see here for link on rebuilding heads/ wicks.
Its entirely up to yourself. The more wraps the bigger the ohm's. For a standard ego battery 3 or 4 wraps will be fine but if you have a VV device then you can add more wraps. I usually wrap mine about 7 or 8 times using my methodThanks for the replys
Managed to get some I got 1m of 2mm for 2quid and free postage so il try 2 wicks.
I know this is a how longs a piece of string question butt....
Ballpark figure, how many wraps should I do with .2 wire on 2x2mm wicks on the ce5 head
Please remember to check your work after you finish with a multi-meter, or you can kill your eGo battery whit77
