While I was vague and only stated “Li ion” I definitely have no fixed start point, so this is all good to learn about. And certainly echo Busby that one needs to consider weight for ballast purposes as well. I’ve spent most of my life around airplanes, so a slightly different approach to weight reveals itself, though CG management is a common theme here.<div><br></div><div>Thanks to all for the info and discussion.<br><div><br><blockquote type="cite"><div>On Jun 3, 2023, at 7:51 PM, Michael Holt via Personal_Submersibles <personal_submersibles@psubs.org> wrote:</div><br class="Apple-interchange-newline"><div>

I was sent some <i>Waterways World</i> magazines from 2020, a
couple of years ago. There are advertisements for electric power
systems for canal boats. They start with diesels tied to generators
tied to batteries that drive 48VDC motors. There appear to be
versions that have no diesels involved, and the batteries are
recharged from shore power. In the UK, that's 230VAC.<br>
<br>
If anyone's interested, I'll dig out the magazines and make a list
of the websites.<br>
