Best portable power option for amplifier board? Answered

I plan on modifying an old bookshelf speaker into a self-powered speaker with iPod Dock, radio and 3.5mm inputs.

I have pretty much all of the plans down, but I don't know what would be the best RECHARGABLE power option to use. (That's where you come in :3)

I will be using this (http://www.ebay.ca/itm/251137327317?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2648) amplifier board, and it will probably not be used too much (Camping mostly. No more than a few hours a day, and there is electricity on site if needed).
