Anyone know of a charger (4-bay ideally) that fits 26800's?

None exist yet, nor a two cell charger. Your one cell charger is it for now in the solid stuff. Olightworld.com.Olight Flashlights, Tactical Light, Outdoor Light, Weapon Light works well.

This is great - thanks for the help! It really is a pretty great battery. Definitely worth the slight increase in weight compared with using a 21700 in the NSX4 to get that extra capacity!

So far, magnetic chargers appear to be the way to go for charging 26800 batteries (or maybe the built-in charging of flashlights that use 26800 batteries).

Looking around, so far only the single-slot Yonii C2000 26800 battery charger (2A) fits 26800 batteries.

I’ve been looking around for magnetic chargers, and notice these:
Olight UC magnetic charger = this is the only one that accepts both Li-Ion & NiMh batteries

other magnetic chargers only work for Li-Ion batteries:
Folomov A1
Adeaska A10
Trustfire UC10
Nitecore LC10

(and possibly others I haven’t checked)

I’m using the Yonii C2000 and it seems to work perfectly. Pulls 1.6 Amps + according to my USB meter. I’m following the warning that was mentioned in this thread to only use it when it’s beside me And not leave it unattended

Forget the 26800. The 26980 is out and about.
Make sure you buy a charger that charges both.

Try Nitecore UMS4. Can squeeze in two 26800 cells to charge. Otherwise, need to use magnetic cables to charge one by one.

For some time now, but apparently none of the 26980 are all that great in terms of capacity or sag/current. The QB 26800 are pretty damn good.

I’ve been looking in my charger box, and found out that the Xtar SC1 is 800mm exactly.
It needs a little tender loving dremel, but an easy mod. It’s like 5 bucks. And charges almost 2A.
I also have a more expensive solution. The Xtar Over 4 Slim. The battery cavity is 803mm.
Still may need TLD but minimal. It can charge @ 4.1A, 2A and 1A. It charges 2 batteries at the same voltage.
Or you can alternate lower or higher voltage independently. Now your talking money, but also simple.
Texas Shooter cut up the rear in one slot of a Xtar S2, and it does not look too bad.

Thanks to you, I had to order the Alongfire. When I get it, that will be the 30th according to Amazon,
I’ll play with some chargers that I don’t use now. Maybe twenty different models, so it’s a given I’ll find
something to work on. Even if I’ll never use the 26800. I’m into miniatures now. Over 1000 lumens.
Now, for 5 bucks, 4 SC1s and you’ll still be ahead of the cost of the 4 slot chargers.

Cheers.

I would like to find a 26800 charger that works well, isn't too costly, and doesn't require magnets or a Dremel.

I can use a flashlight but, I find that less than ideal personally.

If USM4 can charge 2pcs 26800 at the same time with 2A, don’t even look at anything less than 2A for 6800mAh cells.

Charging a 26800 cell with 6800mAh capacity with 0.5A to 1A, good look being patient with that over and over, it is not even 0.5C charging rate and quickly in time you will feel encumbered using 26800 due to very slow charging rates.

Keep in mind almost all 26xxx type of cells have faster self-discharge rates than 21700 cells so charging will happen more Often than you think to try to squeeze those top lumens, as you don’t want to start with a 4.0V cell 26800 cell.

Just wondering, regarding 26xxx type of cells having faster self-discharge rate = is there a basis/explanation for this behavior, or more from observation?

I haven’t been using 26xxx flashlights much, but a friend of mine who does, also mentioned that 26650 cells seem to self-discharge relatively fast…
Though I haven’t really looked into this, and remembered what he said, as you mentioned the same thing…

I don’t notice any self discharge (to speak of) with any of my 26650 and definitely not with the QB 26800 cells I have. The 26650 are Vapcell red elephants and some Keeppower protected…not sure what cells any of those are exactly. They all settle a slight bit after a charge as any other cell does but they do not show self discharge. The 26800 are less used at this point, around 15-30 cycles each but I’ve been observing them all around since I got them because they were a new unknown cell. They seem excellent. Just pulled out two of the Keeppowers that have been stored in a case fully charged for probably a year and a half and they showed 4.11 and 4.12 volts (those consistently come off the charger at 4.19). I’ve never let the Vapcell sit so long unused but they’ve always been rock solid (probably a couple hundred cycles on those at this point).

I’ve never heard this claim of “faster self-discharge” on particular cell form factors or on 26xxx before. Maybe I just missed that popular opinion/fact? Those cells never get talked about much. If it’s true in some cells I would suspect it’s just the quality/source of the cells, not the form factor. Actually even on lower quality 21700 and 18650 I don’t notice this until they have been very well used…I have noticed it on some cells removed from vacuum and power tool battery packs that led very rough, hot, repetitious lives but that’s to be expected for those types of high drain low capacity cells put to that kind of use.

If your charge rate is limited to something pretty slow, maybe just buy an extra cell or two for rotation so that you’re never stuck waiting on a charge to finish? Nothing wrong with low charge rates on these other than the misery of patience. :slight_smile:

We are developing a new 26800 charger, will release it in the coming months…Please stay tuned!

Post removed to avoid confusion.

Reason: sidetracked.

Still waiting for HKJs review of the Lii-600.

I'm looking forward to it! A better charging solution would be appreciated very much!

Might be a few months old (this thread) but I just saw a clip on youtube

Where this guy says this Nitecore charger fits 26800 cells.
I just ordered one, should get it in a day or two to try out

Oh hey that’s me. That Nitecore UI2 has been serving me well. It’s slow (1A per slot) but the cells fit without forcing or modifying anything.

I wonder if Nitecore botched the descriptions.

U12 lists 26650 as the biggest cell supported.
UM2 has 26700. I can’t imagine 100mm is a big enough difference but my 26800 barely fits (I have to insert it at angle/directly straight).
