Did you spot weld the copper braid?
So you think 4 layers will be the safer way to go?
I think it’s excessive. But it depends. If they want to run 60A off a 2P pack, even with 4 layers that pack is going to have major heat problems.

Gotcha. Ok I will consult the builder and see what he is planning on. But yeah I was thinking the same 60 amps of 2p is a hot pack!
I know it will be a single drive build
I like to solder nickel. @BluPenguin details his method in the post just before mine linked below.

I would say 2 layers would lay 60A continuous no problem for maybe 10-15 seconds, 3 layers 30-45 seconds. Any longer and they need to consider 3-4P pack.

Right on! Thanks for all the input guys!
And go practice your glue gun skills. lmao

Lololol! Actually my wife’s head gun skills 
will relay the message tho
Another thing to consider is that nickel is a crappy conductor compared to copper. This is the reason why people make series connections with copper. Personally, I try to make the run over nickel as short as possible in the batteries I build. YMMV

This is a good point, perhaps I will just do single layer, and use some copper braid.

This true. It’s all about minimizing the distance from the cell to the copper bus.

I suggest 2 layers per P group, then copper braid or wire per series. That’s my gist of what I thought your plans were.

Just thought this was a funny size comparison lol
An entire battery worth of cells and 2p groups worth of cells

Please also know that is the guy who wants to boost a 1s to 12s. Lol. 
I have a hard time taking him seriously now.

One layer of nickel on half the pack for now, anyone else tape up their battery terminals while building? Lol constantly worries il set the battery on something and short it
