JT - the charger you have listed, when riding where do you stow this? I currently use the 'lunch box' method to hold the RA on a ram mount and connect by a 12v cigarette lighter socket zipped tied to the handlebars of the TTR.
Do you put the charger inside the box with the RA?
Also, in terms of connect, what cable do you run between the battery pack and the RA unit? Any pics?
