This is 25mm folded over and 37mm for the full side, I think 50mm will work really well, you’ll probably have extra on the top honestly.

If you can get your hands on 50mm nickel yeah. That would work well! And also send me some lol

Cool! Got 5 meters of the .2 thick stuff on the way then. I’ll send you most of what I don’t use (likely a bunch lol).

see @ZachTetra… that is almost eggzakery my weld dispersion pattern…
EDIT:
I do know how to size nickel and make corners… so I usually have more nickel to hit… but yeah… that’s basically it…

Dang that would be legit
I’m going for that distribution. In my head I have to, in order to spread the heat out. Also when you have ~750 welds in a pack I can’t wait 30 seconds between each one.
The weld pattern on here gives me anxiety and pisses me off

I just jump between cells, after 5-7 welds it overheats the battery leads so I do other stuff like add insulator rings, glue cells, prep the holder, and cut fish paper

Here ya go
0.2mm x 50mm 99.96% Pure Nickel Plate Strip
It has plate in the title but otherwise indicates that it’s pure nickel, looks legit.

slight tangent - those of you who build packs for others how do you deal with potential liability? I like the process and am considering building them for friends one day, but want to research whether it might be cost-prohibitive with insurance and whatnot.

I don’t think they really can put it on you, it would really be their “misuse” or use at all of a pack that causes it to go kaboomy.
Basically it wasn’t on fire when they sold it to you so it isn’t their fault, legally, maybe.

yeah I’m thinking about a situation where their misuse causes an apartment building to burn down killing small children and them using some legalese mambly-pambly to pin it on me somehow. I’m not even remotely educated on the legal system so that’s why I ask.

I know neutral cure electronic silicone is a standard adhesive/insulator for battery pack construction. I believe it’s a solid splooge option for exposed terminals on P-groups.
How about liquid electrical tape? I feel like I’ve seen it used on P-group terminals in pictures.
Asking here, sorry if it’s off topic.
Who can recommend a good seller of Aliexpress for battery cells?
Looking for some 30q’s
Thanks,
Dani
