Lowest Ohm Coil Possible On Ego-Style Battery

So, I've read a lot of things saying that ego-type batteries don't do well with LR atomizers, that they'll work for a while but sooner or later the circuitry will fail from not being able to handle the amp draw. But I haven't been able to find any detailed specs or information on exactly what the max amp draw is... I'm currently using a 1000mah VaporZone Pro Variable battery, which as far as I can tell is just a re-branded Kanger EVOD VV, with a rebuilt 1.8 ohm nano coil (14/15 wraps 28 gauge) in a PT2 Mini v2, vaping at 4.4v/10.76W for an amp draw of 2.45. I was using a 1.3 ohm nano coil (11/12 wraps 28 gauge) build, but while using my backup battery -- a 650mah VaporZone Pro (which appears to be a re-branded Kanger EVOD pass-through) -- I tripped the protection, which means it doesn't fire until I plug it in into the standard screw-on 510 charger. Initially, I had forgotten about the protection feature and just thought it was dead because the only mention of the protection feature, and how to reset it, was on a little paper that came with the kit I first got. Even there, it only described it as over-charge protection, not an over-discharge protection. But I put it on the charger for a sec, took it off, and it started firing again. Now, though if I put anything less than 2.2 ohms on it (i.e. 1.8, which it is rated to handle), it fires once then trips the protection and I have to repeat the resetting process -- which is annoying since I only use it when the VV battery is charging. Since that I haven't gone lower 1.8 ohms; I've only been vaping a month and these are my only two batteries, so I can't really risk losing them. I guess what I'm really asking is: how low can I build my coils on the 1000mah VV battery without dooming it to a premature death? I know similar questions have been asked before, even on this forum, but battery technology -- especially with regards to vaping -- evolves quickly. So, what may have been true even a year ago, might not be true now. Also, all the material I've seen on this subject uses authentic Ego's as the benchmark, and the above mentioned Kanger batteries seem to be of a higher quality with more robust circuitry than their Ego counterparts -- so the same limitations need not necessarily apply. Even though the vendor's site where I purchased mine lists the lowest compatible resistance as 1.8, I think that's just a reflection of the commercially available stock atomizer heads and not an absolute limitation of the battery. Anyways, I know this was a really long-winded and technical question for my first post, but it's the only question in my admittedly short vaping career I haven't been able to find a satisfactory answer to through lurking here and google-ing.

Running loooooooong paragraph. Didn't read it. Sorry.

Answer to your question on title .. Look here.

Thanks for the replies... I guess I'll just play it safe for now and stick to the 1.8 ohm coil... I really like my 1.3 ohm build though, it had this great sizzle to it. I was running it at 4v/12.3W briefly, but that's a 3.1A draw and I didn't feel like pushing my luck for too long. Unless somebody has used coils <1.8 long-term on a comparable device successfully, I'll just wait 'til I get a mech to go crazy with my coil building.

My supplier mistakenly sent me 1.5 replacement heads for my iClear 16's, running on iTaste VV. Rather than go thru the hassle of replacing them I tried them out. Actually, they seem fine. I run them up to 8 watts with no problems, and battery life doesn't seem affected. I know they're probably placing a little more drain on the bat, and I don't like them too much because they tend to run hotter (at least that's my perception) and there is less flexibility. But so far, no real problems.

I messed up when I made the title to this thread, my concern is more about maximum continuous discharge amperage than the actual ohms of the coil.

According to another thread on this forum the Ego-C twists have a 3 amp limit. (I'd post a link but I'm not allowed.)

So to run the full range of an Ego-C twist (3.2v - 4.8v) you couldn't go below 1.6 ohms... 4.8v -> 1.6 ohms = 14.4W, 3A

That thread was from 2012 and I think the EVOD VV is newer than the Ego-C twist so it can probably handle as much... Hopefully...
