Anybody Else? MC-E 4xAA Batteries, 350-400 lumens?

[jake25]

My idea involves 3xAA driving a Q5/single emitter

or 4xAA driving a MC-E

although, there are doubts that alkalines can keep up

 

[MichaelW]

3xAA driving a Q5 would be a good thrower
3x14500 [parallel] driving the MC-E would be the wall of light.

Fenix doesn't have a problem driving a Q5 L2D, so the extra cell should make it happen. Just don't expect flat output at the 200-250 output region, scale back expectations to 150-200.

MrGman what do you think about a 2S1P AA battery configuration to a Q5/single emitter?

Those exist already... Fenix, Eagletac and others have already made 2AA cree lights.

2S1P refers to 3 cells. This would allow it to push more current to the emitter. We all know that 2AA lights are usually not as efficient as an 18650 or 2 x 16340.

No, 2S 1P refers to 2 cells. Two cells in series. Generally one doesn't use addition to count cells when using this syntax; it's multiplicative.
2S2P refers to 4 cells, 3S2P is 6 cells, 3S (with an implied 1P) is 3 cells. Parallel batteries must always be of equal voltage.

It is not possible or safe to run 2 cells in series in parallel to one cell. You have two different voltages trying to run int the same driver that way. Things aren't going to be pretty.

I get what you're thinking but unfortunately I didn't make the rules, I just have to follow them.

 

[MrGman]

Two cells in series with no other cells in parallel is 2S. Why you should assume that the 1P is implied, I don't know. When there is 2 cells in series its just 2S. If you truly wanted to use it correctly with the complete series parallel nomencalture designation it would be 2S0P for nothing in parallel with the first 2 cells.

As for Jake. The 2AA cell flashlights abound they are called Fenix P2XXX whatever and are great. There is no way to put 1 cell in parallel with 2 of the same type. Its either 2 or 4. A four battern 2S2P configuration would work just fine and would probably use the exact same type of driver for the 2S configuration of a Fenix P2D, it would just have longer runtime.

But as I have said before I just don't get excited about multiple AA light configurations. Once you get to 4AA's I would much rather have something else in the Tube.

I know it's been said but I just want an upgraded Propoly 4aa.

I really like the idea of a 4AA like the ProPoly with a triple Q5 or R2 setup. I have a triple cree with 17mm reflectors in a 2D maglite and it has great beam quality. I have a 3D with a P7 emitter that had the stock reflector modified and it had a terrible beam. I added a Fivemega reflector and it was improved a little bit. I think a triple cree setup has the potential for better throw and beam quality in a smaller head. The new Eagletac M2 and M2X beam shots show the throw advantage of the triple. The triple 17mm reflector setup does not have the throw of the bigger reflectors but will fit in a small head and has a very desirable beam.

Thanks,
Alex

Q3 5A XPE. Nuff said.

It's now posslble: A Dereelight Javelin 2AA + two 1AA extenders. I'm about to receive a 3AA Javelin body to use at 3.6V (3x1.2V) with a Nailbender direct-drive MC-E. I'll drop in three lithium L91 cells to compare the results at 5.1V (3x1.7V).
