El pollo yes I understand that a capacitor could replace a battery but not sure if the five wire trailtech really would like that seeing the ability of a capacitor to soak up extra charge is limited whereas a battery has more room. The battery I use is relatively small .right now it's stylishly duct taped to the rear single seat style Hobbit rack or under the side cover of my magnum. Ya know Honda actually knew of the existence of capacitors when they out a battery on the express!!
I've always wondered if say you overcharged your battery ( maybe on a space based moped ride to say an adjacent Galaxy ) how the system would behave if battery resisted further electrons. I hope to focus on that existential problem on future posts.
