Yep Ive tried changing it via the PC software connected to the USB port and the ESC. Ive tried changing it by using the Hobbywing professional program box connected to the ESC and I just tried it with a Hobbywing program box(old analogue style) connected to the ESC. No matter what I do I cant get it to * the setting Im after. Trying to set the battery to S4 instead of auto detect and have been pressing the ok button each time.
