    I have (2) 4.5v LED lights strings I would like to wire into my battery system. Currently they each have a (3) AA battery pack for power. Has anyone used a stepdown power supply to a switch? Appreciate any options or links.

    if you had one more and wired them in series you would be good to go off of the battery at 3X4.5=13.5 (keeping it simple)

    otherwise, maybe something like this.
