Gave some more charge to the LiFe 14500s and the NDI now turns on, but keeps flashing the low-voltage warning and can't be used normally. Oh well.

Sure they're charging properly? I don't have any experience with them, but from what I know, they should charge to about 4.2V and 3.6V is nominal. They're probably dead at 3.4V but I'm not sure about that.
Probably have to put them under some light load in order to get accurate voltage levels.

I have a RC-grade charger that can charge A123 and other LiFePO4 cells. It charges them just fine, it's the low-voltage warning that screws things up.
Edit: I forgot to mention that the cells I just tried after giving them some charge were the LiFe ones, not the ordinary LiIon 14500s. The NDI works perfectly on those.

Which I believe are 3.0v cells? I'm pretty sure they say 1.2-1.5 or 3.6V.

3.2 nominal.

Yeah, a 3.6V lithium at 3.2 is dead as a doornail, so those wouldn't work.
I can't speak for EdgeTec, but from what I've gathered the NiteCore DI was designed primarily for 14500 and have built-in protection for them. Typical 14500's are 3.6V, although the LiFePO4 are becoming more available.
They couldn't have built-in battery protection and supported both 3.6 and 3.2 lithiums. I suppose they could have had some programming method to switch between the two, but that just complicates things.
I have heard some people saying ditch the protection and let people worry about it or use protected cells, but I think NiteCore wanted people to not have to worry about the battery. If you're using it in a tactical situation you don't want to think about over discharging your 14500.
Then again, if you're in a real tactical situation, I suppose you wouldn't care if you have to replace a battery.
Personally I think flashing is better than dead cutoff like a protected battery will do. But I'm still bouncing back and forth between getting a 14500 and just buying a bulk of L91's.
