Yeah I agree on the money better spent on batteries thought. But I just cant afford or rationalize maybe the high expenditure on a first time project. Im still largely a fossil fuel guy. Hate to have a mega$$ battery pack gathering dust because I couldn't appreciate being moved by electrons. Im going with 15ah SLAs. They are compact and weigh 29lbs(3), and importantly cheap. I have read about all I could find on them and know how to baby them. Found a 4 stage pulse charger that aids in de-sulphation. Am still curious about the super caps as a protection for over amping the batts. From what I read current can be drawn through the caps with out discharging them as long as the battery supplies the amperage, once the batts. amps are exceeded the cap momentarily rises to the demand protecting the batts. I guess once discharged they would only recharge to what amperage the battery had left to supply, which is all you would have anyway. MY theory is anyway that a properly sized group of caps would have a threshold that was entered only when the poor SLAs had reached max amps and the caps would only supply the need draw, not totally discharge in a flash of amperage. Granted a prolonged overload would totally empty the caps, but possibly the SLAs would have escaped any harm. The upfront costs for the caps are high, but with care will cycle almost forever. In practice I will probably just ride the SLAs, but I find the concept interesting.
