Received my Shockli IMR 5500 FLAT top after about 3 or 4 weeks (to arrive in Italy from China).
They were perfectly boxed, with a double battery case and two little magnets to use them in series!
I tried them on my TC20 and worked greatly, now I’m waiting the Acebeam EC50 gen III to be back in stock and try them with it (Acebeam original 26650 battery is not good enough for a 1500 lm or more flashlight…).
P.S. I noticed that they works also in series without magnets :+1:
Thanks Simon 
Where are you order ? Link please.
I ordered directly from Simon, you can write him here on BLF in PM or via customer care of Shockli official page.
It’s the same cell? I’m dying to find any cells in stock that are shipped to germany. (for a normal price)
Very nice review. Thank you.
Ok. I have to say i am very impressed it with the shockli imr… i got the lumen tube, so i get better reading…
Thrunite tc20 with shockli imr
Turn on… 3820 lumen
@30 seconds… 3740 lumen
Thrunite tc20 with thrunite oem 26650
Turn on. 3860 lumen
@30 seconds… 3210 lumen
As you can see shockli imr maintain 3740 lumen after 30 seconds…
Capacity test of the Shockli cell I just got from MTN Electronics. Not sure if it’s the same cell as HKJ tested since the wrapper is different. Discharge current: 500 mA.
Yes it is the same cell, they changed the wrap shortly after it was released.
Idk why, I liked the one with the red warning.
They just changed the wrapper.
Thanks. Yeah, the older label looked more professional, IMO.
Also, the mfg stated max charging current is only 2A, so that’s only about 0.35C. Seems a bit low, given the cell’s low IR and overall capacity. Are there safety concerns about charging it at a higher rate, say 3A?
Or is the 2A rate given to maximize the cell’s life?
Standard charge current from the actual manufacturer, powerlong battery, is 0.5C or 2.75A.
.35C is said to be ideal for longevity, .5C is the “standard” rate, and 1C is a fast rate, for lithium ion batteries in general.
Foul looking chinese market wrapper, in my opinion. “IMR 30A”, incorrect and misleading.
Given that OEMs do not seem completely happy pertaining with direct consumer sales of their cells and we have to live dealing with rewrapping companies, I'd sincerely hope for at least a handful of them to give straight OEM based specifications in their wraps. The rewrapping procedure, as it is, destroys OEM information and alters its specifications. I am not willing to condone this, I fully endorse truth and honesty.
Cheers ^:)
Poor markings, incorrect English translations, and spelling mistakes from a cheap Chinese company? Unheard of. 
Your going to be let down if you expect truth and honesty all the time!
I go by HKJ testing. This is a good battery. I am NOT concerned what the wrapper looks like its what is inside the cell that counts! 
Shockli emailed me this morning[out of the Blue] and are sending me 2 X 18650 3600mAh batteries supposedly the same performance as GA/MJ1,we will see.
Totally looks like it. Send them this PLB INR26650-55A OEM link and ask for product confirmation.
Good luck with Alibaba, tell us how it goes if you do. Purchasing agent maybe?
Cheers :-)
Let’s try to find some difference together? 
“PAC-5500” & “PLB-5500”
Hi, I’m new to the forum but some time I’m following the shockli 5500 post, I recently got a D4S and would like to buy this battery but unfortunately I can not find it. Today I saw an interesting offer of this battery in the site 192led.com and they deliver in Brazil …. anyone can tell me if this site is reliable? I do not want to buy fake product or lose money …. if anyone can help thank you.
