Thank you very much I will try that.

What do you think, are we making some progress or should we stick to your design

Great videos

I see your pulses are decreasing when your battery got charged

Self regulating because the voltage on the battery get nearer to the cap's voltage, and the input pulses decrease because the cap discharges less in the battery, then its voltage is closer to the input voltage. Logical IMHO.

Bedini's show the same effect

I passed an order for the 10A one, the cheapest, still 465 USD, not including VTA ... Renaissance Charge - Intelligent Solutions to Premature Battery Failure

I was quite deceived by the Rennaissance RC-1AU-240, because it is VERY noisy. But it works for battery rejuvenating.
I use it on my electric bicycle, 24V battery, and it charges very slowly, like 1 A/hour ...
I was expecting more, but nevermind it's better than nothing.
It is also very heavy because of the 240V transformer, and costly for what it is, 700 USD with shipping and French VTA !

And now their prices have increased again !!! The Renaissance RC-1AU Universal Radiant Charger for Small Rechargeable Batteries (far to be humanitarians, they are "good" businessmen at least)

If you don't mind I prefer to order one experimental from you ! To test the results before

@scratchrobot
I would recommend we first grasp this circuit and the best "sandbox" I found so far is what I've built and shared?

It has it all: where we can save and where it takes "power" to make it work.

Therefrom we could (and should though) go try build a device that can sustain 20A on input (400W)?

I exploer MOSFETs right now

so a resistor value of 10k and 22K works pretty well.

Bit's

@Scratchrobot, correction on the resistor values R8 = 10K, R7 = 2.5K.

@Bit's
Thanks.

@jules Tresor
The circuit I use is as simple as it gets and if you want to replicate it I will help you, it's not that difficult to do. I suggest you replicate StevanC's version because I agree, it has it all.
Even better, try to replicate this

Thanks, I hate electronics, I have no patience for soldering

I am good to open my mouth loudly, to make contact in a township, I am good to organize manufacturing, project development, fund raising, and a few things useful like making website, selling online, learning languages ...

but NOT GOOD at making electronic circuits
I wish I was because it's the most powerful thing in this world, electronics are everywhere and do lots of things for sure

We are made different to be complementary, to share the work, 1 team of specialists is better than 1 multi-skilled guy.

Sorry I leave this part to specialists, but I can send money to whom can make me one. I'll be pleased to help that way !

Edit: my present hobby is transmutation, bacteria making gold ... quantities are very small now, but I hope one day I'll live on that.
Since I saw Bedini DVD 18, I am very interested to try his method, but need a 2500F oven, and that's expensive just for testing, I am not sure I can reproduce his process !

[Xenomorph]

Just breadboard it then, if you dislike soldering.
I breadboard most stuff, because i always swap components.
These type of circuits are really simple to put together.

Jules, 465 USD is comparable to other quality charge controllers on the market that claim similar, but not quite what the Tesla Power Amplifier can do. Don't compare the Tesla Power Amplifier with the cheap $100 units that can't do what it can do. The cheap ones can't restore your batteries and work in low light as well.

Jules, the RC-1AU-240 I have is no more noisier than I would consider normal. About the same amount of noise as a florescent light transformer when on the highest power setting (24V). When I use it to charge the kid's toy batteries "AAA's, "AA's" etc. on power level 1 or 2 I don't even notice it is on. Perhaps yours has a loose cover screw or something. Make sure it's sitting on a flat, solid surface as well.

A 24V battery on my RC-1AU takes a few hours, longer if the battery is totally dead. What type of battery are you using? If it is a gel-cell it may have dried out and even the RC-1AU can't bring back dried out batteries!

I'm not sure where you have seen USD700, because the web-site is showing USD483 which includes international shipping.

Thanks Bit's

First you must set up a voltage divider. Let's say the desired voltage of the battery is 12.5 Volts. You will need the voltage divider to present you with about 2.5 volts so a resistor value of 10k and 22K works pretty well. Once this is set up correctly, @12.5 volts the chip will see 2.5 volts on the pin you have selected for the ADC input. On the attached drawing, pin 0 is the pin sensing the voltage divider, so your command in the chip will be "ReadADC 0, Volts" (or whatever variable you choose). If your were to look at the value of "Volts" in this case, you would see that the value is 127. In the digital world, an ADC pin see's values from 0 to 255. This is why you set your voltage divider at half scale so you'll be able to read the voltage swing from about 10.5 to 15.5.

Hope this helps.

Hey Bit's,

Thanks for the tip and the pic, I'll try this on my PICAXE too.

Sorry I haven't been posting much, but I'm still working on variations of the TS every now and then when I get an idea.

Would your circuit work for sensing capacitor voltages instead of battery voltages? Any mods needed?

John K.

Hey John, good to see your back. No mods needed, just make sure your divider is "tuned" to your voltage range, 2.5 being the middle. You'll notice that I put a 4.7 zener to prevent the pin voltage exceeding 5 volts. The chip does not like any higher.

Thanks

Hi John,

Wanted to know if you could tell us your best result with the Tesla switch?
Solid State or Relay-Based, What frequency?

Thanks

[Jules Tresor]

@John,
Sorry it was 600 USD, not 700: 120 USd for French VTA in supplement. They stop big packages like that and charge you 19.6% VTA + Custom fees.

I bought a car battery charger for 60 USD at the supermarket, Bedini's at 600 USD, it's COP 10 for him.
I ordered a 24 V desulfator from Malaysia for 50 USD, including shipping, waiting for it. But at least it looks small and light. Don't know yet if it will work but they seem less "hungry" than Bedini.

Really my Bedini is VERY noisy. Imagine an old fridge compressor going wrong and making noise, and you have my Bedini charger
And the vibrations propagate very far. Have to say that I am living in a flat at present time.
I can't run the Bedini at night because the neighbors will complain, it's that simple. May be I got a defective one and others are not so noisy ...

My bicycle battery is new brand, 24V gel 7 Ah. I bought this bicycle with lead-acid batteries just to try the Bedini charger. So far so good, after may be 60 charging cycles (half with the Bedini charger) I notice no decrease in autonomy. Of course I have no double blind study, so I can't compare to the same bike used without a Bedini charger.

I am really deceived by this charger, especially at such a high price. But of course I might come back on my investment in 10 years after saving a few batteries from going to dump

But I found invaluable info in the DVDs series, and I learn a lot from Bedini disclosures on his motors and circuits. I love Mr Bedini, and I know that everyone is limited, so I forgive him for not disclosing his most "powerful" designs.
Actually it's not my responsibility if he conceals data that could save lifes, it's HIS I am just sad for those who could be helped with such knowledge.

This being said, please gentlemen, back to experiment, we have free electricity to produce !

Hi Elias,

I have made probably over twenty different versions of the TS. Each one teaches me something new. The best variation I've had so far is the vanilla Tesla Switch with a SS SSG as a load and then dumping the caps into one of the banks.

I've still got a lot of research to go though. I have a few ideas I haven't tested out out yet so I'll keep playing with something until I have a setup I like.

Jules,

Man, that French VTA really sucks. But I suppose you pay that on any international order, even your desulfator from Malaysia. In Australia I get charged 10% customs duty and a further 10% GST on imports. So it's nearly the same.

I just charged up a 24V 7Ah battery with my RC-1AU and it only took 4.5 hours. At 22 cents/kWh it cost me about 3 cents to charge up my battery.

If you can ride your bike all day for that sort of money then I'm sure you'd agree that the RC-1AU is worth the money. I'm sorry you seem deceived by your RC-1AU. I have found it to be a great charger and it's already paid for itself. If the noise bothers you, put in a place where it doesn't.

Don't let the price fool you. There are a lot of battery chargers on the market that are designed to kill batteries. The Bedini technology will do a better job of charging and your batteries will get better over time instead of worse.

For a car battery charger and rejuvenator you are better off with the Spanker RC-2A12. It only draws about 60W from the wall (@240V) and puts an amazing charge into a car battery. At USD280 including shipping you only have to save 2 or 3 batteries and it has paid for itself.

I've also learned a lot from the EFTV DVD series, as well as from what I've read and my time on the bench. I'm still continuing to learn and experiment. John Bedini is yards ahead of anyone but we have enough information to be able to try and figure out what he's doing. It's not that hard once you can grasp the concepts of what John has been talking about all along.
