Hi vaporeans...I don noe if its the battery issues or somthing i changes thats causing my ego-v4 batt to last damn short....I juz dismantle the head to change the heating wire with a nichrome wire i had laying around(im a rc plane hobbyist,so i cut up foams using nichrome wires alot)I made 4 coils,and fit it back in.After assembling everything,refill and tested...it worked(1St time opening my ego heads..yay!)But after a few press,The battery part will get more warmer than usual and doesnt last long than before i changed the coils.Plzz heelpp...
