24v or 48v, Which way to go?!?

Yeah he does think that. And it’s supposedly true to a degree. But parallel connections are way less problematic than series. In either case, you should have an active balancer. Victron has one. I know nothing about them other than they’re pretty much essential if you have multiple batteries in series or parallel. It adds expense and complexity.

There may be some drawbacks to it but I think I had 2s7p with my 24v system for my old house and had no issues with it. This was with deep cycle lead acid batteries.
