Lowest voltage level for Samsung INR18650 25R

Weird, I just got onto this topic a few days ago… posts 772 to 775 here:

I already adjusted my on-time firmwares (s7/) and e-switch firmwares (Ferrero_Rocher/) accordingly, but still need to do my off-time firmwares.

Then again, I don’t want to run my cells down to the lowest possible level. I kind of want the opposite, going down only to like 5% or 10% capacity before recharging them. It looks like a 25R cell has very little charge left below 3.5V or so (resting voltage).
