    What do you want to know in particular? Its an internal battery replacing the old standard, which owners need if they want to use the new D-Fly unit. You can fit it inside the seat post either with the expensive Shimano and aftermarket clamps, or as I did by wrapping it in just enough electrical tape to securely wedge it in the seat tube. Connects to Junction B exactly the same as the old version or via the D-Fly unit if you use one.
    I ride a bike. Doesn't make me green or a tree hugger. I drive a car too.
