what lvc do you guys use with 2-5s lipo in parallel

That sounds like a setting for nimhs, so it would indeed be too low for lipos probably. Take a look at this thing:

In theory though, you could use a 4s lvc/ battery monitor that plugs into the balance taps on the lipo, and monitor the voltage of 4 out of 5 cells. When the voltage of those 5 cells drops below 12.8v (3.2v per cell) for example, then you know it would be time to stop running:
