wiring cap bank

[urbs00007]

I am presently wiring a cap bank with (5) 1000 mf 50 volt capacitors. do i wire all the pos. together and all the neg. together?

Yes.

[oscarel]

Yes if you want 5000mah

No. In your SAW application you want each cap to cross the positive and negative power leads. Your caps are too big to wire all the positive and negative leads together before they connect to the power leads. Putting them all together on a pigtail will reduce their effectiveness significantly if used on your powerful high rpm setup. Here is how I did it, the result was a reduction of ripple on 6S from 3.3 volts to just one volt at 260 amps. Highly effective in increasing performance and reducing ESC damage.

On my saw set up I use a Hifei hv cap banks and I don't think is crossed but will check it out...anyway good info here.Thanks Gill

what ripple voltage were you getting?

Tough to tell from that little photo Chris, it's actually an Aeromarine Shadow Sport Hydro.

Sorry, getting off subject kinda but fluid what setup du u have on thos boat
Have the same one with a 4092/1390 leo
And sordfish220pro + on 6s wondering if should add cap bank

Could u show a schematic of how u wired ur cap bank and how u soldered them together thanks mike

I was interested in an underside view myself. I ordered some caps the other day so I'll be needing info on how they are wired up myself.....

The hydro is a SAW setup using 6S1P and 8S1P - so it needs all the help it can get. I'll try to take a pic tonight of the underside. All the caps are glued together with E6000, then soldered to the power wires.

Ya if u cross caps pooffffff my gut fleeling is parallel + to red - to black up the line but not sure
Building own cap bank $save. caps 1.00 each ...

thanks Jay, that will help. are you running 5 in series? or are they in parallel?

My batteries are on the Tunnel where where do you fit a single 6s or 8s?
