With the Diehard battery and the H-D rectifier I am running a solid 14.4 volts at speed. I use the JW Speaker LED headlamps and with them on at speed I get 14.3 volts. I double checked with my ammeter for confirmation and everything is dead on.
What's your mileage? Who cares. Is it practical? See #1. What happens when it rains? You get wet.
