Just got my kWeld set up and did my first two welds
How do they look? I didn’t try super hard to pull the two strips apart but they seem to be quite stuck together, the strip onto the battery left two little circles of nickel when I pulled it off.

haha, those look good! Is this your first welder? I just upgraded to a kweld and the welds are outstanding.
anyway, I always tell people not to do this, but here I go, anyway. tearing down used packs to make another battery

First welder yep, default settings (50J for 0.2mm nickel), first two welds. It was pretty easy to set up and I went from kit in the bag to welding in about an hour.
I am going to be re-using some cells too lol but I have a good idea of their condition. It’s gonna take a while to dremel off all the little bits left over on them before I weld though
Obviously this premium price on the kWeld is quite steep, but to me it is worth it and I will probably end up writing it off as a business expense at the end of the year, so I just considered it an investment.
$235 for the welder and then $80 something for the battery from HobbyKing
For the supplies, the nickel I bought was like $17 and then I just got all these for like 8 bucks from Ali:

none of that for me.
I’m tryna go wholesale here 
put a disc sander thingy on a drill press, hold the cells with two hands, waaaay easier

Yeah haha I saw that contraption, unfortunately until I get more space I can’t pick up a drill press lol
The dremel isn’t too bad, but 10-20 seconds per cell x 60 adds up

Real quick. What are your favorite widths everyone for nickel larger then 10mm. Having some cut tomorrow / china time. 40mm, 20mm, ??

It’s a labor of love to reuse cells like this.
160+ cells ripped from a perfectly good pack and tortured on the sander. only to go back in the same holders…

Finally the day came. I rebuild my Raptor 2.1 Battery… Matter of fact this is my first completely new battery built ever… I might need some help with the Smart BMS later.

Why are some of the cells different…?
On the old battery the one on the right I used my old electronic cigarette batteries to see if the board worked on it… Plus those were my first K weld spot welds. On other threads people to me not to do it but I just wanna see if it fixed the problem.
haha, you coulda said “it shipped like that” and I would have believed you

Honestly, are you guys always get a happy feeling when you do the negative post because she got more room
completely novice analysis here checking my knowledge.
In this setup does this mean 4p * 15a 60A series current through the single strip of nickel to the next p group? is that a concern?
