Doubble Gen 2 Battery Life?

I'm not sure how the charging works, but it might not charge up properly, it might only charge it up to a certain numerical amount, not percentage, also, I'm not sure how having 2x the battery would affect things like the power meter. You should inquire to people who have the external battery pack and find out how the ipod handles it (I know this is availible on the new iPods, not sure about the old ones).

Before you go hacking up your iPod, you should :

1) wait until your warranty is over (as opening your ipod will kill any warranty you have)

2) check it out online (ex: (http://macfannet.mycom.co.jp/special/ipod_barashi/011031ipod_barashi.html = pics of the inside), just did a quick google search, I'm sure there's better out there

And I wouldn't even think about trying to fit the second battery inside the case, that is unless you want your iPod to be held together using duct tape or something. True, there is a certain amount of class that comes with keeping things together with duct tape, but I really don't think its worth it. Keeping the battery outside and just having wires run in really seems like the best way to go about this. If you use a leather case, or the apple carrying case, you should be fine, but you may want to wrap the battery in something so it doesn't scratch the outside of your pod.

Also, if you're forced to use tape for any reason (you may want to just tape the battery to the back of your pod), don't use duct tape. :D

well if you've get the paper in there might as well wire up the battery and slap it in the case. Becareful not to hurt yourself, and let us know how it goes.
