How much can the voltage range of Lithium-Ion cells be stretched?

A more nuanced answer than you received so far is that 4.27 V is not a significant problem as long as the charger is turned off (disconnected) after the cell is full. Then, the cell voltage will relax down to a safer value. Compared to charging to 4.2 V, the advantage of a higher charging voltage is that it stores a tiny bit more energy in the ...

What a minimum voltage for 18650s? : r/batteries

I''ve heard it''s risky to go below 2.8v and I think that''s the cutoff point of a lot of protected cells. For testing capacity, use the data sheet minimum, and a C-rate below 0.1C (10 hours). The reco to stay above 3V is only for normal cycling, to get extended longevity. 3.4+ even better. 18650 is Just a form factor.
