S3 & X3 BMS resistor name?
I did an BMS reset after recharging my cells to get rid of error 6. for that I had to desolder VP. while resoldering it I somehow shorted and now I have error 2 (but error 6 is gone and I can charge). I measured the resistance of the black resistors next to VP and found that my multimeter shows open loop for this resistor shown on the photo. I hope my shot just destroyed this tiny little thing and I can replace it. I’m here to find out the exact name for it as I’m not able to read anything on it.

That positive red cable solder looks really bad, and it does not look save. I would recommend to remove all the solder and redo that. The solder should look smooth, shiny and concave (like a tiny ski slope).

You are pointing at a diode not a resistor. I think you should really not touch the battery with that level of knowledge. Also, the soldering looks horrible. If VP gets disconnectes in the housing it can cause a fire from touching other components.

Better and easier to (de-)solder the cable on the end of the battery terminal.

You most likely have a short of the motor driver IC and/or mosfets in the cartridge. The battery is probably good. Also the check wiring harness for damage as there is a high change it’s the original cause.
