Oscillator Powering 6 Modified Led bulbs

[Naija]

Hi all, Hi magnetman, I agree with the advice of gyulasun.

I have been making some experiments with my dual oscillator circuit that is powering the 8 led bulbs.
It has been working very well for me, when i need a lot of light up here.
So i decided to try the setup using the 3 battery, split positive method to power it.
The input watts to the circuit is normally around 8 watts with the 11.7 volt input from computer power supply.
With this 3 battery setup, that input voltage to the setup does diminish a bit over time, to about 10.5 volts when the charging battery is at 14 volts, yet still allows the led bulbs to output very good light.
Some interesting results so far, using the 12 volt tractor batteries.
I have started the test with Battery A and B in series as the primary input and battery C as the charge battery.
Rest Voltage, batteries have not been used for at least a couple weeks:                     
Battery A = 12.50 volts
Battery B = 12.52 volts
Battery C = 12.495 volts
Overnight Rest Voltage after 3 hour run time:
Battery A = 12.51 volts
Battery B = 12.515 volts
Battery C = 12.725 volts

Seems rather interesting so far, i will be continuing these tests by alternating the batteries to see where this goes.

Hello Skywatcher, can you please explain more about the 3 battery - split positive method? How does it work? Diagrams will be appreciated. Is there a link to an article where I can study that? Thanks in anticipation for your reply

Hi all, Hi naija, matthew jones and turion have done a lot of work using the split positive, 3 battery setups.
It is basically whatever you wish to power, placed between the positives of the 24 volt series battery and the single 12 volt battery, so the positive is the positive of the batteries in series for 24 volts and the negative is the positive of the 12 volt charging battery.
This gives you 12 volts for your load, so the batteries are essentially in parallel.
Then your load is between the positives and the negatives are connected directly to each other.
Still alternating the batteries and running the circuit for 3 hours and then letting it rest.
It is interesting to note, that the 3 batteries started out at a combined total voltage of 37.515 volts.
With 9 hours of total runtime so far and one complete cycle or all 3 batteries have swapped positions, with probably an average wattage of 7 watts, since the split positive voltage reduces as battery 3 charges.
The total combined voltage of the 3 batteries is at 37.64 volts.

Thanks, very educational. Am glued on, looking forward to your results!

Hi all, Hi Naija, your welcome, i hope i have good results as well.
So far, it is getting interesting.
I have placed all 3 batteries in parallel, to equalize them.
The total voltage is resting at 37.65 volts.
This after 12 hours runtime so far, at around 7-7.5 watts average being used between the positives,
or around 90 watt/hours.
Now remember, these 3 batteries started out at 37.515 volts total and had not been used for a few weeks.
And overall, they have been climbing slowly in voltage.
We shall continue the experiment and see where it goes.

Hi all, so after letting all 3 batteries equalize half of yesterday and into this morning, connected in parallel, these are the results.
Original starting rest voltage of each battery:
A = 12.50 volts
B = 12.52 volts
C = 12.495 volts
Total = 37.515 volts
Present resting voltage after around 90 watt/hours extracted:
A = 12.52 volts
B = 12.52 volts
C  = 12.55 volts
Total = 37.59 volts
Will continue the experiment.
