Firing a coil below the recommended ohms

So I was building a coil trying to get it at .3ohms of even higher(my eleaf ijust 2 is not supposed to go below .3 ohms) and I was building the coil on an rda on the ijust 2 battery. I do this because it is a much better grip as opposed to just holding the rda. Well as I finished placing the coil within the rda's posts, I accidentally hit the fire button. It was very quick probably not even enough to ramp up the coil. But I checked the ohms on the coil after and it came out to .25 ohms. Now is that an issue? Is my battery now dangerous? Im just trying to be as cautious as I can and it was a mistake on my part to accidentally fire it without checking the ohms first. But I've heard of situations where people's mods explode and I'm trying to do whatever I can to prevent that.

If you want to be safe you should check the resistance on a meter.

I'd also suggest adjusting the coil to see if you can get it back to the .3ohm's. I you checked the build on steamEngine and it's supposed to come out at .3ohm, try squeezing the coil gently with a ceramic tweeser, or brushing a screw driver acorss the coils.

If the coil doesn't come back to .3ohms, then the choice to fire it or build a new one is yours.

Personally I wouldn't fire a coil at lower ohms than a device says it can handle.

I'm actually surprised you device will fire lower then it's published limit.

Thanks for the response. And I actually was just testing out some new wire so I tried to make a quick coil but as soon as I saw that it was below .3 ohms I threw it away because that is under the allowed ohms for the ijust 2 battery. Tbh I'm not even sure it fired I just hit the button. But my concern is primarily the safety of whether the battery is still ok to use? I'm new to building and I have alot to learn but Im hoping it isn't a huge hazard that I accidentally fired at below the appropriate ohms. I mean I am really not sure how serious it is, I've heard of how dangerous it can be to fire below the limit such as batteries exploding. But I certainly won't do it again.

I think my real question is, am I overreacting a bit? I honestly have nothing to base my knowledge off of firing below the ohm limit because I haven't done it before and I've really not heard that much about it. All I've heard is that it is extremely dangerous and I'm trying to get an idea of how dangerous it is and whether my situation constitutes as being a hazard or if it is not that big of a deal. Plus I do not think the iJust 2 battery has too many safety features. It is basically a mech mod

Are you sure it was .3 ohms to begin with? You said you tested it after you hit the fire button. I don't think it should be a problem, though. You mentioned you barely fired it, and the ijust 2 does have some safety features to it. Short-circuit protection is among them.
It was not .3 to begin with. I had no idea what it was. I was just using 24g and I was making smaller wraps to making a lower ohms build but no lower then .3 but it came out to .25. And I read it on the ohm meter after I hit the fire button

I wonder if it does like the rest of eleaf stuff. Most just won't fire if ohms are too low. I had an istick a while back, if the ohms were too low it would just blink and not do anything, my DNA did the same thing but said check atomizer.

I was just thinking the same thing. Regulated mods that have a minimum resistance limit simply won't fire the coil if the resistance is too low. The only specs I could find seem to indicate it can power down to .3 with kanthal and .15 in nickel. I doubt it will fire below those tolerances

IMO you have nothing at all to worry about Younghorsejr. The ijust 2 is not recommended for use below 0.3 ohms but the short protection cuts in at 0.2 ohms. You can buy 0.3 ohms heads and they have a resistance tolerance, meaning some will be a bit less and some will a bit higher than 0.3 ohms. Have a look at the Rip Trippers review on the vapordna.com webpage and he says he was able to run a 0.2 ohm build on it.
