California stock, same day USPS shipping Daly BMS assorted sizes

I opened the 12S bms and found the data sheet the IC they used. they always populate all 16S and the IC is capable of 5-16S without any Selection pins. The way to adjust is like this diagram [image] Shorting the extra pins to the highest voltage pin.

according to this and the diagram I think I solder the extra lead (13th) together with the 12th pack’s lead no?
