After months of waiting on parts and trial/failure I have made my first super capacitor battery replacement. I used Maxwell 350F capacitors along with a ballance board. I cut bits off a copper grounding rod and soldered them in series between capacitor terminals so high current would not be limited by the ballance board tracings. I bought some battery terminals off of Amazon and found metal picture hanging strap was the perfect size to hold it steady and carry the current. Next I plan to add a small battery for parasitic load protected by a low voltage cut off and current limiter (let the capacitors handle the hard amp draw).
