Juanjo Madrid's cell replacement thread

[piev]

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

Juanjo .. Boa Tarde ..

Tenho um MIEV 2012 aqui no Brasil e vou precisar trocar o conjunto de baterias daqui a algum tempo.
Você já recebeu essas baterias que adquiriu? E já instalou no carro?
Vou ter que importar também daqui a algum tempo..

Obrigado Adalberon

Tudo em paz ?
Obrigado pela atenção
Estou curioso para ver o resultado da troca das baterias.

Seria possível me enviar a especificação exata desta bateria e qual foi a empresa fornecedora.
Eu já vou iniciar as negociações de compra..

obrigado

Hi, the batteries was buy with the help of a friend with company in Hong Kong, around 2400€ in my House, I not pay transport because my friend buy Power bank to this company every two months and put in their container from HK to Málaga and send me to Madrid, I wait around two month to arrive to my House,, are the original LEV50N, the same model of the I-miev afther 2013, are used batteries around 37-40Ah measures from minimal to maximal voltage at 6 A current of charge/discharge, 1,3 mOhm to 1,6mOhm. Im balancing and tested now all the group and hope put in my pack around 20 days if the wheater improve. I put here the result of my test here. I unknow the supplier company, are Dismantling storages, not are manufacturer like you can see in Alibaba or AliExpress. Have around 12000 pieces, if my test and result are ok, my friend say me we could do import in Big quantities to improve the price (and profits), I think a good objetive could be 2000€ in any EU destination, more price is really stupid from the CATL 93 option is available.

The better of used LEV50N option is the lower price and this cells are the original parts, no need busbar mod, if you not need the double of the original range maybe is a good option for you.
