Olight i3S how risky is it to use a 10440?

I’ve had my i3S for three days, enjoying it, planning on making it my EDC, but now I am tempted to buy a few 10440 batteries (sorry, cheap ebay ones, 4x for $8 shipped) and give them a try.

With the caveat that use will be strictly hand held and not with nomex gloves, how risky is it to use a 10440?

Anybody that is doing it, does it bump the output on medium setting (default power on setting)?

for $5 more than the crappy batteries, just buy these. Trust me on this, the other cheap batteries are just that, they will have very short run time and will not last near as long. But more importantly, they will not drive your new i3S to it’s full and deserved potential.

To answer your other question concerning retaining medium, Yup it will be there just about twice as bright. Low works too.
But the high is going to blow you away.
High will get hot quick, so best to run it on medium after totally impressing your friends with a few minutes of high :smiley:

Got my Efest’s here and they really ship fast;

+1 I have some cheap Ultrafire and Trustfire 10440s that I bought before I knew the difference... not worth the money at all. Very low capacity, very low output.

Check out HKJ's comparison graph:

how risky??

no risk no fun!!!

Are those Efest batteries protected? So far my AAA lights won’t take protected batteries. I have Tank 007, Fenix LD01, and Thrunite Ti. I also have some ITP A3, but have not tried protected 10440s in them.

No, they are not protected. They are as short as a normal AAA though so they fit in everything.

There is a friendly guy here on BLF that sells efest 10440s among other great stuff. Costs less then ebay even. Support your local BLF seller.

I think his name is RMM. :bigsmile:

RMM $8.49 for 2 shipped. That ebay seller $12.99 for 2.

Just rememmber not to drain them too empty, it will shorten their life… AFAIK pretty fast

Thanks, I ordered a couple to try them. A good price.

Jerm03, if you ordered from RMM check your mailbox.
Some people suspect he hides in the bushes with your batteries just waiting for you to click that order button. :smiley:

Thanks, done.
Jerry

I ordered two from RMM just now, $8.49 shipped, will check mail later.

With a hand held 1xAAA I don’t think protected cells are required, and starting to think I don’t need them in a 1xAA either with a touch of caution.

Caution being, turn off if the light starts going dim or gets hot.

Hard thing with flashlights, deciding between what is fun to play with, and what is practical to use.

About two weeks, only concern is that with the 10440 its so bright I “might” not notice battery voltage dropping until its below 3v. It does get hot fast, so almost zero chance that I would be using it other than a few moments on high, where drop would be most noticeable or in a lower output mode.

Its my EDC and I do walking at night about every other day, mostly using the moonlight mode, but occasionally flipping it up to high or med to look at something or just fooling with the light.

So far not “much” of an itch for my SK68 clone, which has a LOT more light, doesn’t get hot, but takes up a lot more pocket space. Maybe enough light is as good as a big thrower. :wink:

The more lights I buy, the more I learn about what I really want.

I recently received some protected 10440s (black trustfire) that I’ve tried to use in my Olight torches. Neither my i3 or my i3s work with the 10440 batteries - there’s no output at all.

Has anyone else come across this problem?

The 10440s work in every other AAA flashlight I tried - Fenix LD01 & E01, Thrunite Ti, DQG Tiny and foursevens atom a0.

All 10440 are unprotected, some have no nub on the plus side so they don’t make contact. Mine are Efest from the popular forum vendor and work great, but the i3s does get hot within about a minute on high.

Eh, read that as a question, all 10440 are unprotected?

oh wow…look at that drop off…daggum

There does seem to be a couple trustfire, ultrafire 10440s that have a protection PCB. Though _any_fire batteries are pretty junky as WarHawk showed.

Don’t think the i3s is made for 0.8 - 4.2 Volts…
It should not get hot at all.
Also, how do you know you’re under 3 Volts? or even under 2 Volts?
