Also look into 3 cell LiPo batteries. Each cell makes about 3.7v fully charged and they are light but powerful. KSL might have some people selling the batteries and chargers for their RC cars and stuff. Ebay has crap loads of them too. Hobbyking has new that are pretty cheap. You'll be looking for 3C or 3S. That will power a fish finder for a long time and be light weight too.
