Because the driver doesn’t use PWM, unlike the 7135s driver, lower modes should still be stabilized if the battery voltage is high enough for that mode even if the higher modes lost regulation.
What’s diameter of reflector and diameter of led triple circle? Will carclo optics do here? What’s depth of driver compartment? Wonder, if H1A driver will fit inside to drive triple in series.
If reflector is deep enough I can design 3D printed gasket-under-glass for carclo 10507, ledil satu, kai optics or even quads.
EDIT: reflector is 28.6mm x 11.1mm (answer from Simon, thank you!)
This means that there’s plenty of space and quad carclo 10622 fill fit. But for singles it’s limited to ~20mm reflectors.
Does anyone know if the S12’s bezel is stainless? Sure feels like it, giving it a bit of a play in my hand. Nice and hefty.
(Want to make sure I have the right info for review 
)
@Simon: while improving inner diameter for 21700 is it possible that you change S21A driver size into 22mm?
Limited by size, the maximum diameter can only be 20mm
yes, it’s stainless steel bezel
Thanks Simon, appreciated. Loving the light
Does new 20700 hosts support pocket clips?
Just FYI:
New Liitokala Lii-50E 5000mAh 21700 battery have 21.3mm diameter and fit perfectly into Convoy S21A.
Just buy the original Samsung cell
Hello!
Anyone tried ordering something from the Convoy store and requesting a discount recently?
AliExpress changed the payment methods, they removed the “other payment methods” option: card, PayPal, WebMoney and wire transfer only now. :|
Messaged Simon in AliExpress, guess this has to be done in some alternative way now. 
Not really. I never asked for any discount.
Yes, just order and do not finish payment
message Simon the ordernumber and mention the BLF Discount and he will give you discount
Does anyone else have problems with M21B tailstanding?
I cannot order without paying this way!
When “other payment methods” was available I would select that, place order and withdraw from the payment page. This is no longer available.
Sorry but fµck1ng AliExpress, this year's site renewal has been a screw-up and it seems not yet done… 
Yes, M21B can’t tailstand, button is juuust a little too big. In fact it can tailstand but on the edge and it’s wiggling.
I think Simon mentioned it will be fixed in next batch, but I’m not sure.
The payments' issue has been reported (had a lenghty chat with customer service). The representative told me the Android application would provide me with the missing “other payments” option. Too bad the app messes up with browser operation, “capturing” website commands and opening up, which I don't like. So I kept the intallation package (apk) and uninstalled it after submitting my order LoL. 
This is a choice of yours because you can afford it, and bear no doubt it provides you with some benefit. I lived with certain abundance years ago, purchasing really good and expensive stuff. Then @#$% happened, or I should better say I chose to learn certain ;-) life lessons. Over the years I've learned to optimize my expenses, now spending only on proper food and following an absolutely abstemious way of life. And much more thanks to mind reprogramming, a true way to healing. And I'm quite happy about it. :-)
I'll eventually live in higher abundance again, I'm somehow attracting it already. ;-)
