26650 drawing amps question.

Good morning,

I’m not familiar with 26650s.

Intended application: zoomable
lights in the cars.
Only in emergencies.

I’ve have seen an add for
a Sony 50A. Expensive.

I wish I could find a vaping device
using 26650s.
My highest is 30A in 18650.

Do a need a high A battery to be
used only in emergencies?

Furthermore, do I need a 26650?,
or the 18650s are fine for my intended use.
Siting in the cars for months,
maybe years unattended.

Your kind and informative replies
are always welcome.

Thanking you all in advance,

Carlos.

What do you want to say with 30A or 50A? Are you referring to the current?

Which light do you have in mind which uses so much current?

26650s are for serious ampage output and/or serious runtime. I’d consider them a waste being thrown in a car for months or a year. Plus, I’ve had a good Kong cell completely discharge over the course of sitting for a year and a half.

Your best bet is to get a cheaper 18650 cell (like Trustfire Flames or even “Ultracrap” cheapie cells) and put them in just as cheap lights you don’t care about and stuff them in the glove box. You’ll probably never use them, really. A cheap light with a car charger for emergencies could work, and you never use it enough to worry about safety concerns or performance.

Lithium primary is much better suited to multi-year standby, emergency use.

Hi Werner,

Thank you for your fast reply.

I really don’t know what batteries I need.

It can take 26650, 18650 or 3-AAAs.

Intended use is for the cars (glove compartment)

We usually trade cars every 3 or 4 yrs. Depending on how many miles we use,
Or due to leasing restrictions.

I already own 1 of this flashlights. AMAZING!!!
Way more powerful than my previous Q5s.

I traded my car a few months ago and the Q5
zoomable inside, was in perfect working order,
after 3 yrs in the glove compartment.

Battery voltage (spike maybe) was 4.10V from
an Xtar 2400 mAh. Charged only once.
It was never used though.

Since this light has so much power,
and I will like to have at least 2hrs in high mode,
I’m thinking 26650. I carry 1 spare battery,
but I’m not sure if I can change it in
an emergency.
This light has 5 modes. No memory mode.
The only features I dislike.
I find strobe and SOS unnecesary.

Can I achive this with a high capacity 18650?.

Please, give your input when possible.

All the Best!!!.

Carlos.

I do have lithium AAAs primaries.

Better choice? or ’650s?

Thank you for you kind reply.

I like using CR-123a lights for emergency-kit use. Those primary cells have about a 10-year shelf life so you don't have to worry about self-discharge over time...

It sounds like the XM LEDs won’t really be suitable for flashlight use. Pity…

Little use, so true.

We have never lit a single emergency one.

I do have quite a few UltraCrap, unfortunately.

I think I will run some rudimentary tests,
based on your valued comments.

I’m not too sure about AAAs lithiums though.

Voltage is too high (2.10V) in mine.
They are intended for camera flashes.
But they really don’t last that much
in extended use.

We’ll see.

Thanks again, Carlos.

BTW, I own 3 Keltec handguns and 2 rifles.
That Swedish guy is a genius.
Being at the factory too.
They do everything for free once you’re there.

But I’m off topic yet again.

I have good 123A Energizers
even if they are the Chinese ones.
still @ 3.30V after 3 yrs.

That will be a more plausible solution
than the AAAs lithiums I have, IMO.

The 123As go under 3V under power.
Only the capacity will still be 1350mAh.

Heck, I’ll test them too.

Thank you for your info.
Never crossed my mind.

It’s great when we all get along.

Thank you for your input.

Carlos.

I always forget half of what I want to say.

I’ll be ordering 3 more of this lights to really be able to test the batteries.

Thank you for your pacience.
