The IMR's are a safe chemistry batt and don't require a protection circuit. - Though there was a thread about three weeks ago with some pics of a blown AW IMR, so perhaps safe chem should be taken with a grain of salt.

The protected AW batts are li-on. Any li-on batt used in a mod should have a protection circuit (and they do).

The IMR's have a higher C rating. That means they can produce more amps while discharging. The Li-on's have a higher mah rating which means they take longer to discharge.

I use both IMR and regular protected 18650's in mine. The IMRs are the most consistent. I've had certain combinations of voltage and resistance that the regular 18650's just couldn't handle, but usually they're just fine. The end cap won't screw on all the way with the regular 18650s and the low bat warning doesn't work, the device just dies without the blinking light. Not a big deal really. I've never had any 17670's, but if the designation is to be believed, they'll be a little longer than protected 18650's. You could always slide an o-ring over the end cap if the exposed thread bothers you.

When I bought mine, only the IMR's were recommended. I usually vape low 4s with 2.3 ohm atties, so I don't think my normal amp draw is too high. Higher voltages or low resistance might not work as well without the higher c rating of the IMR.

I use nothing but the AW IMR 18650's or 18490's that Provape recommend and that I bought with the device from them. They designed the device, they did the calculations, they say that the IMR is the battery that should be used. Taking into account I would have to send my PV over four thousand miles and be without it for near three weeks for warranty repair I simply will not risk using other than the recommended spec. I also paid the extra for the second year of warranty. I wonder what would happen if Provape refused a warranty claim because non-recommended batteries were used which damaged the circuit board. It is not beyond the realms of possibility for this to happen, or for it to be detectable.

I collect high power LED torches (flashlights) that run on LiIon batteries, and often multiples. I do know enough about these cells that they do not suffer any form of abuse gladly and I would not stick even a top quality normal black and silver 18650 in a metal tube and hold it close to my face all day when the device requires a high drain IMR. As for using a cheapo trustfire flat top with a magnet in the PV, well, someone is going to get hurt soon in my humble opinion. I won't risk it.

Of course I could just be an over-cautious old fart. YMMV :)
