Yes, it will be available in a smaller form factor. The core of the device will be a single modular design that will be inserted in the shell shown to give it the Group 35 size. Thanks for the kind words!
Nope! It could be the exact same internals. We'd just need to repackage it. The voltage on the capacitors is determined by the systems charging them. As long as its below the absolute rating for the caps, it will work. I believe most motorcycles actually operate at the same voltages as cars, though I could be mistaken.
