SHONAN Pure Nickel Strip 99.6% Nickel, Nickel Strips for 18650 Soldering Tab for High Capacity Lithium, Li-Po Battery, NiMh and NiCd Battery Pack and Spot Welding (0.15x8x100mm, 100pcs)

This is in my opinion the perfect size and weight to use for my battery 🔋 can't tell you that it's nickel but it looks like it is. It's good quality anyway. I think it will have great performance and transfer more power. 👏

I cut off some long strips and folded then up to make electrodes for nickel plating. They leave a black grit in the solution that can be filtered out but this is supposed to be normal. Otherwise, my solution stayed green as it should and I was able to successfully nickel plate my parts.EDIT: The quality of your nickel plating really comes down to surface prep and controlling your current flow. I also used 99.9% nickel which left less black debris in the solution, but literally made no difference to the quality or appearance of the final finish. This product is thin like foil and no matter how you fold or ball it up, it quickly disintegrates where it enters the solution and falls off, which breaks your circuit.If you don't have a power supply where you can control current flow, just remember more anode surface area you have touching solution, the higher the current flow. Too much current flow and your nickel surface will form too fast and be rough or look like tiny craters. Not enough current flow and the plating takes too long. Error on the side of slow.

The media could not be loaded.  Very good product and good quality and package

Nice product.. clean strong welds.. worth the money.

I used this for a moving contact and it works perfectly.

Great size perfect for battery pack builds and they weld very nice with spot welder have a strong hold for what it is. I will be getting more for my project

Product is as described. Shipping was fast. Very happy with the price. Would recommend this to others.

I cannot validate the authenticity of this product for pureness as I have no means to test it so.. I will say these "so called Pure" Nickel Strip 99.6% Nickel, 0.15 x 6 x 50mm for 18650 batteries Soldering Tabs were okay for building a Lithium Ion battery pack as I do not have spot welding machine. BTW, These are very thin and cannot handle huge amount of current draw. I think each fine strip it is limited well below 6-8 Amps current draw per group of cells. As long as you understand the limits you should be fine.One of the battery packs I made I found these single strips would heat up during battery pack charging process so I had to double the strips to keep the series parallel junction cool. At about 20 cents each these aren't that cheap and mere 50 pieces gets used up pretty fast when you are building a battery pack.The good news is that soldering the tabs works just fine as long as you dab them generously with flux and flow solder at good high temperatures for short duration. You do not want to heat-up the battery posts for too long as you might ruin them permanently.Rating them with three stars!

After seeing all the negative reviews all over Amazon, on items that claimed to be pure nickel that later turned out to be nickel plated steel, I'm happy to report that this one is genuine pure nickel.Did the salt water test for 24 hours. The one on the left is the nickel. Right side is a test peice cut off an old battery (plated steel)Another thing to note... Though nickel is not a ferrous metal, is is however ferro-magnetic. Meaning that it will be attracted to a magnet. Some reviews I saw claimed strips were not pure nickel as they would stick to a magnet therefore must have steel in them. Generally true for other metals that aren't ferrous. Like aluminum or copper. But because nickel is ferro-magnetic, magnets will still stuck to it.Cheers

Es un producto listo para su uso, de buena calidad

Product exactly what I wanted. Delivered quickly and fairly priced.

Bad products

I would have to say this is real nickel as I've tried so many different kinds and tested them all and this is the only one that does not rust nor spark when I grind it. What I've found best to do is lay some of the roll on a 2by4 then then with my dremel , grind in little slots then cut to length so when you spot weld or solder it works much better so solder will fill in slot and hold much better and when you spot weld put a probe on either side of slot and away ya go.
