Could someone please answer a question, on the RX8 Gen 2, when you choose you LV cutoff, you can choose a specific number, i.e. 3.4v for a 3s pack

Is this number per cell or pack voltage, like should it be 10.2v instead of 3.4v for my 3s pack?

I have it a 3.4v right now, but LOL I definitely don't want to take my whole pack to 3.4v
