just finished my first bedini energizer and already problems :(

[prometei]

hey everybody

I've gathered all the parts together and assembled them into a "compact" unit.

How do you guys measure the voltages, when?  I've seen many videos on youtube where the voltage is measured directly from the batteries while they are hooked up to the charger while it is running.  I did tests while the motor was running, right away after the motor was stopped and the batteries disconnected from the circuit and 10 minutes later with the batteries still disconnected. The measurements differ. Which readings should one use for statistical purposes?

also, how does one use the little (25mA min) light bulb in order to find the sweet spot ? I don't have a light bulb in the circuit so I just adjust the variable resistor until I get

1. max RPM with min current or
2. loudest clicking with least amount of current

I'm not really sure if these are the correct ways for adjusting the circuit

@ Bourne:

I went back and watched the trailers for the Energy from the vacuum series on the link you posted.  This is great stuff.  Do you know anywhere on the web I might be able to view the entire videos without purchase?  I know, they need the money for research, but I can't afford them right now but would love to see them.  Thanks.

Hi prometei  Looks good!

You will find the battery voltage drops a little after charging, that's normal. Think of it like a gas pressure in a balloon, the battery being the balloon and your charger being the pump. When you disconnect your 'pump' some of the 'gas' leaks out and continues to leak out over time.
Mr J Bedini always said it is better to put a load on the charged batteries straight away. It is not like a 'normal' battery charger as you will learn!
If your worried about what voltage to note down use them all. I would suggest noting a 'running' voltage, a 'stopped' voltage and an 'after 5 minute rest' voltage you might see some improvements (battery conditioning) if you make a large spread-sheet. Don't bother trying to measure current flow out of your charger, it doesn't use current to charge your batteries. But 'do' measure current out of your charged batteries when under load testing

Its almost an instinct you have to develop when tuning your machine. This is because every machine is different. The way I tuned mine was to test every 10 ohms of base resistance from 1000ohms down to 150ohms    I charged the battery for half an hour then timed the discharge down to a set voltage value i.e. 12.40volts. Yes, it took ages and ages (2 weeks I think!). I have a massive spread-sheet showing all the times and voltage values etc. but it would be meaningless to anyone with a different set-up.
The general idea is to get the lowest current draw from your run battery with the best/highest charge appearing in your charge battery.
My final conclusion for my machine was 540ohms base resistance (yours WILL be different). Then when you have found your 'sweet spot' swap your potentiometer for fixed value resistors.

Like I said, its almost an instinct you have to develop based on your set-up. There is no easy way, just hard work.

Point one is basically the idea, fastest RPM with lowest current draw.
I don't understand your point 2 "loudest clicking with least amount of current" ?? What is clicking?

One other thing; try and use large diameter 'fixed' or crimped leads for your batteries.

peace!

@ Bourne:

Thanks.  I found them here and just watched part 1.  Amazing and very well done documentary.  This link requires the free VEOH player...very good resolution.

Yes, the voltage of the primary battery drops while the voltage of the charging battery actually increases, that happens a couple of minutes after I disconnect the batteries from the circuit.

I don't understand your point 2 "loudest clicking with least amount of current" ?? What is clicking?

Well I've meant this buzzing, ringing sound,  kinda like very very vast clicking, it starts slow but as the rotor speed increases you can't tell the clicks apart anymore. If I increase the resistance of the potentiometer the sound starts to faint.


I'm doing charge discharge testing now. I've got two 12 volt 3.4 Ah C-20 batteries and I'm using 160 mA fans to discharge them, would it be ok to use something like a 300-400 mA bulb?, that's higher then the c20 rating of these batteries.

ciao!
