Yep, I'm considering my charging choices now. I'm leaning towards having 3 inputs - Solar (already in place), Alternator (will likely need to upgrade to HO alternators) and House charger. I may add a dedicated charger just for this bank, and tap into the converter line going to the other charger. that way I can program this one for Lithium and leave the other for Flooded Lead. I will work on designing that part now that I have a source for the batteries and have that part of the equation done. Thanks again for the leads on the cells!If you have 12 of the 304 (might as well as about same price and size as the 280 Ah), you’ll have about 912 Ah nominal with 80% usable of 730 Ah.
The other thing you’ll have to consider is how to charge such a large battery bank. It could take 6-12 hours (assuming you have a 100A or so chager on your inverter) if fully depleted. A lot longer if all you have is something like the standard Pronautic that came with most Sea Rays.
Tom might have some input on charging these puppies up, but it is quite a change to go to high output alternators which would be my first choice.
