  At last, someone who reads the notes and watches the Vids,  so many reviewers using the wrong batteries, not just back up batteries, thanks for an objective review...

  In all my years of watching thousands and thousands of YouTube videos, I have never left a comment but this little video deserves a comment. I found it very interesting and like one of the other comments stated I think this explanation and logic behind it is spot-on. Well done and thank you.

  OMG, you&apos;re my friggin hero!<br><br>So, I bought these little battery powered spot welders off Amazon, and was super excited to test them out. They have decent reviews, so I was expecting them to work. They&apos;re similar to what you&apos;ve got there, but different in the fact that they have their own internal battery/power supply.<br><br>I have tested them over and over, medium strength, max strength, thinner nickel, still I couldn&apos;t get a proper weld to save my life. Even when the strip stuck, I could easily peel them off, no good at all. I was getting pretty sad, about to just give up and send them back to Amazon, but I decided to do some more research first...<br><br>In watching your video, you just hit the nail right on the head for me! I was pushing really hard, and even harder when it wasn&apos;t working. I was trying my best to get the probes straight up and down as well, thinking that a nice firm, solid contact would be best... Jesus, was I wrong!!<br><br>I decided to try your advice, pushing less hard, using the corners of the probes, just being gentle with it... For the first test, I also turned the power down to a medium range. Holy sh*t, what do you know, after trying and failing dozens of times, I just got an AMAZING weld for the first time!!!! I can&apos;t yank this strip off at all, it&apos;s on there gooood!!! 😊😊 I am so happy man, thank you so much for the informative video!!

  You&apos;ll be fine going over mah. What matters is the discharge rate (50c on the lipo / CCA on the car battery). &nbsp;If the battery can&apos;t discharge quick enough, the voltage will sag and the mosfets won&apos;t fully turn on (saturate) which can cause them to heat up and let the magic smoke out. &nbsp;Mosfets have a spec called RDSon which is a curve of resistance as it relates to gate voltage. &nbsp;When the battery can&apos;t discharge quick enough, voltage drops so the mosfet gate voltage drops, and resistance through the mosfet goes up. &nbsp;Resistance &nbsp;= heat = smoke. &nbsp;Good video by the way and good explanation for people aren&apos;t familiar with electronics
