Simplyphi Batteries bought by Briggs and Stratton

I commissioned 3ea 3.8-48 in Dec 2020. I liked them immediately and added a 4th the following March. For our needs and power demands we are over batteried which is no problem with LFP04. They are filled daily in the winter** and rarely drop below 50%. There has been no noticeable change in performance over 4 years. There is no maintenance - not even to connections. Every few months I see them in the crouch space so I know they are still there.

As for warranty or customer service I've had zero contact or need to do so. As for setup I've stayed in contact with Raysun on the Outback Forum though we diverged on charging practices for a time. He has a really good relationship with some engineers at PHI and is kind of my PHI encyclopedia.

So Dave - I think you are asking about the B&S buy out or is it the batteries themselves? I tried to answer both within my experience.

** We are 85-100% dependent on generator charging in the winter so I adjust my charging practices to fill the PHIs to 100% SOC in case of a generator hiccup. That way I can easily run on batteries well into the 2nd day while I deal with any problem. During the long days of summer I dial back the charge voltage to ~90% SOC as I don't need the storage. I believe it will benefit me over time (I do a balancing full charge monthly when at the lower charge voltage).

I hope these batteries will outlive me. That was the reason I watched and watched before I took the massive $ leap. It was well worth it. If something happens to me the most maintenance intensive (and dangerous) part of an off grid system is the batteries. That subject is off the table. Whatever charging practice is in place when I choke the wife will have no problem continuing. Sound fatalistic and gross? I don't think people give this topic enough attention.

And so, so many undocumented systems with no history. And a person assumes it, whether they are technical or not. What a mess. Especially for the family running blow driers.
