Hello, Everyone,
I am happy to tell you that now Shockli 26650,5500mah have button top, good contect in series,please see the below picture.
In addition, i have a question need your help. the diameter of the Shockli 26650,5500mah battery is 26.7mm,a little fat,maybe
can not use for some flashlight. may you share what flashlight can use with this battery ? weclome to discuss.
verry good buttom top
“Factory” button tops may hinder discharge performance (a gnat's ass or so), particularly if made small and connected with a puny nickel weld strip. 
High current deserves wide roads.
Thanks for the update.
While I am sure you are already aware of this, I was asked by Simon to post here to let everyone know that MTN Electronics carries the 3500mAh, 4200mAh, and 5200mAh Shockli 26650 batteries.
We have been dealing with Windyfire/Shockli since early 2015 and they have been very good to deal with so far. We have had a handful of defective items, but they have always replaced them without any issues.
When do you expect the 5500's back in stock? The discharge curves in HKJ's comparator against the LK's looks great!
I’m planning to buy 6 of these 26650s for a special project soon 
Wait - now there's 250 of them in stock, and they are button tops - even better!! Ok I'm good for 4 
250 
This is newlumen again. I ordered 8 of those button top from Richard. Thank you.
I just measured my Maxtoch Mission M12 and Convoy L2 and both of them measured 26.9mm, so the Shockli should be good to go.
@Shockli-Simon do you know of any retailers that sell your 5.500 mAh cells in Germany or support shipping there (like nkon in the Netherlands for example)?
Greatly appreciated, thank you!
Thanks, Richard, we are happy to deal with you. thanks for the members in BLF’s support, we would like to provide good products to you. in addition, i want to correct that MTN Electronics carries the 3500mAh,4200mAh,and 5500mAh Shockli 26650 batteries, not 5200mAh batteries. :laughing:
Thanks for your share, Smittymojo.
Hi, newlumen,thanks for your support of the Shockli battery,wish you satisfied with it. In addition. may you share what models of flashlight can use with Shockli 26650,5500mAh battery?thanks.
welcome to discuss, in order the members can buy the right products.
Hi,Panni,we have retailer in Germany, but he carries Shockli 26650,5000mAh cells, not 5500mAh, you can ask our retailer in UK,his name is Torchythebatteryboy, and see if
he can ship to Germany. thanks.
Hi Shockli,
Any idea how i can buy this in Australia?
Orbtronic could have these at very good (budget) price (flat top), but the diameter 26.60-26.70mm is problematic. So guys what do you think about diameter?
Are these better then the Liitokala 26650-55A? (Not the 26650-50A)
I think those I have at home (not home right now so can’t check) charged to around 5700mAh at 1A nor-test on my LiitoKala Lii-500 charger.
I think it’s rated for 20A continues and 30A pulse.
Checking the aliexpress store reviews where I bought it and the most one reviewer got was 5922mAh on the LiitoKala Lii-500 charger with 1A nor-test but then the charger showed 4.22V…
Can’t give you a link to it… seems weird. I can’t find the product when using the browser but if I search for “26650-55A” on the app and filter on “number of orders” it’s right there on the top with 159 orders right at this point.
The store name is GlobalPower Co., LT Store
Edit: link: https://m.aliexpress.com/s/item/32773040964.html
Needed to put the item in the cart from the app and then go to the browser and check my cart and open the product from there to get the link. Strange…
Depends what “better” means to you.
Assuming the 55A is just a higher capacity version of the 50A, then it will have a larger voltage drop and lower capacity under high load than the Shockly, even though it has a few hundred mAh higher capacity.
You can compare the Shockly to the 50A here: Battery test-review 26650 comparator
Personally I would go with higher discharge voltage and longer runtime under load instead of a few hundred mAh more capacity.
I mean shockli could just have selected the cells from the top notch pile and sent to you.
That why I wrote that 1 reviewer got 5922mAh on the LiitoKala 26650-55A and I got alittle lower.
