Hi Eric,
I'll try to put together a quick, down and dirty, 2.1 volt unit and see if I can give some numbers that will show what is going in and out, as well as surface preparation of the lead.
The East Coast, might interrupt things depending on what happens.
Also I will try and post a picture or two of motors, batteries and inverters, that some, might find useful, especially in smaller boats.

My testing has been lead strips in a jar of acid, a small and quick charge, then an equally short motor run. The lead and acid have set for several years and have had no decay of either. I do tend to favor other less risky things to play with. :)
