Following the spirit of the more advanced theme of Architeuthis' post, I often think that there's a place onboard for Edison batteries as part of the total capacity on board. Yes, they lose 1% of their capacity every day (and DON'T EVER OVERCHARGE THEM), but they last virtually forever. There are Edison batteries that are 50 years old still working perfectly.
The way to do it would be to figure out your daily usage, the amount you draw down on your lead-acid batteries each day. Then use Edison batteries for that load and keep your lead-acid batteries protected from any discharge cycles on typical days. The lead-acid batteries will last for decades, depending on how much you do draw them down. And since only the typically-used portion of your bank is Edison batteries, you won't be appreciably impacted by the 1% loss per day drawback.
Edison batteries are what the WWII subs used to provide power when underwater. They were also used by railroads.
Great minds discuss ideas;
Average minds discuss events;
Small minds discuss people.
The best minds discuss sailing (and a little bit of politics). I don't know why. It's a mystery!
