I just ordered two (waiting on delivery), 2-cell 7500mah 90c Ultimate Nano-techs and just stumbled on this post. After reading this I will be monitoring both batteries like a hawk for the first 10 cycles once they arrive. I run two Hobbywing SCT-Pro v3.1 ESC in a Losi SCTE & SCTE/Pro8 buggy conversion and from what I've read on here people recommend running the HW SCT-Pro ESC LVC @ 2.8v per cell due to overly sensitive voltage sensors.

I am now second guessing running at that 2.8 LVC setting, I was apprehensive to go that low to begin with but at the 3.2v LVC setting I was experiencing the early LVC kicking in due to voltage sag under load (550 2-pole motor). In fairness I was running inexpensive 2-cell 50c 6000mah Zippys, so they could be a factor. I'll report my findings in a couple of weeks once I get some cycles on the new 7500mah Ultimate 90c Nano-techs.
