Be carefully not to touch the outer foil of the pouch cell with your tabs. People experience short, if touched.

Ok I got it a lot closer to being hooked up. I ran a second ground wire to the battery output for the BMS ground. I realize I should have done the same to the positive for the charger⌠So I will attach another positive lead then wire it up to the BMS.
I regretfully did not test the cells as I assembled the pack with them, so this might bite me in the ass shortly. Weâll see, these are the one from battery hookup so Iâm hoping for good things.
update they are all at 3.7-3.8 but I donât have connectivity on the lst balance lead on the positive side 
Oh Iâm thinking about wiring up 4mm bullet connectors to that negative lead so I can remove the BMS after charging. Still considering how I would do that
^working on this is last thing im doing today
aaand I ran out of solder right as the hardware store closed.

I tried finding it everywhere but thereâs none in the US and they donât seem to ship here either - or do you know of a source?
Else, might you be so kind and order some on their page and forward it to me? That would be lovely!

If you got the right size the foil clamps are really easy to use, just need vice grips.
Although I am interested in seeing that method tested out more. Feel free to give it a go.
I just donât feel comfortable with those - will they hold up with vibrations?

I chipped a razorblade trying to pry it up just a tiny bit on ther edge. Then with a flathead screwdriver it took a large amount of force to pry it open.
let me grab a pic of what they do to the tabs.
Stronger than a spot weld. Plus, when âaccordion/zig zagâ stacked I placed foam in between the crimped terminals. This makes it so when the cells are compressed together the crimped tabs are âpulledâ apart because of the shape that the tabs make when pressed together. Pulling apart sounds bad bit it really makes better contact to the crimp I think as well as compressing the tabs together.
Let me know if this makes sense
The ones I got said rated same as 10awg but I did cut more than 3/5ths of it off so IDK Iâm only gonna pull 200A
I could actually probably add more pretty easily if needed. Easier with bigger vice grips. Big boys I had medium it was ok.
There are these really sexy wide ones that could go across the whole tab that look amazing. Get pretty pricey when ordering 100

That sounds good. How much current do you estimate it to be made for?
Also: which is the correct size? lol

I just finished making the new cell model with highly accurate detail on the tab. Fairly certain they are identical each side but should check.

this one is also too big, but at least two rows should have contact.
Who ordered the right ones?

So they must exist. But I wasted too much time on their page already.
@Arzamenable Would you be so kind as to let us know the part number of your clamps?

I might be interested too if you can find a viable shipping service and want to split costs.
So all the regular shipping services do support shipping batteries as long as they are declared properly. The issue is that parcel forwarding services donât support batteries, so would need someone to accept them and repack them for international shipping
Guessing the website doesnât support international shipping directly?
