What/where to get copper wire.
#1
Sorry for this question, but i am losing my patients.
I tried tinned copper wire, bare copper wire, 0.5mm copper wire ect
NOTHING...that suits my demands.
Probably i am searching the wrong way, after 3 HOURS still didn't find what i was searching for on ali:
Simple 0.5 mm (or similar) BARE COPPER WIRE or tinned wire on a coil or something.
I need 5cmx25 per pack x 14 packs x 10!=200 meters if my calculations are right

What copper wire do you use at the neg side of the cells?
It needs to pass a 100mah per cell.
How do you get copper wire the alternative way, strip wires?
What wires?
Just want to buy a coil or something.

Sorry but i just had to blow off some steam also, probably will regret the setup of this post tomorrow.

Thanks for understanding, thanks in advance for a answer

1400 cells in packs Exclamation above 2500mah and 90%soh.
~400 cells between 1800-2500 and above 90%soh(sell?)
600 cells between 2200 - 3000mah, 80-90%soh (sell?)
2600 waiting for testing.
approx: 500 cells not safe for use: dead, heaters, to high ir or sd

I thought you were going to say Outer Mongolia - there'll be plenty of electronic suppliers in such a civilised Country as yours.

Civilised Country as yours?
Euh oke, your welcome to stay and i show you around, where are you from?

But i drove to a "old fashioned" electronic supplier, there are not much around here anymore and i wanted to be lazy and cheap.
But "Klare" In Zwaag had what i wanted and cheaper than alibaba?!?!?!?!?
I ended up with 0.8mm tinned pure copper 50 meters wire 0.5 ohm per meter wire, for 5 euro.

I also think(know for sure 95%) he is one of the LAST old fashioned electronic supplier here in Holland.

Thanks for the wake up call.

I may be late here already. Look for UTP CAT5 cable. Regular Ethernet cable. It has eigth 0.5 mm ( or less) copper cable inside. Give it a shot, it may or may not be your solution.

I just noticed this. I think you mean 100mA, not 100mAh. If the latter, that's a very very shortly lived piece of wire. Wink

btw, a wire that will blow at 1A is sufficient for using as a fuse for cells. The fuse at this level is not to limit the cell's delivery capability, but to limit inrush current if the cell short circuits itself. So even if you had a fuse that could handle 2A, and the parallel section was 10p, then at least 10A would be produced. So a 2A fuse would pop very quickly.

You don't want to use a wire too thin, otherwise you get too much resistance at normal, or surge, currents. This resistance heats up the wire, and will cause it to fail randomly, instead of under a fault condition.
