New powerwall 3 or used Tesla for storage

[Lonoxe]

Having joined Tomato energy with a 5p overnight rate, I’m seriously considering getting battery for energy storage but do not currently want to install solar panels. Considering 2 powerwall will cost about 17k and a usable used Tesla will cost around 20/25k with the addition benefit of driving it for school run etc, is that a better option is there something I’m obviously missing?

I dont think tesla currently support V2H. Unless you mean something else?
There is talk of this though.

Makes sense, I knew I must be overlooking something. Would be great is there’s a vehicle to home solution to maximise an EV use…
