Thanks Jim,
I am aware of the internal resistance, but had not given it much consideration in relation to cause and effect. I'll keep that in mind and learn just how much it needs to be factored in to the configuration and spacing of the lead media in my design proposal.
My early thoughts were in design of stainless steel screen mesh in circular flat disc plates, dip coated in molten lead and having a certain thickness for extended wear. The positive & negative disc would be allowed a slight freedom of movement and separated by non-conductive thin poly pad having bristles of some amount of stiffness, a cleaning action could take place. Internal cam bars fixed at 180 degree spacing would hold all positive plates up, while all negative plates are allowed to drop to the wall of the round battery case. I do have all (I think) insulation and spacers figured out, that would allow this type design to be built in whatever length PVC pipe needed, limited only by voltage, what is practical to handle physically or design setting within a boat hull.
Don't lose sight of what my thoughts are proposing here, this is focused on a more massive weight serving, as ballast, and at the same time a somewhat compromised energy density and cold cranking amp discharge capacity battery system.
The true value is a system of storage that should have a long life and very easy to recondition in a very simple work area, even at sea if need be.
I feel that pride and somewhat misinforming sales pitches in most areas of electric energy storage and use, have blinded most people from thinking and really understanding the simplicity of the basic mechanics, needs and use.
By no means do I want to belittle the engineering progress to date, I just think we need to be careful not to perfect ourselves out of, affordable and enjoyable products.
