Convoy S2+: the selected group is reset after battery disconnect

I did some testing.

When memory is ON:

- twisting tail switches mode

  • button tap switches mode.

When memory is OFF:

- twisting tail resets flashlight (mode group 1, memory on)

  • button tap switches mode.

Questions:

- how is it possible?

  • can this feature be programmed in different way? E.g button tap switches mode, twisting tail goes to turbo.

Lighted switch?

Nope. Stock S21B with 12 groups 6A driver.

Did the same and mine S21B 6A 12 groups did the reset, but only after I unscrewed the cap fully. Only half turn remembers the settings. Interesting detail - when resetting it also defaults to memory on.

Was the light on or off when you were unscrewing it?

on

Yeap, it’s the same for me - unscrew the cap with the light on and settings are reset. Unscrew with the light OFF - all good.

I have about 6 of these 5A drivers and one 6A driver and they all have this problem. I have talked to Simon about it and if I remember correctly he said he would fix it. I ordered the last 2-3 5A drivers about 3 weeks ago, which was after when I talked to him, and the drivers still have this defect.

I think the drivers are defective and have been discussed on Convoy dedicated thread but AFAIK it hasn’t been fixed. Hadn’t they been cheap and efficient, I wouldn’t have bought them.

Sounds encouraging! Anyhow, the current workaround is robust and not too fiddly. I agree that it’s something I can personally live with. Thanks everyone for their input.

My workaround (if the light resets itself too often, which happens from time to time) is just to stick to the 1st mode group and turn off the memory mode. When I have gone past the mode I wanted, I would just turn off the light, turn on and advance to the mode I wanted.

I’m wondering how it is possible that somehow driver can differentiate between button tap and tail twist. Can it be used for different function like shortcut to turbo on tail twist?

There is just power on and off. It is a mechanical switch, not an e-switch. Turning the tailcap just creates noise that is interpreted as multiple button presses.

I have been waiting for my first S2+ for some time. Last track shows it got to Greenwood IN. But now I learn this model is haunted so close to Halloween, I’m not sure I want it anymore. Imagine trying to escape from a haunt while carrying the thing that is haunted! Can’t be done. Just how is anyone supposed to avoid twisting off the head or tail cap while the light is on?! I don’t know how others use flashlights, but when I carry one, I am constantly and usually unconsciously disassembling all my flashlights while they’re running. How else are they to be used? It is hard to believe such an intolerable defect could have made it to production. This is terrible news.

Sorry, but this is not a defect, it’s physics. Just cut the power cleanly without bouncing when you unscrew the cap and everything will be fine. Look at the signal with a scope, it will show horrible noise.

Do you turn off your computer by pulling the plug as well?

I’m curious as to why one would normally disassemble a flashlight when it’s on, or to turn it off that way rather than using the switch. I’m sure there’s a good reason for doing so but I’m not clear as to what it is.

Thanks

That was sort of my point, but I guess my satire didn’t come across as well as intended.

Well this explains why my 12 group torches reset to the first mode with a pressure switch. Damn it’s annoying.

Now I know to instruct customers to have mode memory on when using the pressure switch, very helpful

Just tested my new Convoy C8+ stock and it looks like it’s been fixed.

Observation:

Old revision with the bug = 10 taps to enter config
New revision = 20 taps

EDIT: Bug hasn’t been fixed :frowning: it only happens when screwing the tail on though. If you unscrew it, click the switch off and then screw it back on, it doesn’t reset.

All that’s required is turning the switch off before untwisting the tail, it’s not normal to take it apart while its on.

The S2+ is an excellent torch to have when you need to escape a haunted mansion or spooky graveyard or maize maze or pumpkin patch. Just make sure to not unscrew any parts of it while it’s on! :smiley:

20 taps seems like a much better design. Getting into configuration mode with just 10 taps is too easy and can cause accidental activation from my experience.
