Are you sure that ar 88cells ?
I know that C-zero have only 80 cells

C-Zero/iONs equipped with the improved LEV50N cells have a 80 cell pack, but all triplets built pre 2013 (ish) were using 88 LEV50 cells

Yes I'm sure, my C-Zero is from 2012, I connected the ION app and I read 88 cells.
In fact the battery pack of my C-zero is 16KWh unlike the 80 cell one which is 14KWh.

Didn't know that. Nice to learn it

First of all, there are many threads already here about this type of endeavor.
I was asked to start a thread on my project. I must say I couldn't have gotten this far without all the great posts on this and other forums.

I have had a few setbacks but won't bore you with the details.

Current state of the project:
New battery cells 93Ah NMC are installed in the vehicle.
Range was reset with MUT3 SE using windows driver by kolyandex to 45 Ah.
Current range 66 miles.

I accomplished this last year but then got in an accident and had to find a new car to finish this project.
When I moved the battery pack to the new vehicle I had a bad temperature sensor on one CMU board and the vehicle would not go over 35 mph or charge.
So, I put a CAN bridge between the CMU and the BMU to fake the data for that one sensor.
I was able to charge the battery to full and it drove normally.

Hardware:
I used an Arduino Due with a Dual CAN Bridge made by Daniel Kasamis from ~bit TOGGLEBIT.
The Cells I used I bought from Alibaba. 93Ah 3.7V nominal charge to 4.2V
They also sell a 75Ah that will fit in the original space.
I paid around $70 a cell with shipping to the USA from China.

One thing I didn't notice was the size of the terminals. they were M6 and the LEV50 had M8's. The sales rep said they could change these but I already had the cells.

I will add posts as I think and decide what would be useful for people that want to do their own.
