Cmon, realy?
Just blob a nice silver solder on the top, the cheapest and the best way to do so: it never fails you know
And yes, Gearbest batteries dont contact properly when in series, the first ones that i bought from Ali do…it seems that we do have a different China revisions of those:)
I am juts hoping that they wont nuke the battery quality some time later
Yep really. 
I had one of those laying around and used it instead of “blobbing some solder”.
Very impressed with these batteries also.
Nice and thank you teacher!! :+1:

That’s odd. I bought two pair from gearbest and both are working fine in series in my L5.
As I have said previously I have 6 cells, 2 from Aliexpress & 4 from Gearbest & they all work in series (which TBH surprised me) in both my S70 & Z1 XHP 50 :+1:
Yeh, a round 4x1mm magnet superglued does it. Center magnet and apply glue ONLY to perimiter of magnet NOT under it. Glue does not conduct.
I have had magnets superglued to flat top pulls for 5 years now and no problems whatsoever.
“Sir headlight”…… all 6 of your LittoKala 26650’s work in series??? I have 4 with 4 more on the way. None of the first 4 work in series at all. :person_facepalming:
I wonder what the differences are??? ( besides the obvious of course )
Hmmmmm… ??
Thanks for the Heads-Up on these Mitko
Ordered yesterday from GB. Showing already shipped via Netherlands Post. I expect receipt in about 6 weeks 
I plan to use them in my L6 that should arrive any day now.
You wont regret those folks, atm they are the best all arrounders and definately batteries that work best with out BLF FET dd drivers
I see now Efest gave birth of a new Purple 4200 battery(at least a new looking one)….ordered several for evaluation
Btw, for my L6/S70 flashlights the best battery that i have tested is Efest 5200 and surprisingly Soshine 5500
No idea what if any difference there is teacher but they definitely all work in both my S70 & Z1 XHP 50 (the only 2 x 26650 lights I have).
To look at the cells you wouldn”t think that they would work in series without a magnet or such like as the tops are very flat & I am surprised myself that they do.
I have had good results too with Soshine 5500 batteries; they will especially work well in a two battery in series set up.
BTW I have the batteries of this thread on order. 
That is certainly interesting. I look forward to seeing if my next 4, that are in transit now; will work in series.
Thanks for the info & ‘consumer report’ bella-headlight………… :+1: …
On the +ve side or -ve? Tradition would say on the +ve to make them feels like “button top” but I see advantages of placing them on the -ve to protect the bottom plate from sharp tail springs of certain flashlights.
So, wait a minute… Are there two versions of this battery? On Ali they are listed as 50A batteries and gearbest states they are 20A. Has this been discussed already? Sorry if so…
I am waiting on these batteries, but from the photographs they look like these would not be a good candidate for using in series. I plan on using mine in my single cell lights.
I am waiting too on the Convoy L6 but plan on using Shockli 4200mAh batteries; they are flat-top batteries with the positive terminal high enough for good contact. Not all flat top batteries can be used in series because of a shallow positive terminal.
Hmmmmm, good eye on spotting that. :+1: I have no idea what the answer is though.
I received 4 from GearBest about a month ago. They are marked like this. ( the black hand writing is mine of course. )
None of my first 4 work in series. I think bella-headlight said all his did. No idea what the difference is besides the obvious.
I have 4 more on the way from GearBest that should be here in a week or so…… maybe.
I’ll see if I can find any difference when they arrive.
PPDB22, the below is what I was told by a reliable source concerning your question.
With regard to the Liitokala 26650“s the 50A rating is pulse discharge & the 20A rating continuous discharge.
Ah. Ok, thanks. That makes sense.
Sure thing, glad to know myself. :+1: …
Oh man! I totally forgot about ordering two from AliExpress and they arrived today.
Since I was no longer aware they were coming I thought Gearbest f#*ked up LOL
They are on the charger now but when done I will compare them to yours Teacher (seems like I’m the only having them from AliExpress)
Hmm 2 heters 6 littokalas 1 On The Road 1 OrcaTorch = 10 (and a poor Ultrafire only used in testing)
Permanent in use 4 (L6/S70)
Nice to have loaded OrcaTorch and On The Road X5, Convoy BD01 and BD06.
I got two too much. Well one for the Z1 instead of high drain Keep power.
OK 1 for another MTG2 or Luminus SST 90 modded Z1. OK I am good, thought a sec I needed a new light
