I tried disconnecting the ribbon from the bms to no avail. But perhaps I could have waited longer than a couple of minutes. I ignore whether the bms has capacitors that can hold current for a while. I will try again for longer, perhaps a couple of hours. My bms is sort of branded, but its laser engraved, making it really hard to read (apart from being most of it in Chinese). I had to take a picture at an angle to be able to read something. It also has a QR code, but my phone could not pick it no matter how hard I tried. I could verify that it's a 13s4p 48v 35a. I will take a look at it again to confirm whether it's a common or split port, although I am pretty sure is the first. Even if it's not the root cause of my problem, I am tempted to replace it for a Canbus/bluetooth enabled one, since they are quite affordable. Anyway, I am waiting on Chilli to provide diagnosis. One other thing I could verify is that the cells where actual Samsung 35E.
