Well, topic says nearly everything, i need that driver modded to only 1 mode, if possible ofc
I am going to order 30 of those for our security guys here, and they dont like disco or other modes but high
I mailed Bagggood about that matter but i am afraid they wont mod it for me
The driver is probably Nanjg 105c, like this one
If you solder a connection from the + (red) lead to the nearest pin of the adjacent 7135 chip, it will bypass the MCU for a fully regulated single mode. You will lose low voltage warning/cutoff, however.
10x m8, thats an option, didnt knew about it, will offer it to the goys, let them decide, you have been quite helpfull, realy!
See what they did there?
Simply removed the MCU and the voltage divider resistors, and put a 0 ohm resistor across pin 6 and 8, voila single mode wide open as soon as the driver gets power 
Be advised there is NO low voltage protection on that type driver…kinda amazed that the most expensive part of the driver is gone yet it still costs that much…hmmmm
Just thinking that loosing low voltage warning could be a bad idea. Since the torches will be going to people that wouldn’t know when to stop.
True….security guards……they even cant hafl press the button properly and get nervous, rofl P:) Thats why i wanted only 1 mode…but you have a point, i will offer it to the headquarters as an option if they want it so badly , let them decide, i am glad BLF helped me once again,was an issue you know
Then a custom firmware with only a single mode of 255 needs to programmed, thus the driver retains it’s low voltage stepdown/shutoff but only has a single 100% duty cycle on the PWM programmed in.
Someone here could easily whip up a firmware that would only need to be flashed to a standard NANJG driver, flashing it would be a different matter (not that difficult, just time consuming)
RMM (a local forum seller here) could easily build what you are looking for, I also believe Cereal_Killer could do the same, and I appologize to any other modders/sellers I may have forgotten
I really don't think people should be scared or forced to understand the dangers of li-ion, the best thing is to offer the most safety you can.
Mitko - Warhawk is correct. RMM is a good way to go, especially if you want 30. He will not charge you to program the driver but you would not even need that if you solder one of the stars. Read the description and you will see that you can solder the stars for various options.

I would at least select two modes so that you would have a low mode for reading and writing when necessary and of course the high (I would prefer the three mode). These drivers have mode memory so they can select to always start in high mode but have low when they need it.
You say these are Convoys. Which ones? Usually the Convoy have the option to eliminate the flashy modes and make it just three (L/M/H) with mode memory (on-time not off-time)
Well, guys want only 1 mode, their boss too, and its their ultimate demand….i cant do nothing about it
It seems you have never tried to persuade ex military and ex cops…they think they know! We call them “wooden heads” arround here
Anyway, just to make it clear, those 2 have to be shortened?
I already ordered them from Banggood( those 30 pcs), and ofc i have allready problems with the shipping, but thats another topic
Well what batts are you supplying? A good protected cell could be your point if safety. Then just go and solder all the mcu
Yep, if you go that way, you will need to use protected cells, & even then, it’s a bad idea, as they will be drawing current all the way down to ~2.5v (or whatever the protection circuit cuts out at).
You will be relying on a fail-safe only.
The better solution is to re-flash the firmware, & it’s really not that hard or expensive to do.
Yep, just solder a little bond between them, and you’re good to go! (At least, it works like a charm for me 
)
Yeah, i was thinking about that kind of cells too, ofc its the best to reflash the MCU itself, but there is not time for that, it has to be done till 22 of december……and considering the fact that Banggood PROMICED me DHL shipping and they DID shipped them( or at least the site states so) with China post( rofl ) i think that time is pressing us badly
I will wait for the support to come online this evening, trading is always hard with China, they always didnt understand something, no matter what you do
Anyway, back to the point, if i understood correctly, i have to shorten those 2 points on the picture that i posted, right?
I would have just made them two mode lights hi/low.... that always start in high mode.
can't get much simpler than that .
my brother in-law never knew the thrunite ti's were two modes ....drr
The other protection that battery has is that this is not a boost driver, the output will fade before the cell is ruined.
Haha!
Oh yes I have. I even had one of those (ironically one of your fellow countrymen) staying with us for the last 8 months. LOL
I learned that they take orders well then they see the proverbial light :)
In this case here, this same gentleman thought the interest in lights was crazy...that is until he got his hands on one of my Nitecore P12's and my EE F35.
