Looks like I'm most likely going to picking out a driver myself, my host takes 2x18650 and I use Samsung 35E Cells, (3500mah 8A Max Continuous)

Id like to prefer reliability if possible, and softstart would be a big plus.

From my very basic understanding, seems like linear is the most reliable, but I'd like other people's input on this.

And one question also,
1: when turning the pot to desired Current, could you simply break the positive connection from the board to the diode and in-line a multimeter on the conductors going to the laser to set correct current?

Thanks alot ! :)

Yes and no. Nearly all of my diode builds are lab style, and all of them have permanent built in current meters. I have never had any problems driving diodes through a meter. That being said, I always preset the driver to safe specs using a dummy load. Even though the drivers are adjustable, I always configure them so as to be impossible to exceed manufacturer specs for the diode.

Thanks alot! I unfortunately do not have any fancy stuff..... Yet... So I'll try to run it through a meter.

Do you know much about drivers? And what would be a suitable candidate for this diode? Seen alot of superx out there, but I have nada a clue. I'd like to run the diode around 1.9-2A (input 2x18650) to get all I can out of it. Also, I assume not all drivers have softstart?

If you are going to set your own driver, a dummy load is vital. You can build one for less than 5 bucks.
As far as drivers go, wait a couple days for other members to respond. I am sure you will get some good advice.

This is basic idea. You will need larger diodes for 2A, and the number of diodes in the string depends on Vf of your diode.

You can request dtr set your new driver at 2A! So you can solder to your NUGM03 and not nêd tétload, because he has set it for you
