LVC setting question

[Ozric]

Hi all
Not been running electric and brushless very long.
Just like to get an idea from some more experienced users as to what low voltage cutoff people are running.
I did some reading and see that quite a few set it higher to extend life of the cells etc. So I set mine to 3.3v.
I know when under load the voltage will droop, but whn I put my packs on charge after depletion, all cells are at 3.58v, seems consistant across both of the packs I am using, which are 4500mah 30c turnigy packs.
When I charge them they both seem to take 4200mah to top up.
So will I be safe to lower the LVC to get a little more run time?
Has anyone had any probs leaving the LVC on its default 3v?
Thanks in advance
Jon
