I never got around to permanetly installing the caps into my car. The ones I was using are not super caps. They are just computer grade caps. So they don't have all of the storage of super caps. I wasn't using it to gain range, I was trying to use it as a funtion of battery longevity. I took it out of my car and a few people have played with the caps. But I have them back now, but my battery pack is shot. I am buying a new lead acid pack in December so I can start driving my EV again full time. I may revisit the caps again once I have a base line again.

Are there specs or information you can send me regarding your super cap battery wiring etc? I have thought about doing that for capturing regen breaking etc. Thought it made way more sense. How is this working for you? Saving a lot of battery life?

supercaps are wired in parallelo with the batteries, electricity always prefers the line of least resistance so in a battery+supercap arrangement the supercap is drained first because of its miniscule internal resistance compared to that of a battery. Once the supercap is "drained then; and only then will the battery supply power to drive the vehicle. When "all" is drained, and the charging has to begin the supercap takes "all" the supplied charge until it is full then, and only then will power feed into the batteries. battery charger used on this system needs to have a "current" charge control or the supercaps would try and charge at absolute maximum and probably melt the charger.
