SHONAN Pure Nickel Strip 99.6% Nickel, 2 Inches Nickel Strips, 0.15x6x50mm Soldering Tabs for High Capacity 18650 Lithium Battery Pack, Li-Po, NiMh and NiCd Battery Pack and Spot Welding, 50 Pcs

Great quality and appears to be pure nickel. Used these nickel strips with a Docreate LCD Spot Welder-797 also purchased here on Amazon for roughly $30, and had no issues at all.

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.

These get the job done for the size and thickness they are in my DIY electroplate bath. There is noticeable nickel sulfate residue from the electrolytical breakdown of the nickel substrate. Seems like a lot to me. The strips are 99.6% pure nickel and a quality/price/size that worked for me. I am using 4-5 volts and maybe 800milli amps of power which seems to work well. I did not want to spend more $$ for a heavy duty nickel rod for my simple purposes and these strips, even if you have to change them every 3-4 hours, do the job.

I am using this to connect 14s 125a 12700 cells that are pulling 240 amps or more on rc aircraft. I did double up the tabs. They weld up perfectly and stay barely warm. Good stuff!

All right I will list my ideas on durability. It’s a strip of metal so I imagine it’s pretty durable. Next the size. You know what you’re looking at you know what size you need. Functionality? It does exactly what it’s supposed to do. It’s very easy to use. Just unroll how much you need and cut it. The quality. It’s fine. It’s a roll of metal. And value seems about right on. So enjoy your nickel strip.

Looks pure and measures at .2 on the dot. I have nickel coated steel and this is not the same.

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!

Worked as needed to build 18650 battery pack.

good job

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.
