I have a 1975 Honda CB500T and I want to put small battery (4 cells EVO2),and I'm building a custom. I was wondering if it will work with kick start only and Head and Tail lights.. I want to make sure if that will work and go very well?? The Battery is Ballistic Performance 4 cells EVO2.. I have heard some poeple said LifePo will work and i have seen and about 2 lbs but the EVO 2 only has under 1 lbs? whats big difference? Need to know as soon as possible.
