The i2, like it's predecessor, is a twisty style EDC/key chain style light, incorporating 3 basic modes for general use, and breaks down into 2 parts. The i2 is powered by either a standard AA alkaline or rechargeable Ni-mh (or Ni-cd for those that still use them), and does not support lithium ion rechargeable batteries. HTH

I wondered the same thing. Find this post. Can someone else confirm that? Thanks
yeah it seems to work well with 14500, the modes don't get jacked up sky high like on other lights
L and M seems to be about the same when using 14500. but H gets a nice boost
i suppose it would be safe as long as we use HIGH sparingly? what do you think?

Well...to say that implies that you know more about the driver circuit than the manufacturer. Those who made it do not claim it to be supported and that could be for any number of reasons all of which could merely be to avoid a lawsuit by an unwitting customer. I would stick with the specs unless or until I knew the driver wouldn't do something dramatic with a Li-Ion.
Have you tried yours I2 or just found that info out there?
Tried it in mine after reading about others doing the same. My observation was the same, where low stays low, medium stays medium, and high made me nearly crap my pants.
That said, I love my I2 so only had the 14500 in it for a few seconds.
Thanks, Jon. lol
So, looks like HIGH is DD, no? And other modes are regulated. What about heat? Definitely it should be warm in a seconds, but yeah, while they use the same circuit ITP used in their A series, no prob with 14500 (for short periods of time, of course) :devil:

the manuf may simply have not listed liion support coz of heating issues. the circuit may be perfectly capable of taking it
lightreviews simply stated the obvious that liion isn't officially supported which really doesn't help anyone on this thread

been using 14500 everyday for several months now
has not burned out yet...
so i guess it's safe to say that 14500's are pretty safe to use???

Hey guys, don't mean to necro this post but I have a little comparison of light outputs with a 14500 el-cheapo battery versus the Duracell AA the light came with.
First up we have the AA battery.

As you can see...the difference in brightness goes up each time you change modes. Low is pretty darn close - it's only when switching back and forth between the images that I can see a difference at all. Real world you probably won't notice it. Medium is affected pretty significantly. I'd say it's equivalent to the high with a regular AA - if not EVER-so-slightly more powerful. High...well you can see for yourself.
I was using a Canon Rebel XTi DSLR with fully manual settings. I tried to set the exposure to what I saw with my eyes - which was ISO 1600 with a 0.5 second exposure time. Nothing about the camera changed between shots so you can see an accurate comparison.
Distance from camera/light to the white plate was about 7 yards.
Interestingly but not surprisingly given this light's circuitry, the PWM frequency is very affected by the increased voltage. I can definitely hear the difference between the AA and the 14500 - on Medium the volume level of the PWM whine is almost doubled. It's also noticeably higher in pitch.
When it's not pouring down rain (if you couldn't tell from the pictures), I'll get my camera back out and try to do some distance shots.
With the above being said, I have to say that I can tell the light gets quite warm within seconds of being set to HIGH with the 14500 battery. I doubt it's -good- for the light, so I recommend limited use on HIGH. Officially, I say what the manufacturer says: "Not supported."
The good thing is these lights can be had for a little over $20 now, depending on where you get them. So, if you toast it, you're not out a huge amount of money.
