I'm still looking for it lol.

And this isn't technically based off of it.
This was an independent thought.

But part of trying to invent is making sure someone else didn't invent it.

And I found several that refer to this principle, but one really old one that was the same save for the axis.

The closest I've been able to remember,
Is that it was some sort of electromagnetic stirring of the electrolyte solution for lead acid.

So I guess in principle it isn't like what I'm doing here,
Because the electrolytes in a lipo aren't liquid.

But the application was the same,
An electromagnetic field around a battery.

Or the simple answer... warm your Li-pos up! Hey presto, lower IR.

60% of the time, it works every time!

there are those cell phone induction chargers that have the coil housed within a slab like box where the coil is flat, different but similar in another aspect.

here's some real info relating partly to what is described http://spectrum.ieee.org/nanoclast/...ectric-vehicles

Please start reporting battery temperatures at the time IR is measured.

I am not buying this magnetic loop whop de doo what so ever.

"Sure - - - but within the metal of the pipe walls - - - not in the open space inside the pipe. "

Agreed...

But, an electromagnet can be made such that a strong field is present without a coil.

So these experiments can still be investigated by changing the method of creating a magnetic field.

Ok
I was able to get in a flight late last night
The batteries have sat for 24 hours

I will temp them before charging and after.

But keep in mind,
In asking for all this additional "proof"

You're still taking my word for it that the numbers I'm presenting you with are accurate and not misrepresented. That's why I wasn't concerned with presenting the additional data. Because,
I'm not selling anything.

I expected,
That anyone intrigued by this would try it.

New 4s
no EMF boost
1st charge of day (24 hours since discharge)
74.4° before charging


77.1° after 21:53 in charging

new old that doesn't matter more than one lipo charged normally and all vitals recorded and then a charging WITH the coil of a number of winds with so many thou of wire around what diameter and the resultant permitence of amps, the temperature of the lipo before and after, the time it took with and without the coil, the state of magnetism inside the coil, and a partridge in a pear tree (nix that last part).Also, the state of charge before and after.

Magnetism is the realm of attraction, repulsion, polarity and flow, orbitals and light.

So the battery that began here
(Bought used unknown cycle count, 6 cycles by me before this)

Ended here with a 24 hour wait before charging.
Charging with no emf boost

so what are the vital results of one lipo without and with and the engineering specifics of the "booster sauce".

And the new battery that began here
(6 break in cycles only previous activity).

Ended here
Never having been exposed to the EMF boost

My opinion is that this doesn't demonstrate anything really...

But I'll have more in time

I have no doubt that your observed numbers are exactly as you present them.

That's not the question.

More test parameters are necessary to adequately evaluate the presented numbers (like pack temperatures).

Sounds like a detailed test plan is needed.

If you have no interest in trying this,

Then why are you here?
Oh wait I'm sorry we've established that.

I can show you all the numbers in the world,
But they are meaningless until you do it for yourself. At the end of the day, you know nothing if not acquired firsthand.

I still haven't found the old patent but I have found this.

https://arstechnica.com/science/201...y-work-magnets/

They are aligning the batteries as they make them,
But the principal of magnetic alignment for increased performance is the same.

Ok...

But who's "we"?
