I have a Ninebot Max scooter. I replaced the ESC with a VSC. Is the throttle 3.3 or 5v? Is the brake 3.3 or 5v? I have a 13s6p battery. The app is asking me how many amp the batt is. Each cell or total pack? Also, I have a 12 LED light i want to hook up. There is 12v, gnd, and AUX. What is the AUX term for?
