Thank you agian for the advice!
I tried to tap into to 2 cells of the balance plug but it turns out I do not know as much about electric as I thought I did.
I used this connector in pictured below, connecting ground to ground and the remaining 2 pins to 2 cells of my 6s balance plug. the 2 cells converge into 1 vout wire on the jst plug. When I plugged it in it the pins immediately turned red hot and the middle one melted. What did I do wrong? Thanks!
