OK, gotta ask, my OCD is kicking in again. Provari mini 2.5 is giving me two readings on the CB function. One reading with an rba on it, another with no atty at all on it. 18650, 18490, 18350, battery size doesn't change it, if anything the spread is bigger with the small 18350 batts. If the CB reads 3.7 with the atty on, take it off, reads 3.9. That, I could live with, kinda, but, it also gives me the low battery flashing button at 3.7, which, has started to annoy me. greatly.

take the battery cap off, take the atty off, resets it, it reads right, back to happy. but, WTH, it shouldn't be giving me a low battery blink at 3.7 anyways...

It does this every time, gives me two readings, one with atty on, one with atty off. almost always a .2 spread, verified the battery charge with multi meter. the CB function reading without the atty is true and correct. put the atty on, and it almost always reads .2 low, which I could care less about really, kinda, but when it trips my low battery flashing at 3.7, which actually is 3.9, you gotta ask yourself WTH. While typing this, it gave me a low battery flash, checked it, said 3.3 on CB with atty on. Took atty off, CB function says 3.8 and still flashes. take cap off, cb reads 3.8 and stops flashing because it was reset.... this is after I have cleaned all contacts, repeatedly, it's not the coil build or connections, I've checked, repeatedly, 1.5 or 1.8 ohm coils, nothing below that, I don't build low ohm coils for the prov, keep the sub ohm stuff on a mechanical. new AW and 3 month old ran in rotation batts, all three sizes.

contacted CS at Provape, they said I could "send it back", and to be honest, since I can document and duplicate the device readings every time, with AW batts, I am pretty reluctant to be without it, for them to wind up saying nothing wrong, be without the device for a week or two, and get it back as is. I emailed them in detail what it was doing, what it was reading. "don't know" or "nothing wrong" isn't really the answer I was looking for. This is what it's doing. there can only be a finite amount of variables, trouble shooting the reading should be fairly straight forward? no? anybody know the math behind these readings?

at first I thought it was my RBAs, just thought I was getting less battery life. it blinked, i read it with the atty on, changed the batts. but since I noticed dual readings, I have started having to take two readings, one with atty on, one without, and then unscrew the batt cap to get the device reset.

Anybody have a guess?

As always, thanks in advance.

To the OP. 2 things:

All ProVaris will give you 2 different battery readings, 1 with no load (no atty) and 1 under load (atty attached). The truer battery voltage remaining is with no load. My rule of thumb when checking the battery left is to either remove the atty and check it, or I just ad 0.2 volts to the reading under load (so a 3.7 v reading under load, I'll assume the battery is at 3.9)

Now, OP, you said that you are running an RBA. What is the resistance on it, and how many volts is your ProVari set to? Also, when the light is blinking at 3.7v, is that with the atty attached or not?

My theory on that is that either 1) you are getting the blinking at 3.5 under load and 3.7 no load (totally normal) OR you are using a pretty low res atty and with your settings requires higher amperage, causing the device to throw the blinking LED a little sooner than normal.

running 1.5 ohm single coil at 4.0v or 4.2v. yes, atty attached low battery warning blinking at 3.7v, take the atty off CB reads 3.9v

blinking at 3.7v under load, 3.9v no load.

Per ProVape's ProVari Owner's Manual.


WARNING: Never use your ProVari without a atomizer. Do not connect to a volt meter without a load as high voltages without a resistance can damage the device.

?????? don't get it. i'm not running sub ohm or at high voltages. why the OM quote?

Well - I can't answer your question or offer you too much help but I just tested my battery on my new 2.5 mini with my atty on it and it read 3.5 volts. Took the atty off and it read 3.7 volts.

Dun. Dun. DUN.

is it throwing the low battery blinking in the mix on you yet?

Think about it.


- Andy . . . Challenge the day.

ok, it is written with bad grammar, should read "without "an" atomizer", not "a" atomizer...?

1.5 to 1.8 are low resistance, not "no" resistance.?

i don't connect the prov to the volt meter, i take the batteries out when I meter them.

Andy, I'm missing you on this one as well. I think you are taking the first part too literally and by itself, rather than it directly being associated with the second sentence. It would appear that you are saying at you should never check your battery voltage without an atomizer attached?? Tat doesn't make vary much sense, as that is the only way to get an accurate voltage reading of the battery without taking it out and using a multi meter.

ID venture out there and say that there is zero wrong with using menu functions without an atomizer attached.

blinking at 3.7v under load, 3.9v no load.

I would try cleaning all your contacts (spring, pos pin, center pin, battery threads) and see if that makes a difference. Otherwise, just contact ProVape. They'll be able to answer questions for you.

Another question?...At what battery voltage (under load) does your ProVari die? It should be around 3.3v.

I did take the batteries out to verify they are charging, and at what level on a meter. verified by the prov itself, with no atty. I never ran the multi meter on the prov, just on batteries, out of unit, to verify which reading was "true".
I started cleaning contacts, all of them, every day, and since, when I first noticed this.

to answer when the batts actually die, and at what voltage, I never did let any of the batteries I use in rotation go all the way to "not working/empty except for two occasions. Figured it was hard on the batts to let that happen, so I usually changed them out before the device shut down due to charge. First occasion was just to see "how long" they ran before shutting down, the next was at Provape's request.

I have contacted them with the info, and corresponding numbers. But like I said, to send it back and be without the device is kind of a crap shoot. I could get it back as is. It's not that it doesn't work, and unscrewing the battery cap to get it to reset is what I have opted to do. I told them what it was doing, and they said my warranty isn't voided, so, I'll just keep resetting the cap for now.

Bad part for me is I wanted to pick up a second unit for back up, but now, since nobody really knows why it does this, if I buy a second unit for back up, it could very well do the same thing.

Like I said, it works fine, except for the early warnings, which, are annoying. lol

Well, I'm not sure I understand what about sending it back to ProVape is a crapshoot. Turnaround is usually less than a week. Anyway, with what you have said, I have one final suggestion:

Turn off the LED. Then you won't have to worry about any flashing. Also, letting your batteries run dead in the ProVari is not at all hard on them. It cuts off WAY before you'd ever reach that point (< 3v).

yep. turning the LED off is probably the way to go. I really don't want to send it back. It's all that stands between me and an Ego battery, or a mechanical. I've emailed them the details and numbers, so if they don't know from that and can't apply those numbers to trouble shoot it, why bother sending it in and being without it, to get it back doing the same thing. they said it didn't void the warranty, so, ignoring it, resetting it or turning off the LED is probably the way to go. i just figured the numbers would indicate something specific. thanks, appreciate it.

I am having same issues as op and mine is 3 weeks old. I got the usual responses to clean it but made no difference. Mine with blink at anywhere from 3.4-3.7. And it is random. Sometime at 3.4 for 2-3 cycles and then 3.7. Let me know if you figure it out. By the way cleaning doesn't help but didn't hurt either.

Hey, Tommy. I interpret ProVape's comment, as one should check the battery's status with an atty attached and not without one attached.

In CB mode the ProVari fires with or without a device attached, as I understand it.
