First off if this is in the wrong section then oppsum (?)

I have a aw imr 18490 battery for my bolt and long story short, i checked the volts on it last night which was around 3.6V, then forgot to check it as i used it today. The Bolt just stopped working, i checked to make sure it was not the cart then called myself a few choice names when i realized the battery was too low to power the bolt.

When i checked the "dead" 18490 i was sitting at 2.3V which i put on the trust fire tr-00 to charge, and put a fresh battery (only have two of them) in the bolt and i am off to the races with the vivi nova again.

So my question is, is there a certain level i should remove the 18490? is charging it from the state of 2.3V going to cause it, or the bolt damage? I am asking as i thought i read somewhere on ecf that if they get that low you need to toss them?

I mean if it is more then safe to allow them to get too low then yeah for me, though with the vivi nova on there i doubt it would allow that as the bridgeless atomizer and kanger did.....

If the battery charged up OK and you were able to vape with it, I wouldn't worry too much. Don't make a habit of it or you will most certainly destroy the battery.

That is the problem with using an unprotected battery with a device that won't cut it off should the actual battery voltage be too low. Any mechanical mod or simple unregulated mod will most certainly be able to over-discharge an unprotected battery. But it is best to remove and recharge that battery when is gets down to about 3.2 volts or so. Over-discharge GREATLY increases the risk of battery failure.

no , Imr batteries are not protected because they have a safer chemistry...basically they say that if they go thermal they won't start a fire....anyway for the op, get yourself an extender cap for your bolt and a kick by evolve and you'll get a better vape and it will cut your battery off at a safe 3.2v so you know it needs to be charged

Here's what happened to me: I had an ePower battery. I charged it normally, no problems, read 4.1V. I stuck it in my pocket, along with my ePower & went to work. I vaped on the ePower all day until the battery inside it went dead. I installed the charged battery in it, the battery was dead, no vape at all. When I got home, I checked the battery with my voltmeter, it read 2.4V. I put it on the charger, got green light, it never turned red. Battery is done, it must have shorted against the ePower and/or pocket change. Lesson learned - put spare batteries in a plastic bag before putting in pocket. (I let the battery just sit on my desk for several days & the voltage came up to 2.8V, still wouldn't charge.)

I was thinking on getting a kick, but was not sure with just having the 18490's in there if i needed a extension cap or not for the kick now i know i do need that first. Seeing as i have three evo's, and the revolution 2 (which i use as a pass through box mod more then a bottom feeder) i thought i would get a bolt for those times i would need the lower volts like a ego (without the ego's airy like draw)...i had no clue i would like it so much in the mean time

So far the charging went ok, as for vaping on i have no real clue as soon as i did the volt meter i slapped a fresh battery into the bolt as the other one that i had drained down to 2.3V was charging. When i removed it off the charger i got a 4.2V reading last night and i checked it again and still got a 4.2V reading. I have not placed it in the bolt right now, as ......well a bit of paranoia and wondering if i am still risking being put into low earth orbit lol. But i will try it a bit later today with just a bridgless LR 510 atty and keep a eye on it.
