The HE2 is the same battery as the purple e fest 2500 mah 35amp batteries. I went looking for batteries today and one shop had fake Sony vtc 4 batteries for $11.99. I saw those and laughed, i bought a 2 bay nitecore digital charger and left. I did buy 2 e fest purple 2500 mah batteries from a different shop but they are still charging
I plan on using them on a hcigar penny mod clone with a hcigar darkhorse rda clone with a dual coil .31 ohm build. At 4 volts that should give me 51 watts and that should be more then enough for me
I can't imagine using a .2 ohm build that has to be about 80 watts
From what I've seen online Sony doesn't even make those batteries anymore and it's almost impossible to find real Sony batteries online. Someone on here posted something saying xtar i think is the same thing as the Sony just under a different name but i cannot remember the place he said to get them from
