I have my LVCs set to cut off at 3.7 to 3.8 v/cell at full throttle. The packs are rarely below 3.6 when I pull them from the aircraft. Its a reasonable storage level.
If I run them down due to charging more packs than needed, I do it at full throttle. That will trigger the LVC by 3.7 v/cell. (and its faster than the lower throttle method)

You need to worry about battery temperature somewhat...
Best current delivery temp for LiPos is 120 to 130 F. You can severely damage the packs if above 140 F. You are reducing the battery life (charge cycles) at 120 F.
When flying in 105 to 110 F ambient air, its hard to keep the packs below 120 F in anything other than a lazy trainer. Get them out and maximize cooling ASAP. (in the shade with good airflow around the packs, you don't really need to use a fan, but it helps)
DO NOT RECHARGE A HOT PACK Let it cool first.
Most modern ESCs have a thermal shutdown where they cut power to the motor if they get too hot. Some of the earlier ones with thermal shutdown also killed the BEC power... There might still be some made today which will do that. There are also still some without any thermal shutdown, so its a good idea to read about your ESC specs.
