I need to try this out! I highly recommend buying a 3S lipo battery for it. I have a 5000mah 130C battery that is very well suited to spot welding. Turnigy nanotech if youre interested. Theyre on hobbyking.
Try a motorcycle AGM battery with a CCA between 180-200A and you'll be amazed! This device has different revisions. The earliest, requires a capacitor mod otherwise even if you have a good battery, if the battery voltage drops, your mosfets will blow up. There is a newer version that requires a resistor mod for the device to work properly. There is also a "Wise Maple" version of the welder which seems to be perfect, but won't allow you to weld past 30ms. Remember, using a weak battery will create weak welds. Using a very powerful battery (CCA > 250-300) will EVENTUALLY destroy your device because the mosfets won't be able to handle that much current and both the PCB and the cables will overheat and become a source of resistance (which is bad)! LiPO batteries are the strongest, but they are often too strong plus they will explode or catch fire in case of an extended short circuit. Lead Acid batteries don't do that!!
@@solidhit2 Great info, didn't realize there were so many different versions. I think no matter which battery you use, don't do too many welds in a row without letting it cool off. This is a small, inexpensive devise so I wouldn't expect it to handle really heavy extended use.

That look so cool. I wonder what else one could spot weld with that little guy.

That's awesome. I'll definitely be needing a battery for it when I put my EVE cells to work, so thanks for the tip.
