Does anyone know if the S2+ clip will fit the S21 correctly?
Most likely not, S21 has a bigger diameter.
Thanks for the point, it’s interesting. I also saw Sofirn SP10S, but this brand usually glues all the head as far as I heard, it isn’t nice. Even omitting upgradeable optics/LED point, what I have to do after breaking the glass, for example?
BTW, single model with optional extension tube (1*AA <-> 2*AA) is even better solution than two different flashlight models, I missed to wish that initially 
I ask because there is a slot on the S21A for one (I think?) and I haven’t seen a specific S21A clip on Simon’s Ali shop listings.
I like 2×AA lights, I’m waiting for a Jaxman M2 at the moment, but I’d be interested in a Convoy S2+ style 2×AA tube light as well
I like long 3×AA lights too, I’d buy several 3×AA tubes for my Convoy S2+ lights and just use the Li-Ion driver :smiling_imp:
not suitable
Same as in biscotti firmware. Only here is the first option.
Config mode
——————
To enter config mode, quickly tap a bunch of times until the light stops lighting up. It should be 16+ times. Then it’ll scroll through the options:
1. Memory toggle. Tap during the “buzz” to turn memory on or off.
2. Thermal calibration. Tap during the “buzz” to enter thermal
calibration mode.
- Light turns on at a low level: Tap now to set default temperature
limit. Otherwise, wait. - Light goes to full brightness: Tap at any time to set temperature
limit to the current temperature. Basically, wait until it feels
hot, then tap.
So, to set a temperature limit:
- Tap 16+ times.
- Wait for the light to blink twice.
- Tap during the “buzz”.
- Wait until the light feels hot, then click to turn it off.
I came here to take a look at the titanium AAA Convoy sample but I don’t see it…

Pics are in OP
Thank you!
I see a twisty keychain…nice.
I don’t like the patina-style anodization but nevertheless I’m very interested.
That 3x SST-20 light looks great!
Will optics fit in that light? I’m curious to see the beam pattern with that reflector.
Does it use a 20mm triple MCPCB? I guess the driver is 22mm and the battery is 21700 (not 21.7 700 lol)
Reverse clicky switch, right?
25mm PCB ,
carclo len doesnt fit .
i have design another host and PCB board for carclo lens ,
driver 22mm,it’s 7135*14 (5320mA) inside.
21.5mm inner diameter ,so some batteries are not suitable ,
i will add links of LG and Tesla 21700 (4800-5000mAH) in my store tomorrow
and it’s reverse switch
uhmmmm,.i tap 16+ times, but dont work……embarrassing…
i will try attiny 25V later
Simon,
Are you going to list flashlight hosts with batteries as well? For the custom modders you know. If you can ship a light with a battery you can probably ship a host with a battery too…
I would definitely buy a few of those combos.
Just for reference, I also remember flashing crescendo in a BLF A6 driver (attiny13) and no matter the clicks, I couldn’t get to the config menu.
At the time I thought that my driver was bad so I flashed back to the original firmware, but now I am starting to see a pattern
AFAIK the Cresendo firmware made for Attiny13A is a slimmed down version of the one made for Attiny25. I don’t think the Attiny13A version has those fancy blinkies, memory and the option to toggle memory on/off.
To be honest, I am currently taking a look at Cresendo’s code and the only notable difference between ATTINY 13 & 25 is the amount of brightness levels that each mcu support.
@Simon Mao, maybe you can experiment with defining a different driver type (NANJG, FET_7135, TRIPLEDOWN) depending the driver you are using.
That AAA Ti light looks fantastic.
Hum, the AAA light looks great Waiting for the AA version as well
