Hey nialz if your running low res you'd get a lot better performance and power output with stacked 18350's. The 3000 mahs will likely not work out for you. As most of them have 6 amp work load rating, not even enough to run it proper. The zmax spikes to up to 8 amps from the battery to run the boost circuit fully loaded. The v3 has about a 2.5 amp limit with one 18650 as far as I can tell. To get to 4 amps you need stacked 350s.

With 1.5 ohm coil your maxing out the circuitry at 3.8v & 2.5amps getting 9.8w and running the battery down fast. If you run stacked 350s with 1.5ohm @10w you'd only be running at 62% capacity. Providing longer battery life and won't hit the amp limit till 6v.

I'm a heavy vaper as well and if I run a 1.5 - 1.7 ohm, a 650 efest 2000 lasts only 4-5 hrs, if I run a 2.5 ohm I actually get more power (14.5w) and the battery lasts 8-10 hrs. I can get 12watts @ 6v out of a 3 ohm only pulling 2 amps (2 more watts than 1.5oHm)and it lasts 12 hours.

The optimum ohms for 1 battery is 2.4ohms providing 6v 15w @ 2.5 amps

Edit - * the MVP has a 3 amp limit

Yeah it seems no one really talks about this fact at all. In my over year on here I never saw much, if any talk, about it. I have mentioned it to others including provari owners and all I get is crickets in return. I think this lack of understanding is a reason many go to mechs with lores. Still stuck with changing bats after 4 hrs. Sure this doesn't mean as much for an 8watt vaper, but they could still double their battery life with higher ohms @less amp draw to provide the same wattage. Spread the word guys this applies to all vv devices. Only the new v2 provari can put out 3.5 amps with one 18650 but is limited to 14.5w. MVP has 3 amp limit but I hear is limited to 11w? Can be confusing.

I'm running a 3 ohm Vcore, vertical hollow core micro coil, of 32 right now and it works great. Heats up instantly compared to a 1.7ohm of 28.

I know I've posted this a lot but here is the chart to help you figure your optimum coil res for your vaping style. Amp limit is your primary figure. https://docs.google.com/spreadsheet...xZLVd5aDkwUEJEZXc&f=true&noheader=false&gid=1

Yes lower amp drain for the desired wattage , the battery will last longer, with the same wattage output. So for your calculation figure your true watt range that you vape at. Go as high in ohms as you can and still get that range. To maximize battery life.

The amps are for max power, amp load calculations, watts are for equal power calculations. Volts can be thought of an end product setting(means to an end) to equal the others, or for backwards calculations.

Although it's not as big a deal since you use pretty low power as is but you can maximize the battery life. Possibly 25% longer with a similar vape at the same overall wattage. Based on what you've said I'm guessing 2 ohm at 3.7v & ~7 watts not really an issue unless you run single 350s then it could help you out a bit get another hour out of a battery maybe

** This is a bigger deal for those trying to run higher power like myself. Regularly running at 15 watts, or using lo w res coils. **

Funny jd I actually get great performance from a 3 ohm vertical micro. Heats really fast on a vv. I only have 32 to work with. The 1.7 or so take too long to heat up because there's so much wire. I always run at 15 watts/6v also.

It seems there is a dead zone between high ohms 32 heating really fast and hot. And sub ohms heating really fast. Res between just doesn't pull enough for the mass of wire to heat fast till you get low.

This is a vertical 3 ohm 32 g dry burn @ I think 5 v after about 2 seconds. Gets really hot really fast. It is literally that bright it nearly blinds you.

I don't think you get this kind of bright heat till you get SLR? At least not in my experience.

Once again showing the dead zone on heat up time. 1.2 on a vari and .5 on a mech are 2 totally different things. Also 1.2 on provari you are lacking power even version 2 with 3.5 amp output. 1.2 @ 3.5 amps = 4.2v 14.7 watts.

.5 @ 4.2v = 8.5 amps, 35w
1.4 on new provari 3.5 amp = max out put 4.9 v at 17w
1.4 on older 2.5 amp provari or any standard vv pv (4-5 amps only possible with stacked 350's)
Maxes out with 1.4 ohm at 3.5v 2.5 amps and 8.75w

As you can see low res can be detrimental to performance on a vv.

To get optimol performance you just need to calculate. For a 2.5 limit a 2.4 ohm coil @ 6v for 15w that will give you maximum power output. If you go lower resistance than you amp limit can handle at 6v you lose power/wattage to the coil. For a 3.5 amp limit a 1.7 ohm would give you the maximum performance @ 6v & 21w.

To figure you optimol coil res to amp limit simply look at this chart and correspond you max amp limit to the res at 6v. Good to 1.4 - https://docs.google.com/spreadsheet...xZLVd5aDkwUEJEZXc&f=true&noheader=false&gid=1

For below 1.4 use the calculator here - Ohm's Law Calculator
Put in your amp limit and 6v ..... 3.5amps 6v = 1.7ohms that is the true limit on new provari 2.5. Giving you highest power output it can handle.

Yeah.. But in general for most vv apv's this rule of thumb works. A twisted 32 or parallel 32 is still about the equivalence of a single strand of 28. And yes ofcourse the length of the coil if over 10-12 will increase heat up time.

But still without even seeing that provap doc, my calculation was correct for max output = 1.2 @ 3.5 amps = 4.2v 14.7 watts. ... Its too bad they don't allow full 3.5 amp power. I'm not completely sure if others like the zmax limit at wattage or volts, iow

Basically I'm trying to make a point on heat up time. You can get that Fast heat up from either high ohm on a vv or sub ohm on a mech anything In between seems to lag.
