Sofirn SC31 PRO, New Anduril Flashlight

Checked charging voltage on mine.

Charge terminated at 4.2 blinks indicated by the light.
Digital multimeter showed 4.14 volts.

I checked the voltage offset on mine once again. After charging the Sofirn battery in my Nitecore UMS-2 it has a resting voltage of 4.16V. Once inserted into the SC31 Pro it blinked out 4.3V. That’s an offset of at least 0.14V (potentially up to 0.23V).

On TLF some people noticed sharp edges on the heat fins as well as a foggy glas lens. I can confirm both on my sample, too. However, it is not as severe as on some previous models in the past (SC31B, SP33 V2).

I can confirm the Pro is FET+1. It follows the design of the SP36, as they claim they are running the same exact Anduril version as for the SP36.

I pulled the driver. Weak glue holds it in place. 4 wires to the side switch. Used a solder pick to push down on the driver thru the LED+ wire hole, no hammering, just pressure - didn't damage anything. The driver has Chinese lettering on it, based on the SP36 design.

Think mine reads voltage high as well. Sounds like all the differences reported read high.

The charger in the SC31B that I gave away was a little weird too. The light turned green at about 4.something but it continued charging for what seemed like forever. Finally it stopped charging(I was watching it on a USB tester) at about 4.17 volts. It didn’t overcharge but it also didn’t stop when the light turned green either.

Thank you very much Tom!!! :+1: :slight_smile:

Thank you very much Tom :+1:
did you take any picture of the disassembly ?

Just received mine, there are no apparent flaws visible like misaligned charging port or foggy lens. As it uses FET+1 driver, is it safe to run it with 30Q or VTC6 I have laying around?

Which USB tester do people recommend please

Ran mine first few hours on a topped-off 25R (more current that the above), so should be fine there.

Yep, can post this eve.

This is what I have so far:

Thanks Tom E. This is helpful.
Do you have to de-soldier the switch wires to pull the driver out?

I didn't for the pics. Dunno yet - didn't take the switch cover off yet - sometimes you can squeeze the switch board thru the hole. Even if you can't, I've dremel'ed out the hole a bit to make it fit thru on other lights. You could though leave it like I have it to re-program. You can get access to the MCU this way. The FET is somewhat buried behinf the USB-C connector.

The springs don't seem to get fully compressed on a flat top cell, so could probably pick up some power by adding bypasses.

The white stuff is thermal grease, not glue - actually looks like decent quality - moist, right amount applied.

Thanks Tom E, your pictures and your Description in post #150 are really really helpful. I ordered 2 SC31 Pro, i think I can try one for experiment/learning :nerd_face: , I’m interested in Anduril-2 :slight_smile: :smiley:

That’s a really good news!

How many lumens at minimum of ramp?

Just got mine after a hold up in customs. Really impressed. Excellent value and no issues noted. I will order another.

Got mine in 5000K as well. Great value overall, great tint with no green. Sharp fins and sharp lanyard hole, as is tradition. Lanyard hole doesn’t align with anything like it does on my FC11. Also, not happy with the smooth reflector. Thinking of trying to put OP from FC11 or a TIR. All in all, my new EDC with a short tube. Just need that deep carry clip now.

AFAIK, or at least based on the current draft of Anduril 2.0’s documentation, voltage calibration is included: https://bazaar.launchpad.net/~toykeeper/flashlight-firmware/anduril2/view/head:/ToyKeeper/spaghetti-monster/anduril/anduril-manual.txt
