What’s the upside?
I got seven years out of a pair of group 29s Everstarts from Walmart,
just replaced for $90 each. And I just replaced the alternator on my
A4, which lasted 49 years.
But the way I use my boat doesn’t require having a state-of-the-art
battery system.
Cheers,
Randy

My batteries are about shot and I am thinking of going to lithium
batteries. I have to say I thought I knew this stuff and it seems
massively confusing with a ton of directly contradictory information.
One big issue seems that if the BMS disconnects for any reason, that
will do a lot of damage to your alternator and perhaps other
equipment too. Add to that my regulator does not have a specific
lithium setting, I would need to get into the custom menus and try
and make one.
What seems to be the best bet is just to connect the alternator to
the start battery and use a DC-DC charger to charge the lithium bank.
Some of them also take solar input, so that saves me buying a solar
controller with lithium settings, which is something else I don’t
currently have.
