Battery question

[rastapete69]

I'm a few days into my Provari ownership and haven't touched my MVP since as I am very impressed with the Provari.

My experience with batteries has been limited to mechs, where I changed out 16500s quite frequently and charged the MVP every 2 days and never worried, even with heavy vaping.

I have a couple AW 18490s and 18650s for the Provari and was impressed how long the 18490s lasted, which was most of the day.

My question is;

When checking the battery on the Provari, what level is it getting close to blinking?

I seem to recall reading it will shut off at 3.2

Roughly the 3.3 range. It's better to charge them early (they don't develop a 'memory'). Most folks like to pull them at 3.5-3.6

Yep - 3.2 is shutdown time.
I have, once or twice, thought "hmm - is the battery fading" because the vape changed a LITTLE - and checking, found it at 3.3.
But most of the time, I can't tell, it stays solid right up to blinking.
And once it's blinking, you don't have too many hits left...
My guess is that it blinks at 3.3, but if unused for a minute, might "recover" and read 3.4 - but it's around there somewhere.

So, I JUST got a blink, and immediately checked: it was at 3.5.

Not sure if it's part of the calculation - it could be - but I'm running at 4.4v/2.2o

With my Vamo I always stopped and charged at 3.6 cause thats when I could tell the battery was going cause the vape wasn't has good. Im having problems with the Provari though cause like its been said...good to the last vape!

I don't think it's just the voltage. I vape on my Stealth more than my stainless, so I don't keep track all that well. I know I've had it to 3.4 without any blinking though. It may have something to do with the power (watts) or amperage being drawn... which the age of the battery could also effect. In my digging around the Provape FAQ I didn't find anything definitive on it... not that it's really that important. I still swap mine out at 3.6 most of the time. Currently I have 3 batteries for 2 Provaris, so if they're both at 3.7 (or 3.7 & 3.8), I'll even swap one early. I'm ordering 2 more batteries & a new i4 charger next month so that won't be as big of an issue. 3.5-3.6 is still the best time to swap them out regardless.

I'm the same way. When my vape changes I know it's time to change the battery. I don't even wait for the blinking lights.

The battery check doesn't put the same load on as it does when your firing your device at 4.4v, which is using the boost circuitry. So seeing a bigger voltage drop under the bigger load is normal. No worries there. Just pop in one of the other 5 charged cells and vape (can't have too many charged batteries)

Lithium batteries don't develop discharge/charge memory like NiCad or to a lesser degree NiMH. That's one of the good things about lithium technology. And if a battery is rated for 500 charge cycles, charging at half charge (around 3.7 volts) only counts as a half charge cycle (so you can charge cycle 1000 times that way. Same difference either way to the battery). So no reason not to charge early if you have spares. You're always topped up and ready for a long vape session. I almost always do it this way too.
