Question about battery type
is the Sofirn 16340 Battery an ICR, IMR, or INR chemistry?
Alright you flashing fiends… while I think the decision on the flashing pad arrangement of the SC21 Pro is just silliness, I just can’t help but make flashing keys (especially when I am persuaded to do so…). I just whipped these guys up, I’ll have them available whenever Oshpark can get them to me (likely a couple of weeks):
Depending on what style of programmer you have, I made two different types of adapters, one with the resistor and diode on board, one without. Really, the one with the resistor and diode would cover both scenarios - you would just connect the RX line and leave the TX empty… but I created and ordered the 3-wire version before I thought about that. Oh well!
3-wire version:
4-wire version:
yay,
Im getting ready to order a couple more SC21 Pro, because, tailmagnet, lighted button, built in charging, great beam, moddable, get the battery too… Makes a perfect Total Package gift for someone new to LiIon…
.
notice the button light stays On when main LED is On…
Hot Tip
if you prefer the button light Off when main LED is On, reflash w gchart’s Awesome TS10 Hex File.
and btw, the SC21 Pro button is Easy to find by touch too, it sticks out nicely. :innocent:
I keep one in my car… can be a hands free car camping/tailgating/tire changing lamp, thanks to the magnet and hatclip, and can also be recharged in the car… w the A to C USB cable included in the package.
And with gchart’s Awesome Hex File and Flashing Kit, it adds Anduril 2, with Firefly lows, and LVP on the button lights. State of the Art!

great work
confused by the choices, I will take whichever Programming kits for both TS10, and SC21 Pro, that you want to sell me. I have a couple TS10 inbound, to fill the gap since this pair went to new homes:
You are an absolute legend! Put me down for a 3-wire version. I’m tired of using my embarrassing homemade key
You got it brother. I’ll hit you up when they come in
Yea, that is pretty ghetto….but effective.
Lol!
Im interested.
Gchart, please put me down for the 4 wire version with diode. That would work great with the UPDI programmer I have.
Thank you, Bob.
Jon, thanks for the link. I just ordered 3 more, one of each color, with battery of course. I see some emitter swaps in my future 
congrats, me too 
here are some recents
I think Im missing one w sw45k :innocent:
If I have these: https://www.amazon.com/dp/B00LZV1G6K, then can I just solder the wire to the jumper connecting TX/RX or is the diode required?
I just got some of those USB adapters. From my tests, I was able to flash firmware just fine. BUT… I have not yet tried that with just jumping the TX and RX together. Some people have gotten it to work, and I think a couple have not reported as much luck.
Those are the adapters I have, I have not tried any flashing yet, I only connected it to my pc to make sure I could see the com port.
No dice. So where is a good place to get assorted diodes and resistors?
Are these still shipping with Anduril 1.0?
yes
the SC21 Pro ships w Anduril 1.
I use gcharts programmer to reflash to Anduril 2.
alternatively, the Wurkkos TS10, and Sofirn SP10 Pro, ship w Anduril 2
Cool, my SP10Pro is on permanent EDC duty, but I just wanted to see the difference in hand between the 16340 and 14500 size lights. Can’t really take the word of people online about feel in hand because, well, their hands aren’t my hands
I might go for one anyway just because they’re so(firn) affordable. Just to see how it feels.
I like the shorter (but fatter) SC21 Pro size better than the SP10 Pro form factor. (both lights have the same carry weight)
.
I also like the lighted button better, the clip rides deeper, and it tailstands better
Very nice - the reflectors are the same size, right? I think I heard that somewhere.
Any luck on finding a TIR that goes in without too much sanding or cutting required? I’ve got DC-Fix on my SP10Pro, but I’m curious if there are any other nice lens options.
