Can LiFePO4 Batteries Combust in Thermal Runaway Event?

Not trying to be a dick, but a LOT of "dumb" BMS have their cut-off set to 3.75V. Do we all remember when the EG4 were 3.9V????

EDIT: :p (smiley added)
True, but some of the earlier cells were tested to those levels. Sinopoly, CALB, Winston come to mind... then they got wise and lowered the numbers. less issues for their cells. now we have bargain basement makers pumping out cells and they cannot even be safely charged to 3.65 more than once or twice a year for balancing purposes.... that and red handed thieves who sell rebadged used units from chineese bus's as new grade "A" EV levels cells...
 

Ah, yeah, Winston cells. I thought specifically about blue prismatics and had my tunnel vision enabled.
