i have a ford mustang mach-e with 100kWh. But i did wrote in my original comment, that mine can't do the bi directional yet, but its not a phsyical issue.

yes of course. With one discarge cycle for a day or two, i still have 998 left.

Only if you actually believe my Batterie has only 1000 cycles.

You can easily charge and discharge EV Batteries a lot more times if you do it slow and controlled. 1000 also only means reduction of load to 80% (in theory/worst case).

And no i'm not doing this for $2, i would assume that i would consume 50kWh per day for heating, which is already nearly $20 and its about grid stability.
