We can't post links to live auctions that are not ours. There are a lot of dealers. You just need to find one that also solders the resistors on for you. They are out there.
That's the caveat for running lights on a battery. You restrict yourself to how many LEDs your battery can drive versus for how long versus how many batteries you need to cram into a model. That's why I always go for a plug in power supply. Like I mentioned, I've turned to using cheap cell phone chargers. They come in many ranges from 5v, 9v and 12v. I stick to 9v chargers, why? I have no clue. I have nearly 50 LEDs in my 3 foot Galactica all running on one 9v cell phone charger as a power supply. I shudder to think how many batteries it would take to run that for just 24 hours and maintain the brightness without dimming. Plus replacing batteries all the time can be expensive. I let it run for almost 6 months straight in my living room. I wonder how many batteries I would have gone thru!
Edit- But you would have to cut into the model to change batteries. Timmy, I'm not trying to sway you one way or the other. I just find in my own experience that a wall plug is much easier to set up.
