I was cautioned today, any merit to it?

[rufus1138]

I'm running currently a dovpo e-mech topped with a stainless patriot rda running a dual micro coil build at .5 ohms in 26 gauge kanthal of 10 wraps each, vapes like a beast at 6 volts killer flavor and huge density, I was told that this is dangerous to run big wire with a high wrap count, the coils have performed flawlessly for over a week now, no significant discoloration yet, no signs of hot spots and frankly they look gorgeous and very symmetrical, I was told this is a huge risk to "blow my chip" or "melt the e-mech in my hands", truth or fiction?

 

[tmassey]

, I was told that this is dangerous to run big wire with a high wrap count

i dont know too much about your particular mod or batteries so if you go too low in resistance you could run into problems, but it wouldnt be because you were running too many wraps, thats just ridiculous

 

[rufus1138]

they're efest 30 amp imr 18650's, i did the calculations and im only pulling 12 amps when i burn this rig at 6v. works out to 74 watts or so but still, its in the safety range for this chip and i dont see the idea that this will "put more wear on the chip" a pcb is non mechanical, i work with them all the time in the aviation industry and the only point of failure we have is the mechanical relays they put on the pcb's that when they short or fail in the right way they can fry a few traces but otherwise the boards last for 20 years or more. oh well, any opinions on my coils? i feel like they're pretty killer.

Great setup classwife, I think your only worry is the unknown..... what chemicals are we inhaling and can they be dangerous down the road? Do these chemicals change composition at x degrees and THEN become dangerous? Is it really safer than traditional cigarettes? All questions that can only be answered in time.

You'll wear out batteries faster and go thru more juice, but who cares?? Looks like a great vape to me.

The thing is, that 12A is not on the battery, it's on the switch in the regulator. The 30w limitation on the VW, and some things I've seen from dovpo engineers, make me wonder if the switch in there is a 12A capable switch. If it's not, then you are risking damage to the chip to run it that hot.

Are you getting a measured 6v out to the .5 load?

 

[xxvcrfuneralxx]

everzon states that the e-mech has a 7 amp limit not specifying that the chip won't allow more than 7 amps or that it can only handle 7 amps. asked company directly if they ever get back to me i'll update

 

[ukeman]

Yeah, the specs say its up to 30w, so running 6v at .4 or .5 ohms is about doubling the wattage ... and one of the youtube vids shows thats how the guy is vaping it.

I don't get it... ?

what i like is that the chip gets good reviews, AND it has double 18650's ... love that.

I got one to try as another "backup" but was planning on staying around 25 to 30w...

 

[Ryuukon]

I would actually have to agree that it's bad for your device, but not for the reasons specified.

The E-Mech has a 7 amp limit. You're running at almost twice that. If the board in the E-Mech is rated at 7 amps, and it's putting out 12, then it's either got a faulty switch in it or no way to test the amperage it's putting out to make sure it doesn't pass the 7 amp rating. Either one is dangerous.

Either way, I sure wouldn't push it that hard. Just sounds like a very bad situation waiting to happen.

Do note that it's series batteries though.

 

[Ryuukon]

Frankly it doesn't matter if it's got batteries in series. The only thing that affects is the voltage output from the batteries. Doesn't do anything to change what the circuitry can handle. And looking around over the past 30 mins or so I've seen that the E-Mech is only rated at anywhere from 7 to 10 amps with NO ACTUAL official word. That is reason enough to be cautious.

Oh it matters a whole lot if the batteries are in series. For one thing, with regard to why I said that in response, is that the dual batteries in series don't mean the same thing as parallel batteries. With series batteries the capacity is effectively the same as one battery (though the lower amp draw means something).

Also, it actually does change something with regard to the board's power handling: it lowers the input current vs. parallel. So if the board can handle 10 amps INPUT, 72w would be within spec.

This has to have something to do with it, I don't have any reason to believe that my chip is lacking any functionality, I tested the cutoff functions carefully and confirmed them with an ohm meter, furthermore I've chain vaped it on numerous occasions over the past two weeks an noted no heat buildup or abnormalities in the units behavior

Curious about this board...and curious about this dr g. Can you say a little more about series batts and input current? I guess this is a buck circuit thing?

 

[rufus1138]

I think the batts are parallel btw

 

[ukeman]

Although I know nothing about electronics, I'll look into this some more as i did order one from AKA site, and want to know what would be the safety guidelines, whether limited to 30w or not...

* I have a Clouper30 box with a .6 ohms coil RDA on it, and vapes pretty good at 16 to 20w.

I've yet to make a 1 ohm coil to try yet but I would guess that range would be more ideal for these.

 

[xxvcrfuneralxx]

I talked to an everzon rep "person" and said that 1 ohm and higher builds were the ideal range he went on to say it can handle the lower ohms.. imho I don't think they were very well tested below 1 ohm. but I also sub ohm on this and have had it down to .3 ohms at 6 volts and had no problems besides cutting the battery time down considerably

 

[dr g]

Yes, since it is providing more current at input, it's a lower current to reach the same output power.

Makes sense, thank you
