how to fit cap board

[ManuelW]

@ Steven:
They will probably work great but I wouldn't use them. With their size of 18x40mm they are just too huge in my eyes. But for pure function they'll work great.

Last week-end I upgraded a pair of T180's with three 35V 1000µF each, I think thats enough and I can recommend it. I also soldered it directly parallel to the caps on the circuit board.

Best regards,
Manuel

I think thats why Steve started stocking some DIY caps for members to improve their own speedo's. http://forums.offshoreelectrics.com/...ad.php?t=21623

I'd like to add a capacitator bank to my Hydra 240. Will either of the ones that Steve sells work on the Hydra. the stock capacitators are 35v, 390uF ZLH. thanks for the help!

You can add this OSE cap bank and it should work just fine. http://www.offshoreelectrics.com/pro...035-lv&cat=136

I recently added that cap board to a lv hydra ice 240 running 8s1p in my Sniper and am very pleased. The boat has more immediate power and the ripple current, which Castle techs tell you to monitor, was cut in half (ripple volts went from being 5-6% of average volts down to around 2.7-2.9% ...very pleased) ....there is also a slight reduction in tempurature of the stock 2 capacitors on my unit.

I have made my own capacitor banks, and still have some for sale if anyone wants them.
These caps aren't Rubycons, but Japanese NIC low ESR caps (35V 1000uF) just as good as the Rubycons.
The cap banks also have schottky diodes for tampering spikes and tiny ceramic caps, for RF noise filtering.

Sounds good, thank you!

My issue is heat on the capacitators, hope this etti cap bank helps.. glad it's working for you!

I just picked up some ancient (but new and unused) Nichicon PL series capacitors today at the local electronics junkyard.

Everything I can find online about these says they are low ESR. I managed to download a datasheet for them.

The caps I got are 63v 1000uF and the numbers off the datasheet are:
Impedance - at 20 degrees C - 0.027 ohms max, at -10 degrees C - 0.054 ohms max
Allowable ripple at 105 degrees C from 10kHz~200kHz: 2370mA RMS, at 105 degrees C at 120kHz: 2050mA RMS

Are these caps useable on my 1st gen Aquacraft 60A ESC (with the smaller Rubycon ZL 27v 68uF cap)?

Old electrolytic caps are always a suspect. They dry out slowly. Even though they haven't been used, they may have lost part of their electrolyt. This may or may not be true in your case.

If not too old, they can be reconditioned (see pic). If the electrolyte is dried-out ... no such luck.

I just got a dozen Rubycon ZL 50v 820uF capacitors and installed a pair on each of my Aquacraft ESCs (A Motley Crew, an original UL-1 ESC w/ small cap and an original SV27 ESC) all of which came originally with Rubycon ZL caps from the factory.

I was going to go ahead and install a pair of caps on my Turnigy 80A ESC's, but they came with Rubycon ZLH caps. Can I use ZL caps along with the original ZLH caps on the Turnigy ESCs, or do I need to get some ZLH caps to use with them?

Photos of the ZL caps in the MC, UL-1 and SV27 (still needs some liquid tape) below:

Why buy a cap board? Get 2, yes you dont need a freak'n herd, of the right size caps, two 1000mfd 50vdc caps will work and are plenty, put them between the batt leads. Thats 125% more capacitance then stock from the factory. But get only the best caps. Not some "sort of" close version. Buy EXTRA LOW ESR caps. Regular or normal caps will not work!

John

John, you busted me ! Actually when the "extra caps are good" thing started some time ago, I loaded up on the Etti boards. I had 'em, so here they are on two T-180's. Make SURE the bottom of the board is insulated from contact with the speedy. On the one that sits right on top of the T-180 I bonded a piece of G-10 and then some electrical tape on the bottom of the board. ( At Joe's, not long ago, an Etti board on a friends boat exploded, one cap at a time, when the bottom of the board contacted the speedy upon plug-in. Sounded like a pack of firecrackers going off !) Lately I've been using a pair of the 25V caps pictured on my spec speedys. Not sure if they adequately spec. John ?

I'm thinking of getting some of these for higher voltage.
http://www.rubycon.co.jp/en/catalog/...inum/e_ZLH.pdf
the 63v 2200 version.
How will those work?

Those would be nice additions to your inventory Steve. Offers the 6S and higher voltage guys a broader range. Its tough to find 100v and higher caps in the larger capacitence values. Due to body size most of the smaller diameter/ higher voltage caps only can be found at 220 mfd. So then you one would need at least 4 or 5 minimum. Stock them. The will sell.

I wouldnt use 25v caps on anything above 5S. Just for caution sake. For my own speedos? I wouldnt use 25v caps on anything above a 4S rating. The larger value give lots of room and most importantly it costs you little to nothing to use larger caps, yet gains you increased voltage potential issues. Thats pretty wierd about the caps going off like that. Never seen that myself. Hopefully the gods of electricity were happy with that minor sacrifice.
