The german site Akku DB allows you to compare the 2 cells,but always compared to a Pana CGR 18650 so you have to load the site twice,line up the graphs, at the same amps,and flick between the two pages(HKJ,you spoil us :bigsmile: )
I have just ordered 3 Acebeam LG HE2’s from Banggood .I paid the extra for the button top compared to the LG’s flat top.I beleive the E-fest purple 2.5Ah are rewrapped LG HE2’s as well going from the Accu DB graphs.
Calvin seems to confirm the LG/E-fest link and gives a ligue order,at 30amps!Worth reading the whole thread.Good luck.
