This may have been posted before, but here goes. To light the passenger cars without voltage regulators, math, or even thinking, I used peel and stick dimmable 12v LED strip lighting and a 9.6 volt NiMh battery. Then linked the cars together electrically using RC servo motor extension cables. 5 cars will run 3 to 4 hours on a 600mah battery without noticeable dimming.
