So I need the absolute most powerful internal battery for it not external cause I'm already runnin an amp. Thanks a million
Not sure what battery you have tried but here is one you may want to take a look. In addition to replacing the battery, I strongly suggest you to consider swapping the stock HDD for a 32GB CF card using the Tarkan adapter. From my experience, this swap will greatly improve the battery performance. The ipod will be much lighter and boots noticeably faster as well. CF card will be also more reliable than the stock HDD as it has no moving mechanical parts. If you need more storage, consider 64GB or even 128GB instead of 32GB CF card.

My understanding the battery for the 5.5g/80GB is different from the 5.5g/30GB. I also notice the 5.5g/80GB stock battery has performed much better than the stock one for the 30GB model.
