A New Way To Deal With Flat Top Li-ion Batteries !

[dden4012]

Why is that?

Is he saying the nickel transfers to the battery? Micro electroplating?

Why is that?

How much amperage do you think that very thin flashing of metal on the surface of a magnet can it support ?

Remember we are talking about anywhere from 1 amp up to 5 amps +......



I remember years back (a lot of years) in high level R/C Car racing everybody was ALWAYS looking for a edge over the next guy so people would push the electronics many times to the breaking point which would almost always end with total melt down of the car leaving a person with not a lot to savage, the problem was always the same ! how can you push the most amount of amperage from the battery cells (which includes from between the cells) to the winding of the electric motor (with R/C cars back then that would be the rotating armature) and do so with the very least amount of weight (IE wire and or connections) ! ANY FLAW in a persons idea of how to best accomplish this would in ALL cases lead to total melt down and a very sad someone picking though the pieces to try and figure out what failed first....... You learn A LOT from that sort of thing......

Tests have proven it can support at least a few amps. Are you even reading your own thread? Have you tested it yourself? Please provide evidence that magnets "won't last for long" at a standard current, or kindly shut the f:yh:ck up.

Your trend of making claims in areas you know little or nothing about... needs to stop. We've all got better things to do that continually disprove your bullshit. Knock it off.

Probably as much current, if not more than the thin metal on the driver PCB that's running the diode?

Or, have you seen the hair like filament inside a 5A glass fuse?
I'd think that these neodymium magnets have at least the same amount of surface area, if not more, than one of those fuse filaments. :thinking:

I have every right to express my opinion as the next member and I will continue to do so but without obscenities.....

Well express it as an opinion then, not as a fact.

Cyp is correct...

I've never used the word fact in any of the posts in this thread, your making an assumption....

I'm making an assumption am I?

Now setting all that aside for a moment, There is one more thing that no one here seem to be aware of which is a little known fact and word of warning for anyone that uses a neodymium magnet as a conductor of electrical current between two Li-ion batteries, Neodymium magnets should never be used as a conductor of electrical current because the electrical resistivity of the magnetic materials used is relatively high, The conductivity is about 1/50th that of copper which makes it a very poor conductor of electricity !

:crackup: :crackup: :crackup: :crackup: :crackup: :crackup:

You're making this easy. Think before you speak.

Oh, and FYI, I just ran 4A through one of my magnets for 5-6 minutes. Not even warm.

What am I supposed to be looking at here?

And again, from my previous post:

"Oh, and FYI, I just ran 4A through one of my magnets for 5-6 minutes. Not even warm."

I'd be quite confident in its ability to handle 10A for shorter runs.

Edit: Even with a big heatsink, good batteries and an efficient driver you'd be running into issues with heat at those run times at those currents, and not from the magnet, but from the LD/driver/batteries.

As always everyone is free to use whatever method he choses, I myself will not be using magnets......

Exactly... we are talking about 1-5 amps in our Laser Driver
use.

Not the 50 to over 100 Amps in R/C Car racing requirements.
Not to mention the the extremely high constant current surges
when the throttle goes from Zero to Max many times during a
race.

Apples and Oranges....

As always everyone is free to use whatever method he choses, I myself will not be using magnets......

Then don't use them...
Why keep trying to prove that because you don't use them
for driving Lasers we are wrong to use them...:thinking:

I'll tell you what smart guy you send panasonic li-ion battery tech a email stating your going to use a neo mag as a conductor between two of their 18650 Li-ion batteries and if they say Hey that's a great idea i'll shut the #%@$ up !

But if they don't.......

The obvious smart guy that needs to swear because he
seems to be frustrated by not having a leg to stand on
is you....:tsk:

The link you posted above is the same rhetoric you spew
here. No facts just random theories about magnets...

Read the Neodynium magnet resistance specs on this link...

Still waiting on that response from panasonic li-ion battery tech.......
