This owner of a Porsche 928 has turned it into an EV. Nice job!
McCabe originally installed lead-acid batteries that gave a range of 40-45 miles. Those have now been replaced with 750 lithium iron-phosphate cells arranged in series and parallel to give 160 volts and 25 kilowatt-hours of capacity. The electric 928 can now go about 115-120 miles with a top speed of 85 miles per hour. The speed limitation is due to the fact that first, fourth and fifth gears were dispensed with in the name of mass reduction.
