HI, sky i wish you success . To prove that this system works is easy,
just get the voltage booster started with a battery, then the output
charging a 10 farad capacitor and lighting up the led. Then through a
double pole double throw switch just configure to start and run .

Hi seychelles, thanks for the reply and the video link, I will study that video soon.

The system does work seychelles, the battery is recharged with about 90% of the original input energy and that is not including the work done in the led bulb, which is the same watts that is charging the battery.

So around 180% minus battery charging losses or 1.8 COP, using these particular parts of course.

Though the true energy in the system is 239%, though not all of that is accessible as work or power.

A more efficient boost converter and more efficient battery or capacitor as you are pointing out would improve these numbers.

Hi gyulasun, thanks for the reply.
It is only using just 1 tractor battery at the moment, though I'm not sure that is the best way, maybe a separate charge battery would be better.

I'm still testing, Currently in the process of charging with digital charger to a specific voltage, then disharge with system, then recharge to know what was used in the battery.

Edit: hmm, i get 98.4% efficiency, and that is when using my lithium ion 3 cell in series pack.
I will make new test and use my 12 volt power supply to run the boost converter and use the lithium ion as charge battery and see if anything changes.

Yes, i jumped the gun, the results were not anything out of the normal, with the parts and arrangement shown.
Though, the other thread, with the 12 strand coil charger, at least does show true extra energy into the charge battery.
Will focus more on that set up, thanks gyulasun.

Hi all, I'm trying a new circuit, one that includes capturing the flyback, while splitting that with a 12 volt led bulb load.
I have the 3 cell lithium ion battery packs made to be quickly rewired to series or parallel, for swapping positions.
Another benefit, is in using the higher charging efficiency, lithium ion cells.

Hi all, the results so far are looking interesting.
The average watts used at any given moment over the testing period so far, is around 10 watts, since it is varying after each test run, as the input side progressively lowers in voltage.
The current flowing through the 12 volt 7 watt led bulb is around 900 milliamps.
I tested a single lithium ion cell to determine the amp hour capacity under a given load, I used 300 milliamps current to discharge the cell using my digital charger.
The cell was able to give 600 milliamp hours drained down to 3.6 volts, which is the voltage I have been draining the input series side to or 10.8 volts for the series battery pack.
That is around 2.25 watt hours available per cell or 6.75 watt hours per battery pack, when drained to 3.6 volts per cell.
The experiment has now run for 3 hours 16 minutes or 32 watt hours equivalent and the experiment is still not finished.

Though I am questioning if the input side, series battery is actually giving 6.75 watt hours capacity, since the current flowing is 3 times or 900 milliamps, compared to the 300 milliamps current drain used to determine cell capacity.
Since each cell in a series battery uses the same current, the actual capacity using this load, may be around half.

Well then, so far, if we assume each battery is giving us 6.75 watt hours capacity, which i doubt, i think it is less than that, then we have a total capacity of 13.5 watt hours, to run this setup.
Well, so far, the setup has used around 32 watt hours and the experiment is not finished yet, still has at least 2 or more good run times left i would guess and each run time down to 10.8 volts on the input side, has been around 50 minutes duration.
Your questions or comments are welcome.
Will continue with the experiment now.

Hi all, I was recharging the battery packs and realized something.
When I drained 1 amp hour, from the battery designated to be the charge battery for the start of testing, I forgot that each cell in the 3 cell parallel pack, was drained of 1 amp hour or around 12 watt hours total.

The efficiency numbers I posted are too high, It's more like 1.85 COP total system efficiency and 1.4 COP led load efficiency.
I will make another test, this time, only discharging the intial charge receiving parallel battery of 4.2 watt hours or 350 milliamp hours shown on the digital meter.
Which, at an average of 4 volts per cell, that is 4.2 watt hours total from the parallel lithium pack.
That's all for now.
