Barkuti .
I just asked for losses.
Nothing else.
I do not know the way you propose and I asked to have a better picture.
I got my black ones a few days ago
Lii500 measured:
5238
5323
5307
5235
Only downside is that they don’t fit in those holders: https://www.aliexpress.com/item/10-Pcs-26650-Lithium-Ion-Cell-Battery-Holder-Bracket-For-Diy-Battery-Pack/32768155893.html because they are bigger in diameter - there might be flashlights where those cells don’t fit.
Aaah, you mean metal spillings, shadockan? None. :-)
I have a couple of LiitoKalas from a dismantled, work in progress powerbank, but it doesn't looks very fine on these as they only have a “dismantled” wire solder. ;-)
I have to solderblob a TrustFire IMR14500 (red-gold) for a friend soon, and he already has one of those done plus an NCR18650B. I'll recall for a nice picture of this to be shot.
Just tested between my blue and black LiitoKala 26650’s in a modified Convoy L6 (FET driver, XHP-70.2)….
Blue showed me 16.48A and did 9,108 in the light box
Black showed me 18.16A and did 9,280.5 in the light box.
192 lumens more at the sacrifice of 1.68A more draw, seems odd, but I’ve seen it where it flips, the one that has highest current doesn’t necessarily produce the most lumens.
I guess that proves the new black one are just as good as the older blue.
Now we need names. We can’t just say liitokala any more. I guess it’s liitokala blue and liitokala black?
Resistor modded L6:
Old: 6.85A
New: 7.28A
Not bad!
Thank you Barkuti.
thanks i was about to ask this exact question. Will order a couple Liitokala 26650 soon for my L6
Amateur, I build with my friend some bike packs.
Welds should be in such a way that there is as little loss as possible.
Nothing special of course, but now I have seen a problem with the BMS and the Volts cut off.
I’m generally looking for the problem ……….
Thank you .
Hi Newlumen
Good weekend .Now shockli 26650 5500mah have button top.it
is good contact for series .
I will keep in mind… I bought 26650 series connector already… in the future, I will purchase that button top.
shadockan, I never said I was into assembling packs profesionally. Doing it with this solder and technique can be relatively fast, yet I believe this is more adequate for custom builds and high current, as I can use and solder very big wires with ease.
I don’t have a solder machine…
How much do the Shockli’s cost?
Shockli flat top cost $8.49 each from the US sellers… about $4 shipping too…
By the way, I am getting worried my 26660/18650 series connector… it has been 26 days since they shipped…
This is an easily fixed problem. 
I’ll just stick with the LiitoKala’s then… much cheaper & real good.
I tried my best to send you some of those connectors so you would have them when you needed them. :person_facepalming:
But no ship to address was I given.
Good day BLFers. Currently I have 2 26650 protected cells for my stock L6. I need 2 more. Can I use non protected 26650 cells? The black Liitokala seems good price, but not protected. Will my stock L6 circuitry can function as protector? Noob question. Thanks :innocent:
Sure you can use unprotected. You’ll actually get a little more output from them due to the lower internal resistance.
If they are flat tops you’ll need to add solder blobs to them.
The stock driver let’s you know when the battery voltage is getting low, but I don’t remember the details of what it does.
