I'M SICK OF THE SHIT!!!!

Us too. Perhaps find a forum that is more willing to cater to your ego? You will be happier and we will be happier. Everyone wins.

Lived in Oklahoma, USA for 13 yrs and remember the increase in earth quakes. The last several years it is not reported in the news anymore. They are linked to oil extraction. Not heating but shifting pressures in the North American Plate. Fluid is extracted at lower levels across the State then oil...

What amazes me are the people who get busted on fb. I watch a lot of The First 48 on the television, the first place the detectives go look for acquaintances is fb. Then you see the criminal has uploaded pictures of lots of cash, and drugs and of course guns. Get full facial shots of the entire gan...

Dont know What’s the problem

The problem is that you are trying to build a perpetual motion machine and those don't work.

Does anyone know how exactly the controller determines mosfet temp?

It's almost certainly a thermistor. They are cheap, small and simple. There are ways to use specialized FETs to measure internal die temperature, but then you are locked into a specific (and expensive) FET.

In the US in the 1960's, everyone knew that "our rockets always blow up" and we were wasting billions on a failed, futile attempt to put man in space. Until it worked. ahem... you mean until the churminz showed you how. Oh, even well after that. Von Braun got to the US in 1945; for the next 15 year...

Designed for powerwall applications......
8-cells: Each cell is 220ah and about 20lbs.

Sounds like the BYD packs. Where are you located?

It's all about getting government grants and billions in investor money to pay themselves to try and do something they probably secretly knew was never going to work from the beginning. That was true of solar-PV, the space program, the US road system, airplanes and the Internet, too. In the US in t...

the stories are a couple years old. anyone have experience with this technology? From the page: "Over three times more efficient than Silicon panels." So that would be 60% efficiency. The highest conversion measured, ever, was 46% for a concentrator quad-junction cell by Fraunhofer. So I vote "vapo...

]Suggestion to moderators. Internet forum's are like children playing in a sand box. Might be best to just let the children play, argue, learn, and be children. That's fine; I am all for that. But you don't let children spraypaint cuss words on the front of your house, or break the windows, with th...

They said that an advantage of solid state batteries is that they don’t require a separator because the solid electrolyte serves thank function. Separator makes sure the anode and cathode don't touch. If the electrolyte is solid it serves the same function. Layer of cathode, layer of electrolyte, l...

This is based on some pretty old data. Leafs now have ranges of 150-225 miles, and Prius Primes have ranges of about 25 miles.

Now, every one knows the warmer Earth gets the more active the plates will be. More earth quakes and increased volcanic activity.

Nope. No known connection there.

Broadcast media is RAW POWER, and humans are simply incapable of not abusing it and using it to exert their personal political will. The situation we live in now is that "broadcast media-power" is like "The Lord of The Rings power, and once it is finally destroyed by a coming IP-Streaming media onl...

I'm in the middle of making some upgrades to my ebike controller and I'm having a hard time finding a low ESR capacitor that will fit my needs and was wondering if anyone had any suggestions. Let's back up. Why do you need a low ESR cap? EMI filtering? There are better ways of doing that. LF ripple...

Here is some good news for you, San Antonio, TX city counsel decided to keep our coal power plants into the foreseeable future. They even bring it in from across the country and don't use any from Texas and it cost more than the natural gas we have here. Well, at least your electric rates will go up.

The video clip is probably faked then.

They did find a few car parts and pieces of clothing - although not the main wreck itself.

Damn... Any solution from eBay without going to digikey and ordering a single relay that will come without a pcb? If they are resistive loads, just use MOSFETs. They are cheap and easy to use. You can get a 120V, 60A MOSFET for about $1.50. You can drive them with TTL signals (0-5V) If you really w...

That go up to 30A but they are all rated 250V while if you look at the relay itself it says 250VAC/30VDC
Do you think I will fry it at 100V from a battery?

Yes. It will arc if you try to switch it under load.

Sure I could just have asked what their voltage is, same difference

7 modules so 14 cells (50V nom)

A gasoline, diesel, or steam engine converts a fuel directly into a spinning shaft. The "fuel" is not consumed elsewhere. True for gasoline or diesel engines. A steam engine is an external-combustion engine where the fuel is consumed in a boiler, and then steam transfers the energy to the motor. Th...

can someone tweak my given circuit or give me a better one. the smaller and simpler the better. Your problem is going to be that at .5 volts (what you get out of a single cell) you are going to be hard pressed to do any sort of a timer. Consider something like this: https://www.digikey.com/product-...

That's a great idea, but your are LOSING money, and sending out a lot of cells to trash or no useful app for those tired cells. Not contributing to environment. Rich people buy $5K ebike and many batteries but regular people can go at reuse concept with great amazing cost saving, clapping hands and...

>> Assuming no gearing, lower kV is still useful when more torque at lowest possible rpm is required and top speed no issue at all, right? Would be greatly appreciated if this could be answered, I realize a bit prosaic for such high-level discussion Yes, it is useful. With caveats. To explain why l...

I have a 48v 1000w wheel and I believe the RPMs are 450. My battery is 52v
What would be a good guess on on the Kv?

1Kv = 1 RPM at 1 volt.

450 RPM at 52V= 8.6Kv, so try that.
