Hello,Hello,
Please note that piev is the organizer of the traction battery upgrade effort and has consulted with many folks to get to this point. My son and I are now benefiting from piev's efforts. Our car's upgrade is performing as expected and we are very pleased.
My son is working on some documentation on "Pack Removal, Module Rebuild, and Man in the Middle." The first version of "Module Rebuild" is complete and may be found at:
https://5by9.net/prune_batteries/moThe first version of "Module Rebuild" is complete and may be found at:dule_rebuild.html
I will post notice of the other sections when they are available.
Our thanks to piev and all the other people who have contributed.
Mike

These may be different than Mikes but these are the measurements I made.Hi Michael,
Nice write up! Thanks to you and your son for making this.
Would it be possible to PM me measurements of the jumper tab below by marking it up in MS Paint so that I can have it quoted at Send Cut Send? I've made ballpark guesses below. I will change the numbers and repost when I get the measurements. Also, what is the thickness of the jumper?

Jim,Hi Michael,

I will change the numbers and repost when I get the measurements. Also, what is the thickness of the jumper? Rule of thumb is that thread engagement (for the 3mm-.5 screw) should be 1.5x diameter of fastener but more if material is soft like copper. This isn't gonna happen but 3mm might work OK. PCB busbars would be better.

Very cool. Thank you. May I ask what the CTC distance is on the cells you used? Based on what you have here your cell's terminals have different centers than Piev's.Jim,
I'm posting here since others may be interested in my drawing as well.
It will also be added to the document at:

The bus bars were chosen to be cut into a jumper and the remaining
piece used as a spacer to allow the inter-cell jumpers to be level.
However, the M6 slots needed to be re-worked to M8 slots. The bus bars
were purchased on Amazon:

We were only doing one car, so the the effort to hand cut the jumpers
was less than doing precise measurements, getting samples, and perhaps
repeating until we got it right. Only a few of our jumpers needed
re-work.

If you look at @phebbler ’s design back in post # 236 you’ll notice “C” is not required, it’s just another “B”…Welcome back to the Jiminy show.
Here is a possible way to do all of the bus bars that eliminates the stock bus bars entirely. I have not modeled the daughter board to the CMU so this would require refinement when I do but you get the idea. Bus "C" requires your imagination as I have not added it into this assy. It forms a "U". Best guess is that the whole pack would take 24x A bus bars, ~66x B bus bars ($[email protected] Cu on SCS), and 10x C bus bars.
