any way to create packs without soldering?

Nice little DIY setup ya got there.
The reason you have to recharge so often is because you are using the lawnmower battery, and something that is 300CCA range.

I would recommend going a little further into the project and build the proper timer adjustments with the FETs and triggers so you can use any battery and really dial in the duration needed.

Thank you sir and, yes, agreed, for big packs or any type of consistency, I definitely need to get some type of timing integrated into it. This is the part where I wonder if it's worth it taking the time to source and learn everything or if I just roll the dice on the sunkko 709AD version that's currently in the marketplace board. Only have 110V plugs though so kinda concerned about that since everyone seems to say that version is real weak. I can't seem to find the kweld in stock anywhere either so we'll see.

That's definitely good info, thank you. I didn't even know about the malectrics unit and seems like a lotta people on here like it. I'll be checking that out for sure.

what do you guys think of this unit below?

Its a locally availableproduct soooooo thats heaps cheaper than the other options for me... thoughts on quality?

I don't think I've ever seen an AC version of an arduino spot welder before, that's really cool actually. If it's available locally does that also mean you can return it if it doesn't work? Cause if so I'd definitely test it out myself and give it a shot at that price. Admittedly I don't know near enough about components to tell if it's worth its price yet.
