It was last year, I was shooting canon, using a 30D

You can get "digital camera battery" from many sources including this link http://www.bhphotovideo.com/c/product/41...ttery_Pack.html

There are many models, I used the 40W model. If traveling overseas, get the proper charger, the 110V charger will not work with an inverter.

I did not look to see if they have cables for the new D300, if not, they should soon

I found the "DCB" much better with the cold than Quantum and other brands.

Thanks for that, I was considering the new quantum turbo but will look into the one's you posted. . .

Thanks again,

I have not reviewed the new turbo but was happy with the DCB

I own the digital camera battery as well. It is a great product - though if I did it again, I would get the smallest one available these days. I was able to run the flash off the battery for an entire wedding back in the days where I used a lot of flash to do my work. The extra weight does get irritating after a couple of hours.
