i'm not sure about the punchyness factor... because most packs' surge rating is quite high, so i would think it would not matter. as for your other issues, if you are reading 4.11, 4.1 and 3.9 after a run and the lvc is hitting, you arent getting a full run out of your batteries! If you have a castle ESC, I would not use auto lipo, and set your cutoff manually to around 9.2-9.4 volts. Its safe to keep your lipos from going below 3v per cell, but it isn't damaging until you go to around 2.5v per cell, or drawing lots of amps on low cells. the normal cell you see is probably a cell that is going bad.If I'm right, when you charge and balance, you will see it will start as an abnormally low cell, but then it will reach 4.2v faster than the other cells by alot, which will inrease your charging time too. I had a bad cell in a protek lipo, and my charger would stop after 2 hours of charging, and I would have to restart it to fully charge my batteries. The good news is that lincpimp can take care of you when it comes to lipos.
