3.5minutes is about right for run time on 2 3s batteries getting drawn all the way down to LVC. If you're not timing the run itself, you're going to hit LVC on at least one of the ESC's for sure. I don't think anything is wrong with what you're seeing. Did you measure the voltage of the cells after the run to determin how much capacity was left in them?
sure: at the end of running voltage of any cell is the same: 3.75V... so dropping is over 0.5V under stress...
changing tx timer to 3 minutes i've no lvc hitting!

Keagan-Z06, What motors and props are you using on your set up? Are those OSE speed controls? That thing is fast! Looks like it hadles well with 4 batteries.
I will try and get the video uploaded. I'm using TP4050/2050kv and abc 1815-17-45. ESCs are Seaking 180. I do a high speed run and then a victory lap to cool things off and bring her in. No back to back high speed runs.
The ESC's are wired separately to each motor. Power depends on what your battery configuration is. The throttle lead of each ESC wires into a Y harness that connects to the receiver.
