Lithium is an interesting option, isn’t it? About quarter of the weight. You need about half of the Ah capacity (since you can go from 20-100%, instead of 50-80%) and your bulk charging can get you to 100%. But you need some sophisticated charging and controlling circuitry.
I am not sure if we are there (for the cost and reliability), but we are getting close.

A boater on my dock is in process of installing 4 of them on his O’Day. Cost of the batteries is about $300 each – which isn’t dramatically higher than good AGMs, His bank will be between 400 and 500 AH (I forget exactly what he told me), but with Lithium batteries you can use more than 50% of the bank capacity without harming the batteries… you just need the correct charge profile (and a higher capacity charger).
