Front Battery Hub

Bill on the TF forums was nice enough to offer first-come, first-served, a free used TF front battery hub. I quickly asked him for it and it finally arrived a few days ago. This guy is hefty! I'm not sure what condition it is in, but I suspect that it isn't working very well. I plan on taking it apart to see what's going on inside and to either replace the batteries (there are 30 8AH NiMH D sized cells) or gut it and just use it as a front wheel.

We will see what happens when I open it up!
