Will the battery die before it fills a 16gb card when shooting video?

Have you seen the lower price of Lexar SDHC class 10? Don't know if I should get the 16gb or the 32gb.

Depends.

A 16gb card will shoot about 2 hours of video...

A stock Panasonic battery will shoot about 2 hours of video, provided you don't use much autofocus, OIS, or LCD. Any of these, especially OIS, decreases the battery duration.

Thanks Kevin

I guess I will order the 16GB cards then.
