You are completely right. I found my mistake. I put a 20A fuse in the line from the main terminals. I don't know why it was blown. May be, that time the load was faulty configured in the maximum allowed current as well. So I charged that module to a healthy SoC. We will see, what we will do with it....

Summer is almost over and I came back to my conversion project. Today I was playing around with an 8S module . I just used it as energy source. There is plenty in it, I thought. ;-) But it seems at least this module is not much more than a brick. It discharged way too fast. When I looked at it after...

I have closed modules from LG. Kutato, great picture. :D This helps a lot! I guess the grey flex cable is from an 8S module and the pink one from a 12S module? So there are 4, respectively 6 fuses somewhere else? Also good to see one of the NTCs. Is the other placed similar, just on top of the cells...

Thank you Carel and Kutato for your hints! :D Carel, great to see such a module from the inside. :) Do you have the possibility to cross check, what is between the cells and the pins of the connector? Fuses or resistors? The minus pole of cell 1 can be found on pin 7 and 9, the plus pole of cell 12 ...

Thank you Carel for your offer. I gues I will use it, if I understand what happened today. :o I am playing around with a 12S version of such an accu module. There is this 22 pin black connector. It contains the 12 voltages and 2 NTCs. I expected 13 Pins for the 12 voltages. But the lower most voltag...

Dear all, I just registered to this forum because of this thread. :) My conversion project is at the beginning and I will use these accu modules from VW's MEB. I got a bunch of them. Mixed 8S and 12S. First I figured out the pin configuration of the 22 pin "BMS connector". I was also able ...
