Does anyone know the function of white and yellow charging cables from ninebot es2 battery??

I think, it is communication line between BMS (battery pack + balancer) and controller.
Battery pack gets commad as such: "eat fast, eat slow, stop eating, I'm not yours battery", and more, eg. ERR21 on dashboard

But my question is: It is any way to bypass this "smart option", and just connect battery pack by thick red and black wires?
