Not everyone has a monohull, and most monohulls are designed to have their keel weight and depth work with all other design elements of the boat. So I doubt a heavier keel would improve performance, and would likely decrease it.

For a given design keel weight, it makes performance sense to put the weight as low as possible, on as high an aspect foil as possible. However, I don't think it would be practical to have batteries in a bulb on the end of a high-aspect foil.

I don't even thing it is practical to use lead batteries as primary ballast on a full-keel boat. What do you do when you need to replace them - tip over? And they would be experiencing a lot of tipping and forces when heeled - more so then if they were in the center of gravity.
