I agree and I am prepared. Also have 4 X Aspire 26650 4300 as back up. All brand new cells.
Where is the best place to buy a fresh GOLISI 26650?
Without some kind of high current spacer no one should expect such a high current light to support both sizes. The size difference is just too big to maintain proper contact for both sizes.
Even bypassed springs will work better when there is higher spring pressure on the terminals. All things equal the shorter battery will always be inferior in such a setup. They need to just stop advertising support for both.
Are the Golisi 4300, Aspire 4300 and Shockli 4300 the same cell? According to HKJs graphs the Shockli seems a bit worse than the Golisi in the first 700mah. Are they normal variations in performance or are they different cells?
Edit: Mooch says the iJoy, Aspire and Golisi appear to be the same cell though in HKJs test the iJoy seems to perform a bit worse than the Shockli/Golisi.

No,Shockli 4300 has more of a voltage sag especially at 15A and above.
Golisi and Aspire have been said to be the same cell by the reviewer below.
Not sure - I wouldn't trust those Shockli's though. Yes, definite differences there - look at capacity differences as well - Shockli's test higher. I got a whole bunch of 26650 cells. The iJoy 4200's do pretty good, but less than the Golisi's.
Wow, the Soshine 32650 blows away the Golisi, and the 30T for that matter... Hhhmmm.
Vinh claims his modded K75 to deliver fewer lm, so yes, they are overrated. :down:
Ok - his K75 mod is here: https://skylumen.com/collections/v54-lights/products/acebeam-k75vn-best-ultra-thrower... 5300 lumens max, with a little bump in throw to 1.75 Mcd, if 250 kcd is a little...
Thank you! You are a valued member of BLF, even if you only officially made your account yesterday! Please stick around, friend!
5300lumens! Does a bigger reflector mean more light is lost or is that something I just made up in head?
Is that from a reputable dealer? With a quick search for golisi cell on google, a lot of vape stores pop up. But who knows if they are the real deal cells.
You are welcome. 
They work well for me and the capacities were all just over 4300mAh.
When we do a google search Vape stores are the only ones who sell them other than China.
After doing some calculations… I have come the conclusion that the Golisi/Aspire should be around 20% brighter (over 5A more) than the shockli. Might be more. Who knows? but I don’t like being too optimistic about things like this. Don’t wanna end being disappointed. Oh yh and thanks for the recommendations @BaronVonEissler.
Thanks, I bought two from vapewild. Hope the site is legit. I’m always wary of trying new battery sites. Aliexpress sells this cell too but when it comes to batteries, I don’t buy from Ali unless it is a well known vendor.
I bought my 2 GOLISI's from 3avape back in March - seem good to me. They came in nice black plastic cases. Shipping is up there but usually is.
You are welcome Th558 and SKV89
I bought my Golisi’s from Vape wild and 3Avape. They also came in nice plastic caskets!
I think you will be satisfied with them [as legitimate] from either dealer.
In the UK the best price I can find is £11. I can get two for £18 but I don’t need two.
Just a suggestion depending on how you use the light.
That depends on how much you like Turbo[Max output]. My friends FT03 W/XHP50.2 is 4000 lumens at turn on. He told me it gets 10 to 12 minutes of combined max output w/ a Golisi.I would think this light would drain the battery at least and probably a little more than that with a Golisi or Aspire 26650 4300mAh.
I bought Three batteries for this light. My mistake was that I bought it a few weeks ago without knowing about the group buy on here. :person_facepalming:
