All this battery talk and talk of a battery standard that could be moved from tractor to car to house made me dig up this article I read about one month ago. This battery is not your usual external battery pack that you would use with your phone. It can power the authour's entire home office for 20 hours.
It weighs just under 40 pounds and costs a cool $1,900.

Higher voltage has a big advantage for the kind of power that's needed for electric cars. If you use higher voltage you can use smaller wires to move the current necessary to provide the power needed to move the vehicle. Volts x Amps = Watts (power) The size of wire you need depends on how many amps you're trying to squeeze through it. Higher voltage means fewer amps for the same power.
