There is simply no way anyone needs to build their own pack, excepting maybe soldering on polarity proof connector. There are too many excellent pack available at prices that you can not even beat by building your self.

This thread is too ignorant of reality. And it also ignores the ease of simply subbing in NiMH AA packs/carriers.

What's next? Bike horns and bells made by hand? Maybe an analog speedometer?
