No, that isn't normal. Do you just have the one battery? My understanding of the cut-off is not based on the actual voltage of the battery, rather its ability to meet the 2.5 amp current limit. When the battery is no longer able to supply the current to meet the output voltage you have it set to, the provari will blink the led, letting you know it's time to recharge.

What is the mah rating for the battery? You may have a bad battery. I'd suggest trying a different battery and seeing what it does. If you have another battery that does the same thing, I would contact provape to see about having the provari checked out.

Yes,it is normal.Provape recommends recharging the IMR's before they cut out,it will increase the longevity of the battery and decrease the likelihood of over-stressing the battery.The low battery indicator is a feature I wish the provari still had,My first run red led has it and my blue led don't,so I just change batteries daily,I have been getting ~4mls before the low battery indicator flashes.These batteries don't develop "memories" and recharging at 3.5-3.7 will increase their lifespan

You don't HAVE to recharge at 3.7,but its better for the battery not to go too low.personal preference I guess.I could get another few hrs after the indicator flashes(I've done it several times)but a fresh charged 18650 goes about 14hrs (for me)before it hits 3.6-3.7v,So its no big deal to swap batteries once a day.

So your blue-LED doesn't have the low-battery indicator? I use it every day. As soon as it starts flashing, I replace the battery to hopefully prolong their life.

Hmm, maybe I need to replace my spring then. I slipped away from these forums after getting my Provari and am just now coming back to see what is out there.

I love my Provari but man does it drive me crazy with it's constant blinking. I can put in a fresh 18650 battery at 4.2 volts, and get the blinking pretty quickly when the battery shows 3.8 volts. Every battery I have starts blinking right in the 3.7-3.8 range. I actually sometimes grow so tired of it I set the provari down and just use an Ego.

yeah, they came out with the spring a while ago, and you can get them at Provape... they might send you one on warranty.

I's it difficult to install the spare spring? Any special tools needed or is it as simple to do as a Reo? How would you know when to replace the spring? Just wondering if I buy a Provari if I should pick up some spare parts.
the new provari's have been coming with new spring.
it's a bit of a bother to replace, but if i can, anybody can. You have to get a blunt tip like a thick flat screw driver and push it into the groove at bottom of the cap. If you have both short and long cap you need one for each.

Thanks ukeman. Sorry to hijack the thread, but just one more question. Does the spring ever collapse or the safety features on the provari prevent that from ever happening?
never heard of it happening in the couple years the Vari has been out.
not tech enough to know about that either. Provape has unbeatable QC and CS ... that i know.

One more suggestion. Try giving your Provari a thorough cleaning. My original black textured provari was notorious for premature blinking despite having replaced the spring. My newer satin one has started doing it also. It was flashing me this morning and the battery was reading 3.8. When I was only using the black one I found it needed a thorough cleaning about once a week to prevent the premature blinking. I use a q-tip dipped in alcohol to clean the post that connects with the positive end of the battery. Clean the threads and the endcaps under the spring. Then apply a small amount of noalax to the threads. I am usually gtg for a while after doing that. Between cleanings just unscrew the endcap to break the circuit, then screw it back on. This will stop the blinking for a while.

If it does I can't see it.I do have the button LED turned off(don't need a glow to know its working)maybe that's why.The red LED provari does tho.Charging before 3.2-3.3v will extend the life according to everything I've read in the last 18 months.
Instead of counting as a full cycle(full charge,dead battery,full charge) it only counts as half,These batteries are supposed to be good for around 300-350 cycles,as I understand it,repeatedly going thru a full cycle builds up internal resistance,and the cell is not as efficient at holding a charge,I am probably wrong,I'm not an electrician or battery expert.I have used the provari daily for the last year,and my AW 18650's last longer now than they did 6 months ago.

I can't dispute your claim on longevity with allowing the battery to drain to 3.2 v as opposed to 3.7, but I am using 3100 mah protected aw ic's, and I'm getting about 1 1/2-2 days, per battery (heavy vaper) before needing a recharge. If each of my 2 batteries gets me 300 charges, that's about two years on 2 batteries. Even if they last me a year, at $20 each, that's well worth my money and the convenience of not having to worry about taking them off early to try and maybe prolong their lives. Plus the fact that I use a pila charger means I don't have to worry about the problems associated with cheap chargers prematurely wearing out my batteries. Just my $.02.
