Your cells in your diagram are fine where they are, just remove the connections. Connect each group like you do in the top column. If they are touching connect them.
Then run an extra insulated wire all the way back from the bottom left negative terminal.
Draw the new diagram first before you do anything, have us look at it, and you won’t have your home burn down probably.
Maybe
Diagram is fine. As long as you insulate the packs against each other and ensure that the overlapping series connections aren’t at risk of shorting against each other, should be sweet.
My personal approach would be to try and make those connections without overlapping, or at least using the gaps between the groups to try and get underneath the side to side connections.
You’re gonna have a hell of a time with the balance wires 
Edit: when insulating between the groups, i’d suggest rolling the fishpaper over the top of the nickel a little to mitigate any chance of arcing between the groups
Posting my first battery. I’m sure I’ll catch heat for breaking a bunch of rules, but that’s why we are here I guess, for the red circles. What a mission. I have to hand it to the proper builders in here - your work is stellar. This shit is not easy.
That looks great! Not many copper connection esk8 batteries around!
My dude that’s a really beautiful pack. Such clean balance wires.
Just finished making a 4 layer sandwich of insulation between everything.
I also re-routed the wires so nothing is overlapping.
I may need another quarter to half of an inch more of closed cell foam, would this stuff work?
Thanks bro. Time will tell whether it was a terrible idea 
Cheers for the 3d printed cell holders for the glue stage. At least that part went smoothly lol.
Thanks, took way too long routing those wires 
Nice! Where did you source the copper? And how thick is it?
The series connections are a bit overkill imo, but better too many than too few, so yeah. Use some clear heat shrink, would be a shame to hide this work!
Just comparing your packs to the tutorial pictures you posted, there is a lot of p group isolating fish paper that you didn’t use. Look at how much extra there is in the tutorial on the center and lower groups.
Ive used similar foam weather stripping rubber and had two different types come from the same order. You want the hard stuff not the soft stuff for that imho. Just keeps everything in place better and doesn’t compress as much when you shrink it up. BUT it doesn’t replace the fish paper. Fish paper is cheap and good at its job, go to town with it.
The design you have is inherently flawed and although as Al pointed pointed out, the pack is salvageable, you should really have run your design by everyone for feedback as I don’t think you have the requisite knowledge based on what I’m seeing above. Reorientating your cells to a "north-south’ arrangement and going w the ‘Snake’ style series connections would be much safer.
And I have to also say that considering I sold you the kweld with which ur working, I feel compelled to tell u that when you bring a flawed plan here and get feedback that’s there’s problems, it’s VITAL that u listen to that feedback. You can and will start a fire with what you’re doing here. Liion battery building is not a joke and treating it so flippantly is going to get someone hurt and is going to fuck up the hobby in the GTA bro and maybe in Canada as a whole. Look at what’s going on around the world. They just put forward a plan to ban storing EVs indoors in NYC.
If you’re part of this community, you have a responsibility to take care of it. Do better, homie.
This is the way. Don’t take common good’s and others criticism harshly, it’s all just to try and save you from making our same mistakes again. Making your own batteries is super rewarding but inherently risky. Not just for eskate but LIon batteries can easily be restricted to sales to businesses only or something worse and kill the whole hobby.
The packs we make are huge, high voltage, and subjected to brutal punishment and abuse. Failure is inevitable but the mode of failure can be somewhat focused to less news worthy means if we share our missteps and collaborate.
Also the sudo standards that have become prevalent on this forum seem easier imo to build than a lot of the stuff i was trying before I started lurking here 
Why not do it this way? Then you don’t have to worry about insulating the nickel connections, and you don’t have to rearrange anything, just resolder a few series wires.
This is how I normally make 3 row batteries
The long wire gets siliconed in the valley between the middle and outside pack
Are cylindrical cells prone to liking being vertical or horozontal more than the other? Going to make a brick pack with a custom enclosure and trying to plan it out smartly. Just wanted to know if one way or the other was going to make any difference. Cant seem to really find much online about the topic.
Yo this is post #21700 lmfao. good thing you used them!!
The copper is 0.2mm thick, picked it up from Aliexpress here:
Agreed, 4 wires is probably overkill. 3 (16AWG) would have been roughly equivalent to the usual 2x14AWG used by most in here, I think. Added a fourth for balance or OCD perhaps
I’m guessing the nickel is 0,1mm?
