Well, you are using un-protected batts as well. Keep making lower ohm builds and just tapping the button to see if it goes red (cutoff kicking in) or green/yellow (firing).

Hi I've just test fired it about 5 times at 4.5v which at 0.9ohms is 22.5Watts and 5 amp draw and it works but tastes horrible
And whilst typing just bumped it up to 5 volts which at 0.9ohms is 27.7Watts and 5.55amps draw????
Whats going on? pressed button for 3 seconds as well (not just short pulses) - maybe its down to the battery, its not getting hot.....

Yeah I can fire a .9 ohm coil on my Provari too, but can only take it up to like 12 watts because of the amp limit on the switch. You can fire a .9 ohm coil on a 15 watt device but it gets fussy, if you get into higher watts then one is better off with a 1.5 ohm build or higher. Uses less amps and can max it out.

the Provari has a mechanical switch to drive the circuit board??? If thats the limiting factor, then a better switch is the way to go....

Think you'll find this is down to the battery used as I don't own a SVD but can get a kick clone to fire lower than 1.3ohm down to 1ohm and when trying to work this out switched batteries to lower A and it wouldn't fire "sometimes", also think down to charge on battery but can't find no exact specifics why.

sounds like the kicks measure amp draw as they supply voltage, when the amps become low enuf ( due to low voltage, low ohms) the kick shuts down... explains why the low amp batteries "turn off" when used in low ohm applications

My SVD will fire a 0.9 ohm coil as well. Could be, however, that it downs the voltage in order to maintain the 15w/5 amps limit. In that case the device won't actually be firing any higher than 3.7v even if you have it set to 5v. I don't have the equipment to test that though.

EDIT: just did a subjective test. 1.05 ohm kayfun on the SVD. Fired at 4v, which is about 15w, then fired at 5 and 6v and I didn't notice any difference in vapour production or taste (no burnt taste). At 3.5v there's a difference. Subjective, but I'm quite convinced that the SVD is limiting the voltage in order to not exceed 15w.

Hi Kris
That's good to hear, not just mine then, do you have any suggestions on mech mods, there's that many about i don't know which one to pick. I'm more a fan of good engineering than looks, so something with a low internal resistance and good build quality is what i'm after in 18650 size then i'm not messing with different batteries and they seem to be the biggest capacity.
PS the SVD is good but mine occasionally doesnt fire if i'm not pressing the button correctly and its starting to get annoying (i would get a provari but its too expensive for me)

I thought it was just my svd lol. If I double hit (which I always do to do anything in cigarette like lol) but seems on the second hit if I don't push it exactly right and directly down in the middle it doesn't fire at all and I know it's not cuz I reached the ten second mark. I always let go of the button in between double vapes and never seen it flashing when this happens. Weird. Lol

Thanks for the recommends, the vanilla looks great.... just wish they had on in stock somewhere, the US and the cloud9 uk re-seller webstores has no stock and 'local vape' only has super expensive customised engraved ones. I will have a look at getting the Nemesis clone from HCigar in the meantime and i've saved a search on ebay for the vanilla, you never know one might come up.

By the way try like mount baker vapor. They have the k100 and k100 + I believe. For like 32.99 US dollars? After shipping ($6us) and my 11% off coupon I paid maybe 32.96. It's my first mech after mvp2 than svd and too many cartos and clearos. Lol. I have an igo-l and after a few weeks and mastering coils I pulled the trigger today actually and bought the k100+ to get comfy with mechs. If I keep reading I bet you got one as this is probably a really old post eh lol

Anyways since I'm waiting on my first mech lol. What's the lowest ohm the svd or mvp can read. I am not trying to fire sub ohm coils on it lmao but use it as an ohm reader. I want to try a one ohm to start but knowing me I'll get lower just to say hey I tried that. Unfortunately my svd and mvp2 are what I have for an ohm checker for another few weeks

Hi Dan,
The absolute lowest ohm build my svd has read was 0.7ohms and it only fired that occasionally (which was amazing really as its only supposed to fire down to 1.3ohms or thereabouts).
I have now got many mods that i use:
VV/VW devices - SVD (still going strong), VTR, MVP, MVP2 and about 5 kamry kicks for use in some of my mech mods.
Mech Mods - SS Panzer by MCV, 2x SS Panzer clones by Fasttech, Vanilla, Copper Nemesis, SS Nemesis, SS King, Brass Chi You, Maraxus, Hades (26650 mod), Private V2 Copper/Brass/SS mod by Grand Vapor (18350 mode), The Hammer (18350 mode)
RDA's - Atomic by MCV x2, IGo-w, IGo-w3, Trident, Helio Foggy, Fatty V3,
RBA's - Ithaka, Kayfun 3.1ES, Russian 91%, Rocket v2, Fogger v3, AGA T2
Other atomisers - About 10 iclears (various), protanks 1,2&3's

Don't be too scared of building low resistance coils, i vape all day mainly on my Panzer/Atomic using dual dragon coils and cotton at 0.26ohms. I only use Sony VTC4/5 batteries (30amp continuous) to be as safe as possible. As long as you check your builds now and then after they're built visually and on an ohms checker you should be ok. I have found that low resistance builds vape far better for me and if i build say the ithaka or kayfun at 1.5ohms or above i just put a kick in to help give them the extra vapour production i prefer. Good luck with your builds and i have found by experience that if you keep trying different builds on any atomiser, eventually you will find a build that suits that particular type of atomiser regardless of what reviews say.

regards:)

I'm more of a flavor chaser than cloud chaser. But kinda want to try sub ohms lol at least once. Just no ohm checker but my svd and mvp2 will check lol. I think my efest 18650s 1600mah can handle no less than .5? Ohms if I remember correctly. Or is this right. Actually I think .3 not too sure. It's an 18650 efest flat top from my baker vapor lol I think it'll handle that low

I'm not sure what amp rating your batteries are, the efest 18650 2000mah ones are 10amp.

Its quite simple to work out -
Assume batterys fully charged at 4.2v.
4.2v x 4.2v / resistance of your build say 0.5ohms = 35.28watts
to get amps divide the watts by the voltage so 35.28/4.2 = 8.4amps
If your batteries are 10amps this should be ok - depends on how much 'safety factor' you want.
If you build a 0.3ohm coil(s) then 4.2x4.2/0.3=58.8/4.2=14amps (way over the 10amp limit so unsafe) but if your batteries are 20-30amp if would be safe to vape.

My current build in my atomic is 0.26ohms so
4.2v x 4.2v / 0.26 = 67.85watts / 4.2 = 16.15amps - i use 30amp batteries so i have a saftey factor of just under 50%
I have built a 0.15ohm build @ 28amp draw (just to try) but i felt i was pushing my luck so i stick with my tried and tested dragon coil setup 7-8 coils of 2xtwisted 0.32mm kanthal wires built using a paperclip and cotton wicks.

I must admit some builds produce less flavour the lower you go but the atomic with dragon coils as above is fantastic on flavour even using 100% vg juice and tons of vapour (i don't use it in public because it draws too much attention lol)
