Cusdn has told me the same
Id like to buy some of his cis solar cells, but I think his prices with shipping are still on the high side.
Yeah, caps for audio seem to go down in price and go up in capacity. For the super caps that can be used to start a car, they seem to go up in price and are hard to find or find enough to make a 12 or 14 volt pack.
If I did do this, Id get the balancer circuit and use a solar panels to make up for the electrical losses in the newer cars. Mines is like 60ma an hour.
