Is my math correct here?

[bogeyjim]

OK ,

So I want to rebuild my Pro tank 2 to a 1.1ohm nano coil thanks to Rip Trippers video.

Plugging that into the ohm calculator 1.1ohm's and 4V (rough estimate of an 18650 fully charged battery) comes to 3.64 amps.

That's plenty safe for use in a mech mod with an 18650 AW IMR correct?

Or am I way off here? Just trying to play it as safe as I can.

Yep. Good that you're checking. Go ahead and calculate at 4.2V tho. AW IMR 18650 2000mAh is rated for 10A max continuous discharge. The 1600mAh is 24A.

btw; a 1Ω coil will get equal numbers on the Voltage and Amperage. 4.2V will be 4.2A and 3.7V will be 3.7A

Ahh, that makes it easy then

Thanks for the heads up. Also another question for you, would an electronic VV device (MVP 1, and SVD in particular) fire a 1.1ohm coil? Can't seem to find that info anywhere....

Also, how are guys like Rip Tripper using 1.1 ohm coils on things like the Zmax 3 that have an amp shutoff at 4 amps?

He was just vaping on video a 1.1 ohm coil pro tank at 15W on his Zmax v3.

I read somewhere that 1.3 ohms is the lowest you can go on a regulated mod.... if that's true, how was he doing that?

My calculations show at 1.1 ohm's and ~15W the amperage should be 3.72.... However, why is everyone saying lower than 1.3 won't work, when clearly 1.1 is under 4 amps... it's close, but still under...

OK why wouldn't I just buy the AW IMR 18650 1600maH batteries for use in everything?

Seems like a decent all around battery plus PLENTY of headroom for sub ohm vaping....

My coworker had an itaste vv v3 that would fire at .9 ohms. My vamo v3 won't fire below 1.2 evefy mod is a bit diff. I don't know if his was supposed to fire that low or not but he was just llayin around till his nemmy clone arrived. I say find out what your device is advertised to fire at and stay above that regardless if it will fire at lower ohms or not. And nano coils work really well without having to go sub-ohm anyways.

The 2000mah batteries last longer if you don't need the high discharge of the 1600's.

The 2000maH are 5C rated correct?

Yep, and the 2000s sag pretty quick for mech. I found myself pulling them cause they lost their punch and finding they were still at 3.9V. The 1600 kicks right down to ~3.75V. If you're sticking with VV, the 2000s may serve better.


VV devices can have their limitations set by amperage. So a Z-whatever with a 4A limit will certainly fire a 1.1Ω and 3.XXA coil. I think the VAMO, on the other hand, has a resistance limit (but I really don't know), anything under 1.2Ω won't fire. Fancier gizmos, like the Provari, have a triangulated limiter (←I totally made that up). Meaning, X#watts paired with Y#Amperage at Z resistance. So, you can play with the limits on that; but you can't exceed something like x+y or z = limit.

Intresting pd thanks for the input...

Soooo just sticking with the AW IMR 1600 for everyting (Mech and VV) would be a fine choice? Plenty of battery life for me for a day at 1600 plus a ton of headroom for my low ohm mech mod experiments..

This is all sort of mind numbing, but I like it!

Don't want to misrepresent the vape time on a 1600. I was getting 8-10hrs (a day at work + commute); but I vape pretty high nic. and don't chain.

I've been using AW IMR 2000mah 18650's for a while now. Lately I've been venturing deeper and deeper into sub-ohm territory so today I ordered a couple 1600's from RTD. Can't wait to try 'em out on a .3 or .4ohm build.

 

[bogeyjim]

Custom that's exactly what I just did. I picked up two 1600's. Figure if one should die on me mid way through work I'll have a backup. With the 2 1600's I'll have plenty of headroom for some sub-ohm stuff...

Now to order the igo-L to really go off the deep end, LOL!
