<p>It troubles me that this video is still up and running. Shorting a lead acid battery like this will not only cause the battery to fail in the long run, but it is also dangerous. A quote a comment from Youtube:<br></p><p>&quot;Shorted battery will overheat and emit hydrogen from sulphuric acid. One little spark and hydrogen inside the case will explode!&quot;<br><br>Dont try this! There are better, safer ways to make a spot-welder!</p>
<p>Hi, I really like what you've done, but should I be worried about damaging the batteries by using this method? I'll be using 26650 cells. Thanks. </p>
<p>I'm excited about this, because I wanted to spot weld batteries too. Prior to this, I thought you needed crazy equipment to handle the task. I hope this is safe to use on NCR18650 lipo</p>
<p>Hi what other battery could you use? And nice job!</p>
<p>I love it. Simple and effective. I can't wait to make one. My rewired MOT puts out just over 600 amps at about 1.3v. Now I can use it for more than melting nails, screws, etc. Fun stuff.</p>
