Is my Flux Lipo cutoff working or not?

I just got done with my first long bash session with my Savage Flux and damn, these batteries were empty!

I'm pretty dang sure I had the Auto lipo off cause just all of a sudden the car just basically stopped running cept for a few short bursts of power so I went ahead it shut it off as I figured that was the end of them. Was that caused by the ESC cutting the power randomly because the voltage was low or something else?

But after looking at the amount of mAh put back in the battery, I'm wondering if the Autolipo is on. I went ahead and went through the entire programming procedure with the transmitter and said "YES" to Auto lipo but now im worried...
