Hitting the chemical limits of the batteries is what causes 1/ rapid aging and 2/ catastrophic cell damage and/or short failure and runaway, so if what you say is true (I don’t think it is) then the other manufacturers have implemented poor state of function control (SOF) and it would be a good idea to avoid. Proper SOF control is loosely required for ECE R100 which most manufacturers would have, but OTOH I am convinced that it’s possible to fudge that certification. Source: battery controls engineer.
