Although you might get temperature stability, would it be healthy for the batteries? Maybe they work better at 75F than say 50F.

50F should be enough, and will quickly hit ideal temperatures as it heats itself while working.

A stable 75F might be better but I'd rather have stable 50F over unstable 75F.

My car heats its battery below 60F, and it takes about 10 minutes.

A car needs to be ready to discharge at a much higher C than a house battery. So letting the house battery get a bit colder is fine.

Many electric cars have limitations on acceleration when the battery is cold.

Yes, I know.

My whole point is that cars are more demanding than houses.

So the house battery can tolerate a moderately lower temperature while meeting baseline performance.
