oobflyer, Terry Hershner has found that fast charging has little effect on the batteries and that keeping them at a high state of charge has a greater effect. He has only quick charged his batteries for more than 50,000 miles and they still hold a full charge.
The J1772 connection for this setup would need to be purchased through Hollywood Electrics since the connection is different from the plug on the motorcycle.
I used this setup to ride 250 miles in one day with 3 stops for charging a few weeks ago. Riding time and charging time were both about 4.5 hours on a beautiful day. I regularly go up to Bear Mountain and ride 50 miles to get there, charge up while eating, then ride through the state park, charge for an hour, and get home. They definitely give me more freedom!
