I just have a couple of questions before wiring up my 12S4P Battery to my BMS.
So this is the BMS I’m using from Batterysupports.com
So from the diagram.
I know I have to connect my Negative wire from the end of my pack to the B- on the BMS I have to connect the negative lead from the charge port to the P-.
So then I’m left with the positive wire, that goes to the anti spark.
My question is do I run a negative lead from P- to the antispark as well?
And N- remains unused?
