4AA That Runs On 2?

I was looking at the Sofirn SF11. I’ve never owned a soda can light. I carry extra Eneloops for the GPS when out with the hounds. Thinking might as well carry them in a light. Will any of the 4AA lights run on 2 batteries?

I have a Nitecore 4 x AA and a Led Lenser 4 x AA. They both need 4 x batteries,

Have a Sunwayman 4 x AA and a Led Lenser 4 x AA. Both need 4 batteries (6V).

I own a few lights that can cope with 1.5V (AAA/AA) and 4.2V (10440/14500) thanks to the drivers.

I’m pretty sure some drivers can cope with 2×1.5V AND 4×1.5V, but can’t say which ones.

You are a flashaholic if you are forced to come out of the closet, to make room for more flashlights.

Its a 6AA not 4, but my 5.11 XBT A6 will run either 3 or 6 cells just fine. Just affects runtime. Perfect truck light, BTW. Just can’t find them anymore. (Nor can I get the head open to try an emitter swap)

Unlikely. Most AA lights will stack 4S to get (nominally) 6V and then buck it down to LED voltage.

TN4A, TK4A, SF11, EA4, etc., all have 4 in series this way. The EA8 takes 4 or 8, so 4S1P or 4S2P.

Really doesn’t pay to make a light that can take 4 cells, yet parallel them and thus need a boost driver that’d get any appreciable current to the LED while torturing the already hateful little alkaleaks to piss them off and bring out their nasty side even more.

And with 4S, yeah, you can run NiMH cells and still have 4.8V to play with.
