I am suspecting Emery you are looking to help save some hull weight ? But before looking to save weight (shave a few pounds) on batteries I would make sure you read the 4 paragraph in this article http://www.odysseysoutheast.com/odys...-batteries.php on battery construction first

Maybe using a smaller group size battery of higher quality to help reduce weight would be another path to consider

I know those Odyssey PC1200 batteries I have are not light by any means for their group size, but they are very well built unit and I have never had a moments trouble either starting or with my trolling motor since installing them
