On my first time around.... I used an 8D truck battery as my anchor, and 16/2 marine wire instead of anchor chain. This had the advantages of some chafe protection without having to use chain. True, the lights were dim when I used all 400' of my rode, but I saved a lot of weight this way.
The second time around I used a battery keel. It work well until I ran aground one night on a submerged sewage pipe. Believe me, the sparks and the sh!t were really flying.
