New to RBA, just got IGO-L & have some question....

[moumar81]

I just got Igo-L rba and I drill a bigger hole and did 1 micro coil with 28 kathal about 6-7 wraps at 1ohm. In 4 days, I decided to dry burn it and put in a new cotton and within 2-3 hours, it was hitting weak, i change the battery still hitting weak. The next day I dry burn it and put new cotton and it was hitting fine. It was just weird because there was no gunk in the coil to dry burn. Why did it get weaker? How often do you dry burn or change the coil?

and also I notice the ohm keep on increasing. Day 1 was 1ohm, day 3 was 1.1 ohm and day 4 is 1.2 ohm. Is that normal?

Is it safe to build a dual coil on Igo-L with efest 18350? What is the lowest ohm you can build with 18350 battery on a mech. mod?

Couple of things that I can attribute this to:
1-if you use too much cotton around the coil, the coil can get over saturated and will not vaporize the liquid well or barely at all.
2-the ohm fluctuation will probably be one of two things: tighten the post screws that capture the wires (loose connection), and take a pair of tweezers out and squeeze that coil every time that you dry burn it(between dry burns, not while holding the fire button).

When building a coil, you want either no contact between the coils, or in case of a micro, all the coils touching and making contact all the way around each coil, making it heat up from the center and having a steady resistance reading.

Efest 18350 have a 6.4 amp limit, so .75 is the absolute lowest you can go on it. I don't go any lower than 1ohm on my 18350 for safety and longer vape time.

Forgot to mention, I also use micro coils and cotton in everything except for geni's. I rewick every 2-5 days, depending on the juice and dryburn everytime I'm to rewick. I only recoil when I want to change my resistance, if not, about once a month for that fresh Kanthal action.

I wouldn't dual on a IGO-L, you only have 1 air hole and even if you drill a second, it would be a pain to attach since it is a top wire capture (under the screw heads). The easiest dual coils that I've built have been on a Trident RDA, since it has 3 posts with sloted posts to seat the wires in.

Wandering ohms is almost always a loose connection. Tighten everything down again, if it's still wondering then you probably cut the wire.

Edit- just noticed you're using an igo-l. I'll leave the bit about cutting the wire for anyone else with the same problem on a different atty.

An IGO-W will allow dual coil builds....with post holes to grip the wires....and (IIRC) dual air holes....
Haven't used one myself - yet.....Got one coming from VaporBeast....
Good Luck!
Happy (vaping) Trails!

The igo-w is a 3 post 2 hole Rda. I grabbed one on a whim to try the rebuild thing and it is pretty solid. I put some dual 30g micros in there and it's fantastic at 1 ohm. I want another to build at like 1.3 to use on my vv so I can taste liquids at different power levels and capture the hiding flavors.

I've had that happen to me with my A7
