My Provaris are driving me nuts!

[MISTERDIEABETIC]

Ok, I need y'alls help with this. I have 3 Provaris (Full size v1, and 2 v2 minis). Two of them (my girlfriend uses the third so I don't know much about an issues it has) almost always shuts off prematurely due to "low battery voltage"
Now my mini just did this to me again a few minutes ago and I've tried everything I can think of, but to no avail. I pulled the battery out after it started rapidly flashing and checked the voltage with my multimeter- 3.75V. Reinserted the battery into the provari and checked voltage with my kayfun attached-3.2V Then took the kayfun off and checked it with no load-3.7V
Why am I losing half a volt with a load? It used to only drop .1 or .2 volts but this is ridiculous!
And yes I have cleaned the positive battery contact with alcohol, cleaned the threads on the battery cap (which even with cleaning with a q-tip and alcohol, I get this almost black residue everytime and it comes back just a few hours later and not a clue what it is) I've also stretched the spring some, tried a different end. Everything!
My full size provari kept doing this also which is why I switched to the mini. This is the ONLY complaint I've ever had towards any of my Provaris. It just gets very annoying after awhile of having to keep pulling the battery out and reinserting it just so I can vape. I'm using brand new aw imr batteries.

Can anyone shed some light on this and possibly have a better solution than constant battery removal??

I've never even heard of that issue, much less experienced it myself. I would contact provape and have them sent in if you can.

I currently get 3.8 with kayfun on, and 3.6 with kayfun removed a .2 difference which I believe is normal. I'll let more exp users to fill in the gaps. My light won't start flashing to around 3.2 or 3.4 I think.

My build is 1.5 ohm micro 28g kanthal

More info is needed what is the olms on the build in on the kayfun?

Not what I was thinking. But the Pro Vari checks Volts under load so a MM will read higher.
Only thing I can think of is try other toppers or a new build on the kayfun.

Sounds like the 510 connection needs to be cleaned thoroughly and/or the positive battery contact inside the tube needs to be cleaned with a pencil eraser or very gently with 400 - 600 grit emery cloth.
I suspect the black residue on the tube / cap threads coming back quickly and the increase in the amount of v drop compared to normal is due to the above.

My provaris are covered in grease, oil, diesel, water, sand, mud, blood & cow poo every day, I clean the bottom cap & body threads once a week and there is just a little to remove each time.

The provari checks resistance and battery charge under load which explains the difference between battery out/multimeter and what the provari shows with or without your delivery device attached.

Note to self: never buy a used Provari from Topwater Elvis

Sounds more like the battery than the device. how old is the battery ?

All of mine do that. A fresh battery may read 4.2-4.1v when I check the battery with nothing on top, but depending on the device I attach nothing may change or it may go down a notch or so. We had a thread about this before. I seem to recall someone said it had to do with firing under load and reading the voltage available when using the device. Currently, with a tank on my Cb reads 3.9v, but when I take the tank off it reads 4.0v. It doesn't happen with every topper I put on, but I've had every ProVari do it. I don't know it the available voltage theory is true, but it sounded good to me at the time.

I suggest cleaning the battery end cap threads with some Noaloxx. The end cap is part of the battery circuit. If the threading is dirty the Provari will sense a conduction issue and the low battery warning (blinking) will activate.

If you've never cleaned your end caps threads this is likely your issue.

That stuff is nasty. It attracts dirt big time. I just clean my threads with Isopropyl alcohol and a tooth brush.

It's not meant to be kept on the threads. It is an anti-oxidant, which is like a rust-remover and prevents eventual "locking up" or freezing of metal threads. Apply only a small amount to the threads, install the cap on the Provari and work it in...back and forth. Then remove the Noaloxx with a cloth. The bare metal threads should be shiney and clean when finished.

Ohhh Lol !! Thanks man

You have some older Provaris, perhaps they need a firmware update to better handle newer batteries and toppers.

2 are brand new and the other 2 are 2 months old

I clean them almost daily with isopropyl alcohol and a q-tip
