I had seen those. I got excited (for other projects) until I saw that it had no communications capability.

a quick search I found this. never heard of this company but looks decent.

Thanks to many people for good references!

I hope you would agree that it is a clumsy patch to add BMS between the
UPS/Inverter and the battery.
But we have no choice.

Why has the industry stopped innovating?
I recently searched for inverters and/or UPSes, specifically looking for
LFP support - I have found nothing.
Why do we need to customize it ourselves?
I would not believe that product managers in APC (and many other vendors)
have missed the existence of LFP.
I did assume that any vendor not supporting LFP our days should go out of
the market very fast.
It looks like vendors are not developing anything because they are
preparing for an inevitable shutdown (losing market to well-known
competitors).
IMHO: vendors are accelerating their death in this way.

It may be some patent, but I doubt that a patent could completely block
innovations.

We're talking about stationery; it's not wearable, right?
Then there are many LiFePO batteries on the market.

Ummh, the Li in LiFePO4 (a.k.a LFP) is Lithium.

Li-Ion batteries come in all manner of chemistries, where different
materials may be chosen for the cathode. While there are a number of them,
the most common ones are NMC (Nickel Manganese Cobalt) and PO4 (Phosphate).

NMC has generally been used in EV's due to its high energy density, but
OEM's have now started moving to LFP for this, where LFP was traditionally
used for stationery applications (home backup, for
example) due its higher safety properties.

LFP is cheaper than NMC. And while NMC will provide fewer cycles than LFP,
the time period will vary based on usage, even with factoring in calendar
aging.

Mark.
