Quick provari question.

[Vapocalyptic]

I'm using a brand new efest 18350 with a kayfun at 1.4 ohm's. The end cap gets a tad warm. Is this normal? I'm I'm a trial run of sorts with it, I've got it on the classifieds but I'm debating on a future provari purchase., I have not owned it for more than a few days, and beforehand never gave a vv only device much thought.

I'm also wondering if a fuse is necessary. I know it's protected by the on board chips, but considering I have 7 mechs in heavy rotation, the fuse was second nature.

Thanks everybody

I would like to note it does cool down almost immediately, it isn't warm for an extended period of time or while not in use.

A fuse is not necessary at all in a regulated device. Your Provari is 100% fine without it.

 

[Vapocalyptic]

Alrighty, I'll be sure to remove it!

Trust me you don't need that fuse. Provari is very picky and will shut down in a heartbeat if the voltage is too high. A lot of times it won't let me go as high as I would like but that is good cause I know that im not going to wind up frying it.

Although the e fest might be ok, I would go with the recommended aw imrs. The provari shouldn't get warm like that and maybe hard to know what it could be. I would try a few things first before dumping because the provari is the best. Use recommended battery also clean all contacts with a metal polish and q tips. Not only the 510 pin but the one inside.. Also the 510 connection with the atty must be good, sometimes the 510 pin on the atty can be not reaching quite enough and cause issues. I know the kayfuns 510 pin is not adjustable but maybe just a smidgen turn to the left might work. Does the provari get warm with other attys also?

Also totally agree with stevegmu, Don't do the fuse thing.

Drop the fuse. Try cleaning the threads of the end cap (and the threads that it screws in to).

Check to see if you've dislodged / loosened the chip set or collapsed the base cap spring by inserting the fuse & button top battery together in the tube.
I can't see how both would fit without a good deal of force while reinstalling the end cap.


I could be wrong, but, I don't think countless provari owners use efest batteries.
Independent tests by battery experts have repeatedly stated quite a few efest's don't live up to their advertized specifications.
The Provari protection circuitry will trigger when an unsafe or out of spec condition is detected and give an error code or shut itself down depending on the severity of the issue.
Using the efest wont cause an unsafe condition, if it can't supply the power necessary it might degrade performance slightly.
The manufacturer states their reasoning's why they recommend a certain battery on their website.

If you're comfortable using efest batteries, use them,, I hope you enjoy your new acquisition.

Also like mentioned above, it could be the spring not making good contact, before messing with the atty you can unscrew the spring and fluff it up and reinsert. This could very well be the issue

Provari's along with many other regulated devices essentially have fuses built in them. You don't need one. It's part of the programing in the chip. AW IMR's are recommended because the Provari's chip has been specifically programmed to work with those particular batteries, with those particular specs. You got it off the classies, so it's likely out of warranty, but normally using anything other then an AW IMR in your Provari will void the warranty, and I imagine there's a good reason for that.

 

[Tinkiegrrl]

Oh! Which version Provari are you using? V1 I hear, didn't handle low res coils well. You need to use standard resistance for that version. The latest one, version 2.5 wouldn't have any issues with a 1.4 ohm coil.

Just a quick reminder about the rules, please refrain from attacking each other name calling ect. the OP has asked for assistance and advice, please offer that or move onto another thread. Thanks!

 

[TFL!]

IF it is a V1 you might be able to have it up dated email Pro Vape to find out.

Bottom cap getting hot on a provari is abnormal... I would email provape and ask for advise there.

 

[DaveP]

Provari V2 and 2.5 handle 3.5 amps before kicking out an error code. You can calculate what it takes to create that sort of load using the Ohms Law Calculator.

Enter the voltage setting of the Provari and the resistance of the atomizer coil and it will give you the current in amps and the power in watts. You can play around with various voltages and resistances to see what works under the limit.

Not if you stuff a vapesafe fuse in it along with an 18350.
The two conflict/interfere with each other and could cause damage to one or both, heating of the positive or negative contact areas would be one result.

Provape recommends AW IMR batteries. Not eFest or any other brand.
AW
AW
AW

So before you send the Provari back or do anything else get some REAL AW batteries. Be careful as there are counterfeit AW batteries around. The newest AW versions have a hologram AW sticker and it is silver in color.

I have a V2.5 Provari and I've used both 18650 and 18490 AW batteries in it and have never felt the bottom cap get warm.

What voltage are you running it at?

 

[DaveP]

My Provari bottom cap has never gotten hot. That would almost certainly come from the battery you are using. Is the battery getting warm and transferring the heat through the spring in the cap?

I keep my Provari in my pants pocket when I'm out and walking around. Sometime, when I pull it out of my pocket it's warm from body heat, but cools off as I vape. That can feel like the heat is from vaping if you don't realize it's just body heat transfer that was there before you vaped!

Also, you said in the OP that you were using an 18350. That's a really short battery. The Provari V1, V2, and V2.5 only use 18650 and 18490. Yours must be a mini that uses the 18490 or the 18350.

I have to disagree. That is IF the fuse is just a fuse. Fuses don't have resistance, or they shouldn't have any resistance. The just break if the amp limit is surpassed.
