Who got their LD01 Stainless Steel?

[4sevens]

I think there's more to the story here. The latest info on the other forum shows runtimes with 10440 cell and also it does have low levels. But 4sevens say it doesn't (in the CPFMP post), so which is it?

Low levels do work because of PWM - but still DO NOT USE 10440 cells!!!!!

Wow! This post of 4Sevens is troubling. I bought an LF2X specifically to run on a 10440. I just replaced the 10440 with an Eneloop as soon as I read his post. The liths are sitting on my desk now, and I half-expect them to blow up just sitting there.

4Sevens must know what he's talking about, but then AW (who I bought them from) also has a great reputation here. Can someone tell me why these sorts of batteries are popular if they aren't really safe in flashlights?

Thanks.

10440's won't blow up on your desk - just don't stare at them or they may!!

Li-ion cells are rechargable - they are not the same as lithium primaries made
by energizer which are perfectly safe and are a direct replacement for 1.5v
AAA's.

Honestly lights that are made for only 10440's are just plain dangerous and
the manufacturers who make those lights do not have a concern for consumer
safety. It's dangerous enough with protected li-ions, using unprotected
cells is insane - it's not a matter of IF but of WHEN.

Again - the LD01 works perfectly with normal AAA's. And only normal (alkaline, NiMH, energizer lithiums) should be used.

I just planned on sticking with alkies since they are basically lying in every single drawer at work unused.

We don't even have things that use AAA so I have no idea why our stock people keep delivering them every month. I carried my ZTS mini to work a couple of weeks ago and nearly all of those batteries are at 100%. I tossed the few that weren't.

Now if only I could figure out how to get them to stock CR123's!

Thanks

NiMH rechargeable, energizer E2 lithium non rechargeable.


Although unprotected cells can be dangerous, so can petrol, and yet, you have no problem sitting next to a large amount of it. It's all about how the risk is handled. If you recharge your 10440's frequently, monitor how they're doing, etc, then you'll most likely be fine. If you give them to someone that doesn't know what they're doing, they'll drain them, recharge a few days later, drain them again, recharge a while later, etc. etc. In that case, it's definitely dangerous.



Hmmm. Me and 4sevens seem to have differing POV's. 4sevens, what's your opinion (purely from a safety perspective) of lights such as the draco, drake, lummi raw, lummi wee, etc, and all the other lights I've missed that run on a small, unprotected li-ion?

IMHO these are "hobbyist" lights - meaning most people who buy them know
to run and hide when the light starts to vent and heat up.

You cannot expect that of non-cpf non-hobbyists. For 99% of folks a
flashlight is meant for one thing - provide light and do so in a simple way
without requiring the user to monitor the heat, the voltage or watch for
venting gases.

Sure having an incredible energy density is cool and all. Being able to blow
people away with a tiny AAA light that will blast away anything comparable in
size is just plain fun, but once it leaves your hand - you're going to have to
follow the light around and make sure someone doesn't do something like
leave it on high - which is what 99% of people would do and is expected of
a normal flashlight.

I also make these strong disclaimers because there is corporate liability if
I do not strongly suggest against it. Shame on the vendors who sell the
10440's with the L0D's and LD01's. They are either just irresponsible or
they don't care for the safety of the consumers.

Sorry I just have to say that because it REALLY IS a serious and dangerous
matter. Maybe you all can handle it but no anyone who plays with the light in
your absence (read kids) or take it our of your sight. I just can't stress this
enough. Sorry for ranting.

4sevens, I appreciate that further information. Before reading your last post, I had just called tech support at a flashlight/battery supplier, and he said pretty much what you just did. There are issues with the Li-ion batteries that can be minimized with proper use, such as not over-charging or over-draining. He said the risk then was about the same as being hit by lightening. I wonder if there is any actual data on 'sudden' failure of these batteries? (sudden =)

From what you just posted, it sounds like there might be some prior warning if a battery is about to go bad, such as rapid heating and venting of gases. Maybe enough warning to get the flashlight out of your pocket?

Just don't do it. Thats the best solution.
Honestly, I think there is a less chance of getting hit by lightening UNLESS
perhaps he's refering to hugging trees during an electrical storm :lol:

Just google exploding laptop batteries and you'll find TONS of stuff.
If mac and ibm couldn't prevent bad cells from getting into this laptops
which are very well protected with over and under discharge and current
AND temperature protection (which our protected cells dont' have).

The laptop example is not really about defective cells - it's about what
exactly happens when there is overheating to the point where it catches
fire. At some point, the cells are just fueling themselves. Go search
for videos on exploding li-ion laptop batteries.

Anyway, the point is NOT to discourage people from the LD01. The point is
that you should away from li-ion aaa's which the LD01 was never designed
or claimed to be able to use. 😛

10440 cells are perfectly safe in your liteflux. It is designed to properly secure the cell. 4sevens is advising against the use of a 10440 in the fenix which is not designed for it.

 

[OrlandoLights]

Sorry for taking this thread off-topic, but what you'd said about Li-ion was news to me, and a bit surprising. I will take your advice, and run Eneloops in the LF2X from now on.

Back on-topic, this information negates the advantage I'd seen in the LF2X over the LD01 (ability to use 10440s). And I'd already been looking with some interest at the stainless steel version of the LD01. And I have been very happy with my L1D and L2D.

I think he is advising against the use of Li-ions in general in flashlights.

Aren't cellphone batteries Li-ion? Ka-boom, there goes the side of your head.

Cell phone li-polymers all have protection circuits - except for those
aftermarket ones that skipped them to save cost.

Google exploding cell phones - theres reports of people who've burned off
their ears from using aftermarket batteries!!!

You don't believe me, just do some web searching!

Please re-read my original post about this matter carefully detailed point by point
the real issues. http://www.candlepowerforums.com/vb/showpost.php?p=2706042&postcount=28

Some of these points don't have anything to do with li-ions - for example the flashlight body
mass being too little to dissipate such current to the LED. So 1) your LED will die 2)
you will burn yourself 3) or worse the battery ruptures from overheating.

This point alone doesn't have to do specifically with li-ions and it's already marked "dangerous" in my book.

woohoo the ld01 ss is shipping tomorrow!:twothumbs

Try checking the center of the die and not the dome. The die inside the Cree is off center from the dome. Fenix attempts to center that.

I have a hard time believing that Fenix attempts to center the LED(or the die). NOT ONE SINGLE FENIX that I have has a well centered hotspot. The hotspot is so far off on my T1 that it's annoying. And my L2D is off enough to have a darker area around one side of the hotspot. If they're trying to center them maybe they should hire someone who's not cross-eyed.

And to stay on topic, I have not gotten my Stainless LD01.

I didn't order one. Because the last L0D I got had a nice dark spot in the center of the hotspot at all distances. I'm not gonna take the chance of getting another one like that. I really like the concept of the LD01, but Fenix needs to work a little harder if they want to please the picky flashaholics out there like myself. There are many things I like about Fenix lights, but the last 3 lights I've bought from them have been less than perfect. As hard as it is for me to come up with enough extra money to buy them, I'm not going to "settle" for something sub-par. End of rant.

Our's should ship monday - they're checking each unit in our batch carefully.

If you ever look inside a Fenix, you'll see the ceramic square of the Cree sits inside a well on a pedestal. There's only a few thousands of inch it can move in any direction. On lights I have changed out the emitter, I found sometimes no matter which way you move it, it can't be centered unless one of the ceramic corners are filed.

Nake is right. I just didn't to describe this and seem like I'm blaming cree.
There is not aligning done at all, the cree part has no where to go.
It's the die and dome mounting that has variations

 

[streetmaster]

So basically you just get what you get and that's it. If that's the case, then I don't know why Crees are used at all. Just another reason they should use SSC P4s.

By this you mean that you're hoping Fenix should ship them from China to you on Monday, correct?

How long does it usually take for items to get to you from Fenix?

Thanks!

Yeah. And screw the worse thermal packaging.... :green:
