Anyone tried the L1T on Li-Ion? The board is supposedly good for up to 4.5 volts input.

Wondering if at that voltage of the Li-Ion that it steps down, or it just lets the whole thing through.

Any any report of effect on brightness?

Thanks,
Mo

In my testing - it is nice and bright (comparable to the L2T with 2 alkalines) and seems to fall within Fenix's voltage specs - I found the light gets fairly toasty if run for more than a few minutes at a time. I only tested it for about 10 minutes though so YMMV.

It definitely works, and mine didn't explode, but the high/low mode doesn't work without some modifications to the head. If you put a 3V lithium primary (extracted from CRV3 battery) into it it's almost as bright, well within Fenix's voltage specs, and high/low works fine.

I use 14500 in an L2P head/L1 body/2 stage tail light instead.

check my "Fenix L1T and 14500s"-problem tread....

no problem to run the light with a 14500 till the circuit stops to protect the batt, but just some time ago, I noticed, that the light draws 1 Amp from the batt, so the 75 mins runtime is not possible.
(and, still, the low is too high) ;)
