Battery help. Swapping cells is all I can afford and doing it myself.

    That number 3 dropped very fast just leaving the car in park with nothing on. Screenshot_20220722-185121.jpeg

    Well, there you go. It looks like one of the modules in block 3 is bad. So far, every thread I have seen for the past 2 years that had a block voltage difference of 1.0-1.5V turned out to be a failed module.

    Looks like No. 1 is also failing based on voltage and IR. Change it too.
    The IRs of the rest are creeping up as well.

    Changed the bad one on 3, it was 6.5 when I pulled it. Also 1 in number 1 and another in the last block. Both at 7.7. Everyone now is at 7.8-7.88. The hack that worked on this last left 26 of the 28 bolts out that held the cells to the bottom. Other shit he left disconnected too. Like the leak tub and the battery return air. Just blowing out next to the battery .

    The cable connector to that corroded one looks bad too. PXL_20220724_213806823.jpeg
