They seem to be  the most suitable batteries at present for home energy storage  with long life and reasonable cost but presently only seem to be popular in the Southern Hemisphere.   However a Dutch company  is making a  Tesla like battery pack.

I had in mind to use day night to day storage  to use the system all year and to add PV later.    PV is not feasible in Ireland without batteries and it doesn't seem to be going to change any time soon.

RS have small ones. They're mechanically fragile.

The price is probably quite high, they don't quote prices yet,  but it seems to be getting a  bit closer to a practical solution.  A packaged system is probably a lot easier to manage   but the Tesla and others don't make economic sense  even when used constantly.  The LC batteries apparently can be damaged by  rough handling but that shouldn't be a problem for a static system.
