I thought I was building a 72v battery but ended up a solid 12.

I was confident abdI thought, “I don’t have to draw anything out…diagram, wateva. “

So this 12v battery was suppose to be a 72v pack. I think I need to solder my way out of this mistake….without disassembly. Is there any hope? Wires all crazy looping around it would look cool. :)

So, in short:
• while I was making this battery, the ends of the cells are becoming very thin and leaking. I would say every 30th weld - that means ripping it apart would leak every 10th cell with joe I saw them struggle.
• I’m hoping to use this battery as it sits shape wise.
• I think I’m going to need cut/separate the nickel.
• I don’t mind a safe yet performance thin and inefficient pack.
• if I had to rip it apart, I guess I would just leave the rough nickel slabs and load each one up with solder and wire it up.

But any ideas?

Thank you!

yeah, looks pretty solid. Maybe just leave it as a lesson learnt and move on.
Or add missing 16 layers around until you get to 72 V

It looks deadly. The welds don't seem to hit the cells at all sometimes, sometimes at the very edge. In addition, you yourself say that several cells are leaking. The recycling station is probably the most suitable.

The leaking cells were removed. The quality, well, that day was a very skimpy day on nice nickel.

So okay, a vote on kick to the curb, and thank you for zooming in.

Now that I look at it, maybe you’re right all the way
