I would have to fit a starter to do that  ;D
You can get a Cap Pack to do it, $99.00 though. You know I'm too broke to do that  ???

I am not a fan of stacking caps like that.  The chance of failure is much higher.   for instance, a single engine airplane has a chance of failing.  The number is low. A four engine plane, using the same engine, is 16 times more likely to have an engine failure.  Of course, one engine planes having a failure is much more dire than a 4 engine plane having one engine fail, but the analogy is a correct one.

One big cap has a MTBF.   12 little ones have a 12^2 (144 times) chance of failure.  In your case, a cap failing can take a fuse out, so you have the same capacity as a larger cap, with a higher chance of failure.

Since you are not using the highest quality and grade capacitors, your mileage may vary. 

Your idea is sound, and the series cap is a neat idea....But I would still get a higher rated cap. the charge of the cap is not based on the rating directly, so a 100 volt rated cap would not charge any higher (Charge state depends on voltage source).  However, it would be less stressed.....

It is a good proof of concept...but if I was relying on the caps to get me home, I would use a high voltage rating, as well as a higher quality cap....

Thanks MLK, I was hoping you would take a look ;)
It's just an experiment really, I need to get multiple batteries for various 360's   :(
 I've been reading about DIY circuit boards and various etch solutions. I don't have a lazer printer or access to one (plus, haven't got a circuit I need a board for so thought I would experiment with a Sharpie and stuff I already mentioned at beginning)
Thought I'd try a 'proof of concept' as I'm pretty much only using the CB to check other peoples carbs at present so a new battery may die before I get a chance to use it
I first found out about them when they were being used for regenerative braking on electric buses in Europe,  battery couldn't cope with a sudden 'XXX' amp input so 'ultra capacitors' were developed to take the charge then distribute it slowly into battery. Made any braking or even slowing down much more efficient as there was always some charge being applied. Turns out they could hold charge so battery banks became obsolete and the buses suddenly got about a ton or more lighter  ;D
They have been used long enough to reach the half million cycles and be swapped out for new ones (apparently, nothing wrong with the ones removed)
Of course, there are probably a few thousand under the floor but if Germany says it's OK it must be safe?  ???
The 'super~ultra' capacitors are only available in low voltages as far as I know? Most are 2.7v
Charge balancing circuits are available for larger size caps
The cost ramps up dramatically for larger sizes but they can be in the thousands of Farad range and are used instead of batteries

I was going to charge pack up again tonight, turned the power supply to zero, connected alligator clips and, it was showing 10.4volts after sitting at least 24 hrs
I turned voltage up to 14.1 and none went over 5.50v plus, the lower reading ones from yesterdays testing had come up so all are getting closer voltage which is probably a good thing  ;D

CPJ,

You may be on to something there....Maybe a "Hybrid", a smaller battery, then some caps to do absorb and supply transients. 

Our primitive electric systems really have poor regulation, in that surges and spikes can pass through the system. 

I like your thinking.....But if you like it, get higher voltage rated caps..

I have a pair of 36v but they are only 18,000uF, the mini's are 1F each so with the series /parallel connections I'm getting 1.3F.
Typing this made me think about checking the charge from last night, just checked, showing 12.84v so leakage is pretty low.
 I was thinking of using the lower capacitance /higher voltage in parallel to get 36,000uF then running into the mini cap bank
Also, had a thought about load balancing without specialised circuitry.
Use two 5.6v zener diodes going opposite directions between caps, if voltage spikes it will just pass to next cap in line, if voltage stays too high, it gets passed to electrical system of bike (basically same as running an energy transfer system, caps just act as a buffer)
I had also considered a hybrid using a 4A/hr battery which is much smaller than the 7A/hr so much easier to 'hide'   ;D

Not to mention that single phase power kinda sucks.

I'm just glad to read that your working on something.
Making that board at home is some cool shit, no doubt.

I'm beginning to wish I had taken pictures of the entire process.
 It really was much simpler than I thought it would be

Haven't had inclination to do much since being told to resign from Bankers Life and Casualty Company.
I think I was 'conned' into getting an insurance agent licence as manager implied selling insurance wasn't too difficult plus they supplied leads and training.
When I asked about 'cold calling' and 50,000miles or more driving he said there wasn't any which was a total lie, you were expected to knock on peoples doors inn the evenings and on weekends. One of the other agents had driven more than 20k in 3 months  :o
Basic cost was $318.00 for training and state licence, plus travel, food, etc.
It took from mid January until end of Feb to get things sorted out, Iwas 'assigned' March first and escorted off the premises 4th April
Probably cost around a grand total for the almost 5 weeks I was 'employed'. 'They' tell you it's your own business that you are building but you have to be in the office Monday and Friday to make phone calls plus Saturday 8:30~ 9 til 1:00.
I don't believe I was even given a fair chance, the company normally  'gives' 90 days  for you to get going and start ripping people off while pretending to be their best friends and looking out for their interests. I guess I'm just not dishonest enough to be an insurance salesman  >:(
Anyway,  I have been playing on lathe, made a few tach plugs and faced a couple or few billets for starter plugs, also playing with porting on 360 head plus a few other things and the usual 'make carbs work with K&N filters'.
No pictures t look at though, maybe in a few days
