Re: Total battery rebuild! Almost done - but help needed - solved!

Did you take any pictures / English language notes for this? I am looking at doing the same for my 2012, 8-bars 24 kWh Leaf. I'm looking at $3000 in 51 Ah battery pouches from Alibaba, I calculate 36 kWh final product. I've seen the Ukraine video:

I'm guessing you bought these?

(Or similar, 300x100x14.5mm)

I was considering:

(306*102*11.4mm)

And having some detailed instructions might help me figure out if that might still be able to fit.
