16V Drag Racing starter batteries

[RJM]

Interesting topic-following. I am also at that "it's time" mark. I suppose it means a new smart charger, something that is on my radar. I do like the idea of smaller/less batteries. Right now I hate crawling around filling the batteries on my house bank. I am also thinking agm golf cart batteries. One way or another I am ready to say good-bye to those heavy Deka 8V's that I have.

There are these as well:

Seems like they might be a decent solution from a "specs" perspective, but not sure how they hold up in a marine environment or if the terminals will be HD enough

So wondering if anyone ever tried 16V batteries?
