Tap. Do you have to modify a cable or were you able to use a cable meant for something else that happen to work with the battery and recorder? Battery power is the one area that I know nothing. Most other equipment I have been able to hold my own but this topic I go blank.

BTW Dean, stop scaring the children! That picture is more than just impressive. The right angle connectors alone look like they should be hooked up to scuba gear. We often make our own props from everyday gear that most people don't typically see. Your pack would easy make off as a bomb, seismic gear, or modern ghost busting equipment

Hello Vincent,
That's a great resource for batteries. I looked on the site and couldn't seem to find the mounting hardware to interface the battery to the gear. Its a V mount isn't it? Did you get that from somewhere else or is it on their site somewhere?
Thanks,
Bernie

Hi Bernie and Thomas, Yes, it's a V mount battery but I actually do not use the v-mount, but the D-tap connector output. An industries standard on pro- broadcast cams for accessories like camera lights. I made myself a cable for it, a bit like this pic shows:

Off course you can use the V mount connector with a baseplate like this one for about 30 euro's:

Globalmediapro VLP-1 V-Lock Mount Plate

You do have to solder a connector on it which matches with the R44.

I decided to go with the first solution since it's less bulky.

Since Im really interested in the Edirol, Id like to update this thread if possible: How are you guys getting along with the 44? I want to use it like an SD mixer as the sound solution for 5D shoots.
Did you find a good bag for the Edirol?

And does anyone know why the price of the unit went up about 100? Did that happen in the US too?

Thanks guys!
