Okay, the battery you've got is just barely has enough amps. Until you get a bigger Battery (18500 or 18650) I would wait till you get that ohm meter.
I just ordered my first mech mod and have just done a crap ton of research on stuff in relation to unprotected mechs. You want to get a battery with at least 10 amps continuous discharge (max discharge is not this) and at least 15C. If you know what ohms the coils is use a ohm calculator online. It will tell you how many amps you are using. A 18350 with 6 to 6.4 (I have the efest you have and a AW that size) is barely enough to be safe. Some say you should have 50% more amps then what u are using. If my max is 7 or 8 amps and I am sure it will go no higher I try to have at minimum 10 amps but that is is still cutting it close. 1 ohm with 6.4 should be safe but I have found that coils can fluctuate after using them or if you adjust them in any way. It is just safer to get a higher amp so you don't have to worry.
I didn't mean to sound hard on you. I just want you to have a good experience.
With the ohm meter I would get some 29 or 30 kanthil and a few different wicks. If you want to use cotton I found a organic seller that sells it raw with no pesticides. You either have to boil or soak in alcohol. There is also this site with a ceramic wick that is flexible that they take the time to pretreat it in a kiln. If u gotta use a silica get a verifiable ekowool dealer, Alot of people here order from
fastech (china), I don't. The shipping is slow and sometimes you get total crap. Do not buy wick and wire from anyone that doesn't verify where it was made. You are inhaling this stuff so know where its coming from. There are cheap sellers of stuff in the states so you do not have to do china. If you are interested I will put the best together in a list and message them to you.
Now if i was using 26 kanthil I would do at least 10 to 15 micro coils. Get a small screwdriver (size of on in a glasses repair kit) or a 1/32, 3/64 or 1/16 drill bit. Less cotton is better. Keep it fluffy and just twist one end to thread the coil. Drip your
juice all over the wick and let it sit.
Try
vaping it. If it still sucks, add more wraps to the coil. Forget about 1 ohm for now. keep rebuilding the coil till it works. Without control over volts and watts you have to do it the hard way. Just do not go lower than what you have established as 1 ohm. The 6.4 amps might not stand up to the fluctuations.
