Provari /AWIMR 18650 weirdness

[Jake Dubbya]

HI Folks
Here's a weird thing:
Sometimes my Provari 2.5 starts to flash, indicating the battery is low- I'm not sure why but I unscrewed the battery cap and then tightened it again and the flashing stopped. When I checked the battery power, it showed 3.6 volts and carried on working for an hour or so before the battery finally ran out.
Could anyone explain why this happens? The batteries are 2 months old and get charged in an nitecore i4 charger.
Thanks.

Not entirely sure about the technical process, but I believe that by removing the battery momentarily resets the micorprocessor's low battery sensor. Some Provari owners have known about this for some time, and do exactly what you described to get additional battery time before seeing the flashing light again.

Ok, just a little anomaly I can live with. Thanks!

Iv heard the nitecore i4 is not the best charger for our batteries.

Our batteries are not designed to be quick charged, this can degrade the chemistry in the battery, and might be a cause of this behavior. (Or it might have nothing to do with it).

I only use a pila charger and have the same issue in one of my version 2.0 provari's

Had similar issues with mine at one point. Cleaned the contacts and threading. Applied some Noalox to the threading, and issue gone!

Might help ya!

It appears that this behaviour is by design. Let’s say that the low battery indicator is triggered below 3.3V; I’m not sure exactly what the low voltage limit is, but it’s easier to explain with a number figure.

Now, it appears that the low battery flashing light is latched. That is, if you’re holding down the button and the voltage momentarily drops below 3.3V, it will start flashing. But, if you release the button and the voltage goes above 3.3V (3.6V in your case), the flashing will not stop.

With the light flashing, if the battery is above 3.3V and I cycle power, the flashing stops on my ProVaris, until it goes below 3.3V again. I also noticed that turning the LED off and then on again (last menu item, “Lo”), will stop the flashing as well, if your voltage is above 3.3V.

I hope this helps.
