The price has dropped on the
BCAP3400 supercapacitors! They were originally $80, but are down to $71 each. If purchased in a quantity of 10 or more, the cost is $67 each.
These caps have a higher voltage rating than any other supercap on the market at 2.85v. Most others are rated at 2.5-2.7v
They have a peak voltage tolerance of 3v, which means it is likely possible to get away with running only 5 in series instead of 6. At 3400 farads, they have the largest capacity for the money.
Anyone want to buy 5 with me to get the quantity discount?

Anyway a couple of things worry me about this supercap business. Having your capacitance cut down to 1/6 or 1/5 by using caps in series seems a huge waste. And I worry about the voltage spikes in the system.

My CBR maintains 12v at 1000 RPM idle. Once I swap the 55w headlight out with a 35w HID, I will do another test to see if the voltage is held higher.
The voltage doesn't spike any more than using a battery, peaking at the output voltage of the generator/alternator.
