Already available for the iPod nano
, Battery-Biz is rolling out their Duracell PowerFM line to the iPod Video, complete with FM transmitter, extended battery, and bonus protective silicon case. The extended battery more than doubles the iPod's run-time while powering the FM transmitter, with unlimited channel selection. It also replicates the iPod's dock connector, so you can still use all those other accessories without unplugging your 'Pod. No date yet (they're saying end of Q1, early Q2) but expect a retail price of $79.99.
