I do not have any EV's. Yep with EV's, ev2-a is the way to go, and cycling batteries would be a cake walk. Just not what I have.Also, h2of, I didn't see whether you have an EV. I have three PWs and two EVs (a Model 3 and eGolf).
Since the car capacity is 100Kwh and the batteries are only 40, given some reasonable amount of driving I can cycle them easily.
Without EVs 65Kwh of PWs is not as easy to cycle.
You could also spend a couple thou on an electrically heated jacuzzi. That would solve it.
I have one of those as well. Ha!
