Questions about Parasitic Drain on the SC21 Pro
can someone with proper tools and skills inform
backstory, recent reports on the TS10 show no LVP for button lights, and using High Aux (they are wired as button lights), on that light causes overdischarge.
Thus it will be affected as well, like all Anduril lights with single color aux LED.
thank you,
that is why I am asking what the Parasitic Drain is,
on the Green Button Light on High, of the SC21 Pro.
I want to calculate how many days before Overdischarge.
fwiw, that green button light does not produce a measureable output on my light meter
otoh, the TS10 Red Aux on High, measure 0.2 lumens (and overdischarges within 5 days of 24/7).
fwiw, The Floor output of 1/150 on the main LEDs of the TS10 also measures 0.2 lumens.
Hey Jon,
I measured the parasitic drain on my SC21 pro at 2.5mA on high and 100µA on low.
With an 800mAh battery, that’s roughly 13 days on high or a year on low.
Thank You!
I finally figured out how to reflash Anduril 2 onto the SC21 Pro
the programmer I got from gchart for the SP10 Pro, also works for the SC21 Pro, with a separate harness…
I did not have pogo pins, I soldered the wires to the flashing pads on the driver. The wire harness I used for the SC21 Pro, came from a separate purchase on aliex…
.
all this thanks to Adair21’s post,
plus lots of help from several kind people who coached me privately to install all the software and driver, on my iMac.
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.
