Great product works great

This stuff works great with the spot welder.

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!
