When my wife totaled my first Spark EV (well, she
had an accident, the insurance co
said it was a total loss) I almost, almost, almost bought it back just for the battery. I didn't only because :
- I didn't have solar at that time (although I was seriously tempted to change electric rates to get super cheap at night, fill the battery, then use during the day)
- I didn't have a place to 'temporarily' store the vehicle except my driveway, and I *knew* my wife wouldn't put up with that for more than a month or so (those who tinker know that 'time needed' is often "time you think it will take" times 10 or 20.
I still regret not buying it. It would have been a great 'spare battery'.
