Hi all, Hi mike, i would say, the meters have been keeping a better recording.
Also, i will defer to joseph newmans terminology, lucs setup gave 135 watt/hours of obvious usable work so far and 135 watt/hours or so of not obvious work, which is the unseen charging done within the 3rd battery.
peace love light

Yes BroMikey

Unfortunately it looks like you have it right

Since your calculations comes close to the motors watt meter, then I would also support that the meter Ahr reading may be a true reflection of the power that has gone in the motor.

I resumed the test at 9am but I don't think it would run any longer then a few hours.

135 vs 120?

Okay guys correct my math if this is wrong please.
...

Yet Luc's meter is showing that the motor has had 135wh go thru it
when theoretical for for 2 five amp hour batteries can never exceed
the 120 watt hour mark.

I am sort of puzzled at this point.


Anyone thinking this thru?

The 120Wh is nominal. (12V * 5Ah * 2 batteries)

Maybe actual voltage is a bit higher on average.

At low C-rates, batteries can output higher than the C/20 Ah rating. Maybe up to 5% so I've heard.

Wattmeter accuracy may be questionable at such low current. 0.14A is 0.7% of full scale Amperes.

It will be interesting to compare to the one (or 2) battery test with the same load (0.14A).

For the $12, I think I'll order one of these Wattmeters and run a few calibration tests against some other meters/testers I have, like the CBA II (from West Mountain Radio).

{edit}
I think most of the extra Watt hours come from the first 5 or 6 hours of the test where the motor voltage is high, starts out at 16+. So current is higher and power (W) is higher and Wh in the motor (system load) accumulate faster. At first battery swap, at 6 hours, there is 33 Wh shown for the motor. Using nominal or average numbers one would have expected about 10 to 12 Wh.

Updates

The test ended today at 10:20 am and Motor Wh meter total was 135 Wh.
The final video will be available once upload is complete.

Also, I've received Carroll's "Matt modified motor" so we can begin tests once I've established the Wh capacity of the new batteries.

Thank you Carroll for your help

at times and many folks have experienced it, Some have managed to amplify it by trial and error but I don't think anyone would disagree if I wrote 'No one has nailed it down', - That is to 'an explainable specific' in short The effect is being amplified and utilized whilst the cause remains unknown.
That doesn't mean that when someone eventually does (and I'm sure it is 'when' and not if) I doubt it will be because they are more persistent, cleverer or built more motors I rather think it will be some one with some little and unusual plus in their skill set , a little strange niche or experience overlooked by most.
I guess really every bodies rooting for you to spot the missing link, (for all the *****ing here and there) As far as I'm concerned Its a new pair of eye's and hands with different test gear and different skill set , something new can happen anytime . Believe it! Its exciting ! Particularly as I Have read and watched a lot of your work over the years Luc . I will refrain from clutter on your thread as you run your tests Luc, however When I return from Budapest in a weeks or so's time, I have some four year old untouched gel cells and I'll have a gallant attempt to recreate that huge energy gain and icing on camera for you . There is no mistaking this visitor when it comes a visiting Kindest regards Duncan

Thanks for your post Duncan

I wish you a good trip to Budapest.

Looking forward to see the test of Ice forming on the battery when you return

Testing to see how much current the Matt Pulse Motor needs.
