Finally got a chance (excuse?) to try my new Dinotte 200L tonight---just 3 miles zipping around the neighborhood. Love it! I'm not a fast rider, so can't imagine outrunning the beam. Combined with my usual blinkies and tail light, it's definitely a winner!........Those of you who have the AA version, do you charge up the batteries and store them in the battery holder (disconnected from the light) until use? Or is there a good reason not to store them in the battery holder, e.g. reduces battery life? From what I've read, the newest NiMH batteries hold their charge pretty well between uses.
