I understand, but 300A peak can be reached also with Panasonic NCR20700B15A or NCR20700A30A cells, with NCA chemistry,colder due to aluminum oxide, and a longer lifespan.
LG HG2 can discharge the only 12A-13A before achieving 75 degrees and goes cut off. So 20A continuous discharge is a warming fantasy.
Sony VTC6 claim 30A continuous discharge rate, but achieve 80 degrees and cut off because become extremely hot. So work well on 15A-18A discharge rate. Heat for battery cells means also a short lifespan!
