I am very happy with the setup and all the advice Ive received here. Just bought my switch and some more wire to get things routed more neatly, but it's pretty much done!
Very nice setup. The Vector battery pack looks great and would have cost less that what I spent in a battery, case, fuse, and two chargers but I somehow managed to miss that one. It is easy to miss good information in this thread because of its size. Anyway, I already have all this soldered together so I am past the point of no return.
