12 500f super farad capacitors

A 1 Farad 12v capacitor like you would use in an car audio installation was simply too expensive and had far too little power storage. One reason I had been considering capacitors was not for power storage but for the side effect of cleaning up the overall noise introduced by the power system in the car.

Super capacitors come in a few common shapes and sizes but by far the cheapest for the power are the common 2.7v 500 farad units. To hit the target voltage I needed (12-14v) I needed a few wired in series to increase the overall voltage. Fortunately this is a common solution as its a typical voltage used in solar installations.

A good explanation and test is here: Capacitors have come on a long way though and the new generation of “Super” or “Ultra” Capacitors are starting to become a viable alternative to a battery in a car. Because of this, I thought it only sensible to buy some parts and see what it was all about

Also, a point of note is that even though the planned bank has a capacity of 16.2v it will only operate at the voltage its charged too, so if the car charges at 13.5v then the bank will be charged to 13.5v. Its also important to balance the load across a serialized bank of capacitors to prevent damage.
