I'm wondering how to get setup for using the AeroVironment L3 charging station at the Fort Collins Museum of Discovery. Sites I found said to call the company at 888-833-2148 to setup up an account and the cost would be $3 per charge. However, when I called I was on hold for ten minutes and then talked to a person who seemed confused. They told me that it was $7.50 per charge and that I had to call each time I arrived at the charger and they would then activate it and charge me $7.50. Is this right?? Can't imaging that working. Anyone out there who can tell me what path to take to get set up for using this L3 charger?
