Hi,
I'm still trying to get the hang of all the 'exotic', non-standard AA cells. So, forgive me for asking questions that may be stupid.
First of all, I view the LiFePO4 batteries as a compromise between the Ni-MH AA's and the 14500 Li-ion cells.
The LiFePO4 is higher voltage than the Ni-MH but lower than 14500. While capacity is lower than the Ni-MH but not as low as the Li-ion.
Please correct me if I've got this wrong.
In almost every spec Fenix provides for their flashlights the LiFePO4 is listed as a big no-no. Was I surprised to find out there was nothing of the sort in the specs for my HL35 headlamp. See for yourselves:

Nothing... So, what does it mean? Can I just use LiFePO4 batteries with this light?
I had something like this in mind:

1500 mAh is not so bad, when compared to the 800 I (would) get from their Li-ion 14500 (Fenix). These cells are supposedly 'protected', plus the brand ain't so bad. I've used their Lithium primaries before and they worked great.
Maybe I'm missing something here.. Like, what's the catch? They leak? They blow up? They can't produce enough current to properly drive a powerful LED?
I know I won't get with them the advertised 450lm out of my HL35 but I'm fine with it. I just don't want to make a stupid mistake like ruining my headlamp or getting chemical burns from the hot acid leaking out of the headlamp, running down my forehead and into my eyes...
So, what do you think?
And how do I even charge the LiFePO4 cells? All I have so far is the Fenix ARE-C2 charger. It don't say nothing about LiFePO4. Is it safe for that?
Also, I need the LiFePO4 batteries more for my Nitecore MT10A than the Fenix HL35. Using these cells with this flashlight kinda makes sense to me. I don't need the maximum rated output. And the runtimes with the Li-ion's are too short. So, how about using the 1500 mAh LiFePO4 instead?
In the manual it says "Primary LiFePO4 battery". Here, check it out:

Like, what's primary LiFePO4? All I know is the rechargeable type. So what's the deal with that? Do you think I can use those Etinesan LiFePO's in my Nitecore MT10A (safely)? And what about the over-discharging?
Thanks!
