Juanjo Madrid's cell replacement thread

Don’t think the BMU is VIN coded, otherwise below would not have worked:

Afaik VIN programming is only required for ETACS-ECU, EV-ECU and MCU..

You may be correct. I do know that it has information in it like serial number and model number software version etc. I would have to look it up because I can't remember specifics. Of course, I don't know if the ECU uses this information, so it may work to swap them. Maybe I will try it next time and see. I just finished my second upgrade. Did the whole thing in less than 20 hours.

It does work, see post #225

Do you have dimensions of these cells to share? Do they have the threaded holes for the CMU boards to mount?

This drawing is started to see the difference in measurements between LEV and CATL because my plans were to use 2 LEV50N and 2 CATL93, I'm not sure if the measurements are correct because in the middle of this, I saw all the measurements on this forum and I remember mixing my measurements and the measurements on this forum.

I think the LEV50 and the LEV50N are the same, but I'm not 100% sure. The only thing I can tell you is that I thought the LEV50N was perfectly fixed in my packs and there was no problem with the CMU fixing on it, I had to make the separations between cells because my LEV50N had nothing to ensure they were pressed and I transferred the originals to the LEV50N, I put some photos of my mixed LEV/LEVN cells, the differences I observed (height) I attributed to the use and possible inflation of the old ones
