There have been links to Lifepo4 batteries on this list that are effectively cheaper than lead acid when you consider you only need half the capacity. Also bigbattery.com just had some 36v packs that were incredibly cheap. I would check out those before buying lead acid.

20AH lead acid (which means 10AH of usable capacity) will run your motor at 1000 watts for maybe 20 minutes? Might be enough for your needs but stay far away from trouble (like a lee shore).Alright! I would need to double that then at least. But I'd have to plan so that I can start out with a smaller set of batteries in paralell 48v and be able to scale up from there.
Thanks for the link, it's a great resource. I wish I had a "sharp analytical approach" but realistically I have a "good enough" and learn-by-doing kind of approach.
