4Sevens MINI AA @ ~250Lm!!! with 14500 Battery, Easy MOD!!

[Whisper6911]

4sevens mentions on the website not to run these kinds of cells on your light.

seeing that they do work and it doesn't blow up right away, i suspect the issue is heat sinking.

it seems not to be regulated down to a specific point, and your estimation of 250 lumen is much higher then the 180 that the AA-2 puts out.

i suspect this can kill your light if you leave it on too long.

[Whisper6911]

@Whisper6911 i would suggest the alternative of getting DURACELL CR-V3 packs.

open them up and inside are 2x 3V AA primaries.

3V should be exactly right as the AA-2 runs at 2x 1.5V and i believe it is the same head.

I was going to buy some 14500's until I read on CPF that the lith rechargeables should not be fully discharged and that you should avoid running them below a certain voltage level.

Any truth to that?

If so, Lith rechargeables seem like they would be a pain in the ass unless one has lots of time to waste monitoring them.... I can't worry about stuff like that while hiking or camping for a week or 10 days at a time.

@MARINE1146 Over discharging LiON batteries is not an issue if you buy "protected" cells. they have a built in PCB that automatically shuts the battery off before the voltage drops too low (when you have about 10% power left). go check out the battery selection at LightHound, they tell you which cells are protected and which aren't.

Check out any torch with a Cree led chip, they are un--B--lievabley bright. I just got a 1300lm torch that runs from 1 x 14500 batt. They're cheap as chips on Ebay :)

@Hugo2x

Haha yea no kidding I'm very impressed with the 14500's performance...this my first 14500 light and it is totally worth it..

Thanks for the reply back so fast

[04mach1speed]

Great review

I have a question..

I just got my E03 XML cool tint T6 and my 14500 will be here today so that light cam def handle the huge differance but I guess my question is do u know what the battery runtime on that will be with the 3.7 volt beast?? Cause if it's gunna be like 15-20 min like me Xeno E03 then I wanna buy that 4 sevens and do it :) the worst the battery runtime the better lol that just mean amazing power

Thanks and great review

[hugo2x]

@04mach1speed I love small 14500 lights, they seem to defy physics. Nothing like having a search light with you everywhere you go.

[randy25rhoads]

Have you tried Titanium Innovations' new lithium primary? I think they call it the 14505. ~3.0V, basically a 14500 but not rechargeable. I'd be interested in seeing how they worked in this.

[hugo2x]

@randy25rhoads I haven't tried one but it sounds like it would work

[randy25rhoads]

@hugo2x I actually picked up a Mini AA and some of those Titanium Innovations 14505s. It's one damn fine combination.

[roadkill11091974]

will this work with the Quark Tactical AA?

[hugo2x]

@roadkill11091974 Yes, it will

[busterbob24]

@hugo2x Just to clarify because I was curious about the same thing... this will work in the Quark "regular" (not Mini) series AA models as well?

[hugo2x]

@busterbob24 yes, quark AA regular will accept up to 4.2v, it will therefore accept a 14500 battery.

[marshall3win]

great vid man thanks for posting. helped a lot!

[humanentropy]

is there a AAA version of this battery?

[hugo2x]

@humanentropy yes, its a 10440. I think you can find them on LIGHTHOUND's website

[randy25rhoads]

That would be awesome to have with one of the warm LED versions of that since they're a little dimmer than the normal ones anyway. Great vid.

[tigreslokos]

why do you put carpets on both your hands??

[yoyoguy161]

I see you have some trustfire 14500's on the table. Do they work well with the quark mini or are they too long?

[hugo2x]

@yoyoguy161  the trustfire's are too long

[tybeejeffro]

Uber wicked ! I've got the Preon 2 for my edc. Just ordered the Quark MiNi AA² . Can I run two 14500s in it ?

[hugo2x]

@tybeejeffro I don't think so, but with 2 NIMH batteries you will have very good consistent brightness

[tybeejeffro]

@hugo2x also ordered a Preon I body to go in my Leatherman sheath. Would a 10440 work in the same way?

[hugo2x]

@tybeejeffro Sorry, I don't know. You could do some research on Candlepowerforums.

[MatHahogg]

@tybeejeffro Absolutely NOT.

That would do 8,4 V at the start ( Li-ions does 4,2 V off the charger) and will fry your LED. Don't even try to.

[nutnfancy]

Those 14500 cells are sick and I forgot to mention that in the review...I just linked your video here on it though to clarify. Great job!

[3DFULLHD]

wow i'm impressed

[abusedbunny]

how does the 14500 affect the runtime? is it still 1.3 hours on the new "medium" mode or more or less? also where can i buy a charger and cant find one.

[hugo2x]

@abusedbunny I haven't tested the run time yet but you could probably find one on candle power forums. For a charger go to DealExtreme and search for "12594" Sorry I would give you direct links but youtube won't let me.

[abusedbunny]

@hugo2x

thanks

[davidleon2012]

do they sell those at wallmart

[hugo2x]

@davidleon2012  I wish, that would be so awesome. you can get them on 4sevens website

[matt4270]

The CR2 and CR123 battery versions are 180-190 lumens with the same XR-G led, so I would think it should be fine. I think they dial down the turbo mode to 90 as not too drain a normal AA too quickly.

[hugo2x]

@matt4270 I knew the LED could take the power but my initial concerns were with the driver. I have the mini 123 also, but I like this because I prefer the longer skinner AA to the fatter shorter 123. I'll make a video later to compare the two on output.

[matt4270]

@hugo2x Cool! I have the CR2 and love it. I can get all the Duracell AA's I can eat at work for free, so i'll get a mini AA soon as well.

[gvsfgdf]

They need to come out with a new xre led with high output.... that would make for a sweet thrower... nice review BTW

[gprime22]

never met......well....seen a guy who had a fetish for knives and flashlights.

[hugo2x]

@gprime22 I know tons
