Depends? How long you going to run your light and winch? I bought and installed this super bright 20 inch Back Oak Light bar, it's too bright for group rides, wish I would have bought two adjustable pod lights to light up the front side areas and a smaller light bar? Check out the club store for back up lights, plug and play, my kind of accessories!If I'm just looking to run a light bar and a winch is the additional battery capacity really required?
I wouldn't bother if this is the case.the machine would be running.
