They use the same sound board as other locomotives with a battery, so one presumes that with the correct cable you could add a battery. Fitting it into the VL-BB locomotive would be a challenge. FWIW, the board used supports a battery, here's the one in the VL-BB tender and locomotive, note that both still have the battery provision.
My solution will be to use this when I get around to putting batteries in, I know the guy that makes them.
And when you do that, please post a how-to and I will follow suit as my VL BB does drop sound in one place sometimes. That and It'd be a good example of how to go about it as I have a couple Legacy locomotives that don't have battery provisions that I want to add to. Maybe a roll your own YLB so it can be split and mounted to fit in odd spaces.
