14500 3.0v Interest Thread

[UK Dazzler]

Hi Guys,

How many Fenix L1x, Jetbeam AA and ultrafire AA Light owners are their out there?

How many of us (myself included:naughty have inserted a 14500 3.7v Li-Ion batt to see what their light can really do!?

As we all know sticking one of these cells in our beloved lights gives us the wow factor but we all admit that the lights get hot very quickly and prolonged use really does run the risk of frying the LEDs in our lights.

I believe that a regulated 3.0v version of this 14500 cell would be much more compatable with todays AA flashlights especially with the Fenix L1D-CE range which has the same head as the L2D therefor having an input voltage of 3.0v. We know already that the light does not run in regulation with the 3.7v cell.

This cell would also be ideal for the Jets, Ultrafires, Lite flux, and the up and coming Rexlights, which are all probably rated to 4.2v but would run more comfortably on 3.0v and stay in regulation so all modes work and keeps the heat down!!

I have been in touch with AW about this idea and he says if their is enough interest, it may just happen!!:rock:

So how many do you want then!!?

What do you think?

All the Best

I could well be interested. Very interested. But I'd want both AA and AAA - and would probably prefer AAA over AA.

But I guess it would mean another new charger

Please me know how it goes.

Thanks,

I also would like both aaa and aa size 3.0 v batteries

 

[Thujone]

I would like both as well.

Please me know how it goes.

No and I don't want to!

I'm in for a for both AA and AAA sizes...

This could be very interesting indeed. There are, of course the drawbacks of needing a new charger, the cost of new batteries, the confusion of having to keep straight now 3 separate battery types all of the same size and shape.

BUT, having something you're able to drop in and get the boost in performance without the drawbacks of overdriving the emitter as much is attractive indeed.

For me at least, a key factor in the decision is going to be price. If it can be done for as much or less than present 14500's, I would be interested.

I'd like 141000 duable length AA's that pump out 3 volts and huge capacity.

I'd like 141000 duable length AA's that pump out 3 volts and huge capacity.

This would be fantabulous. I dont see it happening, but wow. That would be great. :rock:

I'd like 141000 duable length AA's that pump out 3 volts and huge capacity.

THat would be awesome! I'd also be in for a 3v 14500.

I'd like 14500 duable length AA's that pump out 3 volts and huge capacity.

It may be possible to make some sort of parallel-adapter with an insulating spacer in between two cells that would have small wires to connect the negative and positive contacts in the middle to the contacts on the outside. That would make a good drop in for even direct-drive 2AA flashlights.

I definitely like the idea of 3.0V 14500, a lot of AA flashlights that use boost circuits to boost from ~1.2 V to ~3.3 volts simply do nothing and direct (over-)drive the LEDs with a 3.6V cell. A 3.0 Cell would mean the converter wouldn't have to step up as much (less current, higher efficiency) but it would still maintain constant brightness. Also, if they ever get those Rexlights out, I like the idea of having a recharageable for common use, with the option to use Alkaline as a backup.

 

[Nebula]

I am in for several if this happens.

 

[apfevervictim]

I'm in too!

 

[Joe Talmadge]

I've been avoiding rechargeables, but I'd take the plunge for this. What would the implications of a lower voltage be? More capacity? Same capacity, but extra room to slip in a protection circuit?

 

[ruralott]

I am in for both AA and AAA

 

[UK Dazzler]

All I can say is that this has been done with the RCR-123A with very little compromise in capacity. If the 14500 3.0v cell still had a capacity of 700-750mah I'd still be up for buying a good few.

 

[gunga]

I think I'd be in for both AAA and AA as well...

 

[Blindasabat]

Interesting, but if only below $8 ea.

...What would the implications of a lower voltage be? More capacity? Same capacity, but extra room to slip in a protection circuit?

Most likely lower capacity to make room for protection/regulation circuit.

And actually, 3.2-3.3V (under light load) would be a better idea. Not much of a difference, but it we are spec'ing voltage, might as well spec the perfect voltage. More Efficiency, less losses, more power.
