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

I used these for a small nickel plating project and didnt want to spend a lot on something i never tried before. They worked great! I made a pint mason jar worth of solution with 6 strips. I've another 3 to help plate a pair of pliers and a test pieces. I can see the 50 strips coating many items

Easy to solder

Worked well for making nickel acetate for nickel electroplating. Bit of leftovers in the bottom but that can easily filtered out.

As stated as sold no complaints

looks like good quality so far

As described.

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.

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!
