Convoy 17/22 mm SST40 Driver temperature protection removal

Oops. Sorry, forgot that’s what the thread was about.

I believe this is the 17mm driver:

It’s the bigger one in that circle (at the top of it).

Thank you guys!!
The only thing that was turning me away from this driver was the overaggressive thermal throttling!
Now a way to get a bit for regulated current out of it? SWEET

Thank you!!

Just ordered one driver for my Convoy M2

I have a couple ∅17mm units right here, I can confirm the matching board layout.

Overaggressive throttling? Could you or someone else explain this a little bit better?

We’re near, I’m from Molina de Segura, Murcia :smiley:

In what reviews I spotted of the SST40 based S21A, when you engage Turbo Mode, it almost immediately starts stepping down, pretty much negating anything useful of that mode.

I might do a runtime test of my S11 w SST40 that I’ve taken to 7.2A…

Cant wait, will do mine once resistors arrive.

Already removed NTC.

I left the NTC on…. it gets pretty hot at 7.2……

Also did S2+ M3 M21A M21B.

I’ll risk it, much improvement in output?

300-400lm I think - I’m basing it off this:

My lumen tube isn’t quite ready :frowning:

I gained around 300 lumen with an R050 on the SST40.

The FT03 is still brighter, its driven quite hard

Wow, so bad?

I have to replace the driver in my nephew's S2+, torch predominantly used with the short tube, guess I won't mess with thermal throttling in that one. The other driver, though, is another story.

Hello guys
What about the Convoy M3 driver ?
How can i remove it?

Maybe this thread helps, driver might be sonewhat different though

The M3 has different driver, I’m not sure I find it correctly =((


I think i found it =D

Good info. I just ordered a few of these and I’m sure I will do this mod.

These drivers with the stepped modes look like constant current linear mode FET drivers like led4power’s. Is the other ‘ramping’ driver from convoy mentioned above also this type of driver? The description and UI seem strange. Is the current limited to 8A?

Hi Barkuti & folks,

Can I ask, where is the sense resistor on this board to be sure?

I have ordered the 20mm board 6A version which I supposed is the same as the 17mm/22mm one. Would you be so kind to show me where it is? thanks

Look at your link picture and it clearly shows R010
