Everything in life is an opt out model.

I'm going to quote you on my website unless you tell me not to.

I'm going to copy this music for my friend, unless you tell me not to.

I'm going to project a movie for my block party unless you tell me not to.

Recharge time is 8 hours with a 200-volt power source

Recharge time is dependent on amp-hours, not volts. If you hook up a 200 volt power source that can only deliver 1 amp, you are not going to charge your batteries in 8 hours because that is only 8 amp-hours.

I image that the car is designed around residential wiring, which is usually 12 gauge and rated at 20 amps, so in 8 hours you should get 8*20=160 amp-hours, which at the quoted 200 volts is 32kWatt-hours. Based on $0.10 per kWh, it should cost $3.20 per charge.

I forgot to add you can set the elk up to call your cell phone when the alarm goes off, and you can tie it into the smoke system as well. Now I know that when I get home my house hasn't burned down (we live in the woods, in what is considered Extreme Fire Danger).
