Yes, that’s the easiest way to use the battery function in Hobdrive as the battery voltage needs to be below a certain level (can’t remember what exactly).

Yeah, I think that this is the Problem on my car.
Calculated SOC is not alligning with the cells voltage.
So I tried to get the car as empty as possible, but a low SOC might not be enough for the procedure to start.
Can I damage Something, like the car not accepting charging anymore when i let the heater run until it is empty and shuts down?
I will take a Screenshot of the voltages as soon as I get home from work tomorrow.
today it was at 51,8% an I wanted to try a second trip to work.i plugged the car in for literally two minutes, and now it is sitting at 71%.
I think the BMS is confused because the cells do not work as they used to.
Voltages are now at 4,012V and 0,01V difference

No, the low voltage protection will keep the cells in the ‘green’
Correct, the BMU calculates with the old battery’s capacity which doesn’t match the new one’s voltage levels
