RageNR,
What I would like to see now is research and suggestions of replacement caps, and maybe some photos w/experience reports from owners that have done the mod.
It sounds like you don't know research when you see it? Robocam posted a link for some capacitor calculations. I thoroughly read that paper and figured out the the useful equations applicable to our concern. I used the equation for derating capacitors for overvoltage. By the equation using 84v max instead of 80v results in 48% expected life 84v over 80v. This work is research about capacitors. And if they last 4800 hrs at 84v [predicted], which high voltage they may very briefly see, your FAT Ass will get bigger if you sit that much on a ebike seat in the next 2 years. And I will be LMSAO.
Again no one has checked what is the actual voltage the capacitors see. It is kind of like the sheep crying WOLF when no one has seen one.
You have seen some suggestions of replacement caps in a post from Spinningmagnets. Why not go for those he posted? You lazy FAH you can go to Dig-i-key and look them up? You say it is okay if they lay sideways. It may look worse than the washer job.
From my rational point of view chasing down a clean fit capacitor is not worth the time as:
1. I have just under 6 months left on my controllers warranty with Luna.
2. The controller cost $49. I make this much per hour.
3. The capacitor derating equation says I would get 4800 hrs at 84v when used at 84v all the time. The capacitor very briefly sees 84v and battery voltage immediately goes down under use and load.
4. gmans point is stupid and not to the point -- useless like yours. No QUANTITATIVE usefulness whatsoever. "If you overvolt you will shorten the life of the controller" Such a statement is absolutely worthless -- Knowing how much is useful: Remember 4800 hrs at 84v as opposed to 10,000 hrs at 80v.
You guys statements on caps is about as useful as saying your tires will last longer if you ride slow. We all know that kind of BS.
5. The controller rating is obviously
72v nominal and that means about 84v max when the batts are fully charged. No we are not
running outside of Cyclone's stated specs. Do you know what nominal means?
6. I can petal the bike if the controller fails.
When will we move on? And to your annal point ---
It will probably be when you no longer get the last post on this topic.
