Welcome to the forum Yosue!
I have a BLF A6 and several similar size convoy lights (S-series) but I also prefer something smaller for EDC, so I would like to give you another recommendation:
How about DQG Tiny 4th 18650?
I have both the olight S20 and the DQG Tiny1 (older versions of the S2 and DQG 4th)
I like the Olight because it has the magnet in the tailcap, VERY useful for me.
However I like the DQG because it is much smaller and has NW tint. Plus it’s very bright. Got mine on the original pre-order when they first came out back in May 2013, the original is a “twisty” (loosen/tighten the head to operate) It’s very reliable I’ve been using it for 3 years and have not had a single issue with it, I still use it nearly every day. Since the original there has been 3 more upgraded versions, the last 2 went to a side switch.
I’ve been looking at the S2 because its slightly shorter than the S20 (but only by 3mm) and I’ve read the tint is improved (S20 has a very cold bluish/green tint)
But the DQG is much smaller, has the NW tint, and I like the UI: 1 click low, 2 clicks med, 3 clicks high, press and hold for shortcut to Turbo. Plus it’s a great value at the discounted price, so I’ll probably be getting the DQG.

Zebralight sc63
92.5mm x 24.5mm
Brightest of the three (1300lm/CW 1126lm/NW)
Most expensive ($85)
Pros: Brightest, NW available, deeply recessed switch to help prevent accidental pocket turn on
Cons: no knurling on tube, complicated UI may be a con for some, on backorder everywhere
AFAIK none of the above 3 lights would benefit from a high drain battery like the 30q. For longest run time you would be better off with a high capacity battery like this:
3500mAh Sanyo/Panasonic NCR18650GA(protection version)
3500mAh Sanyo/Panasonic NCR18650GA(Unprocted flat top version)
Also consider the astrolux s1 comes with an extra “shorty” 18350 battery tube, so with the smaller battery you can convert it to tiny size when you need to.
The S1 in 18650 configuration requires a high drain battery such as the 30q for maximum brightness, but if you’re not doing the spring bypass mods the 18650GA will give you good balance of output and runtime.
