Could you confirm the pin out? With my multimeter im getting N9 continuity to the negative terminal on the battery.

On the photo above is marked as Vss. Dont want to connect them the wring way haha. Thanks

@Rocker7837 It is correct that VSS (which means usually means ground) is tied to battery pack ground. The whole BMS board uses that as the ground reference. You can see that in the schematic if you'd like. In short, that pinout is correct.

The pinout order is exactly the same as pictured for the V7, the GND pin is just moved in to the same group instead of being slightly separated from the other pins.

Hello, Does anyone have an original firmware for the SV10, unfortunately I deleted mine. Thanks

I don't think the original Dyson firmware is publicly available. It is read protected on the microcontroller so you can't just read the firmware without bypassing the read protection somehow, which I don't know how to do.
