The There Are No Stupid Questions Thread

Is it reasonably safe to put a protected 18650 (Sanyo NCR18650GA or LG INR18650MJ1) in a cheap USB rechargeable flashlight like the Sofirn SC31 and leave it with the USB charger cable plugged in for extended periods of time (days or weeks)? Or will i actually have to unplug the charger cable when its done charging for safety.

It should be fine. The over-voltage protection circuitry in the battery will keep it from going over 4.2 volts plus the charger itself should stop at the same voltage. The only possible issue might be that after the charger stops working it has a small drain and it could slowly discharge the battery so that after a week your battery may be dead instead of fully charged and you have to charge it all over again. This is why it’s always good to unplug it after it’s done charging.

You can verify that the charger has stopped by using those little USB voltmeter / current meters that you can buy for $5 or $10.

Would an sst-40 go into a blf a6, and would you get any output gains. If so what other mods/ parts are required?
Is there another LED that’d improve output for the blf a6?

It will fit. You need a bigger centering ring for an xml2. I don’t know if it will have higher output. I want to say yes due to its lower forward voltage, but maybe someone else can say for sure.

Thanks I hope someone can help me with a how to on this or another LED more suitable or better for the A6

It already has a top performing led, so I don’t understand.

If there is improvement to be had, why not?
I’d like to look at drivers and more powerful leds too, something nuts…

There is no improvement, it’s already pretty much maxed out. The next step up would probably be to install an xhp70.2 and use a pair of 18350 batteries.

Oh yeah, if you don’t mind a TIR lens you can install a triple or quad led setup.

In some lights the LEDs don’t shut off instantly when I press the switch, but rather dim down until they’re completely dark which takes about 2-3 seconds. Why is this happening?

Probably just a design choice.
It might be better for your eyes to have the light dim down instead of instant off.

I don’t think it’s by design. You can also just cut the power and the LED does the same. Maybe capacitors discharging?

Olight does dimming by design!

And you can also add a capacitor by design against bumps etc.

Can someone please poit me in the direction of getting my Q8 flashed with new UI (NarsilM 1.2 or Anduril). I can’t find a good tutorial on the job.

Thnak you verry much!

Can you remove the driver to mail it to someone?

If so, that will save a lot of money for shipping.

You can try contacting Lexel who is in Germany about reflashing your driver.

You could send the head, but I’m sure it will raise shipping costs.

Thank you for the answer.
I know about Lexel, I already have one made by him.
I would like to try it myself, but I don’t know exactly how and what gear I need and how to go about doing it…

This stuff is too complicated for myself, but I kinda want to learn so I’ve been keeping track of things.

Try this link for parts.

Here are some videos.

Damn JasonWW, when people do give aways they should just stop and give they’re stuff to you instead :laughing:)
Thank you sir, I will look in to it.

JasonWW already answered this and said “… The only possible issue might be that after the charger stops working it has a small drain and it could slowly discharge the battery so that after a week your battery may be dead instead of fully charged and you have to charge it all over again. …”. As far as I'm versed this should not happen because if the battery voltage drops a certain (usually small) amount while the flashlight is still plugged the charging should resume and top out the cell. You could even test this by switching the torch on for a short time while plugged, of course if it works. Best advice try and check it for yourself, no SC31 to test around here. :-)

Cheers ^:)

If you don’t mind me asking, what is this? I’m genuinely curious, is it a frankenstein (’s monster) of sorts?

Here you go.
