How much can we improve?

[Johnny2puffs]

Why do you think a car has so many relays?
A relay for every dam thing. All those things on your steering wheel like flickers, low, dim, wipers all activate relays. You can hear them, especially the flickers.
It is because the switch that you activate cannot take the amps that a relay can. So you activate a low amp switch that in turn activates a high amp relay to turn on the lights etc. This is to protect those small switches.
I am quite surprised that my Leo bat button can handle 2.5amps without a relay. How long it will last at this amperage??
A relay is far too big to fit into a e-cig for those guys that want 4 amps at 6v. Never mind the circuit needed for that.
Forget about the main board guys stating that they use their 6v Provari's and other stuff with 1.5ohm atty's with success.
They are fooling themselves as the bat will not allow that. Just too high amps for the switch and for the bat internal resistance. It will either not activate or will be restricted by the circuits 2.5amps max allowed as protection.
So just be happy with your 3.7V bat. This is as good as it gets.

As long as it's a quality switch you shouldn't have any issues. I've never had a switch issue on any mod. Anything electronic can fail but it's far from the norm.

No one's ever said they use a 1.5 atty at 6v on a Provari, you can't. It has over current protection, won't fire and will give you an error message until the issue is corrected.

I'm glad you're happy with 3.7 but to many people including me it's not as good as it gets. Variable volt, being able to adjust the vape to my taste and not worry about matching ohms to the battery with it being regulated to that voltage and no drop off as the battery drains is where I want to be.

I think we can improve a lot. It's amazing the strides I've seen in equipment 16 months I've been vaping and I have no reason to think that won't continue with the growing popularity.

Yes, it is getting more popular. But 2.5A is max. for the hardware. A push to 3A is bad for the button and coil. Never mind the liquid burning and the taste!!! above this.
The optimized amps is 2.5.
I have been in this profession for 28 years. I know what I am talking about. Unless you want to carry a car bat with you and puff on a bicycle pump then yes. Go for it.

No one's ever said they use a 1.5 atty at 6v on a Provari, ???

I read a post here on this forum where a guy insists he is happy with his Provari at 6v on 1.5ohm. He does not know that he is being cheated by the 2.5amp cutoff.

What Nomoreash said.....When I first got my Lavatube and tried a LR cartomizer on it, I did say to myself, "what a waste".
Then it hit me.....LR stuff doesnt work on VV's......neither does dual coil stuff that great......But....you cannot beat the VV for a steady, regulated vape even with LR stuff.....Its nice to have pretty much the same vape "hit" all the way through the battery life as opposed to unregulated stuff...YMMV

High amp switches have been around long before vaping was and are reliable if it's a quality switch.

Liquid won't burn if you raise the ohms along with the voltage. I have no burn with my mod adjusted to 4.9v with a 3ohm atty nor do I with it adjusted 3.7v with 1.7ohm atty. Both are just over 8 watts which = heat. The higher voltage/ohm combination pulls less current which = less stress on the batteries and equipment.

Size is really more design factor. I've got vv mods that use smaller batteries 16340, 14500 and larger mods that use 18650 batteries, difference being vape time in between charges, voltage range and performance is the same. The larger mod is 4.5" tall, no where near a car battery.

If you could provide the link to that 1.5ohm at 6v Provari post I'd like to see it. This is direct from the Provape website:

"Amperage Limiting to 2.5 amps
The ProVari will monitor and shut itself off if it detects any excessive over-current conditions.

If this error occurs the ProVari will alert you by displaying E2 on the digital display.
Fix: Lower your voltage setting."

6v at 1.5 ohms would be pulling 4 amps. Aside from the fact the Provari won't let that happen I'd like to ask him WHY he would want to. Juice would be burning if his atty didn't pop first, that's 24 watts.

If somebody did want a mod with higher current capability they are out there but it won't be a mod with a booster circuit that gets it's power from a single battery which is fine for most people.

when i bought the madvapes 5 ml tank it came with a 1.6ohm smoktech carto as soon as i put it on my provari at 4.5 i hit the button and i got an error...I had to get the 2ohm cartos for the tank to use it at 5volts...it reads 2.1 ohms and has been working great at 5 volts ...so far anyway...

I've been using a smoktech 1.7 carto at 4v on my lavatube with no problem. with the voltmeter attached it shows the voltage underload at around 3.9. I like the smoktech cartos, they seem to wick better and are easier to punch myself. I just keep the voltage on the low end.

Nomo,

I am talking about a tiny switch. What in your thoughts is high amps? 2.5A or 4A in a tiny switch?
I fully agree with the rest of your post.
Been trying to find that thread again but can't. It is a very long one mostly about Spain and a new model.

While I understand what you are saying (it's what I did for a living) you would be amazed by what can be done with electronics.
If that 2.5amp limit just doesn't do it for you, try a OKR-T/6-W12-C switching converter (digikey.com).
Here is you a wiring diagram (thank you Mamu)

I now have that (less voltage meter) in a 3xAA battery box.

Personally I prefer a larger switch, has nothing to do with reliability, just preference. Mofsets have been used for a long time to limit the current to a smaller switch if the need or design calls for it and are reliable. You can check the moders forum for more info and implementation.

I see little to no need for as high of amps as you keep coming back to. It's easy to hit 5 volts or more with much less current draw than you keep referring to and if you want a mod capable of those amps they can be made very easily. 6 and 10 amp switching regulators are cheap, easy to find and you can just about find step by step build threads on them, wither you want a large switch or a smaller tactile switch with a mofset.

relays were not needed 30plus years ago...just somebody behind a desk complicating things so the average joe can't fix his own car,,,plain and simple

A common misconception with specifications is that a switch is rated @ 2.5 amps. So I cant use it with anything higher. What you don't see in the specifications is that the reason why it's rated this way, there are 2 reasons that are most common and they are heat and conductor size. If your not holding the button down for extended periods of time, a quality switch rated @ 2.5 that has a large enough conductor to support higher amps will last forever. If it's due to conductor size, what you wont see is that your actually not running 3amps through your circuit, it's really only 2.5. Check it with a meter and see how many amps your drawing from the battery. Or you could use an LED rated @ 3amps as a load light.
