The DrJones driver has two main modes. High and med/low Plus ramping. This is the low setting.

Thanks for doing this, I was contemplating this build or rather one similar. Why not 3 18650s in series? Or are you building a triple MTG2?
Yes, you can definitely get 9A or more out of the 18350s. 8)
The mod to make the 7135-based drivers work with the MTG2 can only handle a max of 8.4v input. 3S/12.6v would require a totally different driver setup, O-L and others use these and live with the limitations because the UI is nice and the parts are already at hand.

Awesome!!! I can’t wait to see the finished product!
Looking forward to this ! * gets my cash ready to buy it after *
This is gonna be something different. Not for me at all (MT-G2 does not wow me at all) but it will certainly have something rare and sweet none the less.
I dig it.
I am adding this one to my "must do" builds.
This is going to be ridiculous! Cant wait to see it!
I am using a 6V MT-G2 with NANJG drivers, using the zener mod. I need 2 in series, for the voltage and the 3 sets, (in parallel), of 2 in series, gives me more amperage. 3x18650 in series is just too high a voltage.
EDIT: I coulda just read Post#3 before I made this one.
Even 8 ounces of copper under an MT-G2 at 6.77A is really not enough. 140º on the outside of the head in 5 minutes. And that’s with the copper exposed directly to air, with fins.
9A takes more, lot’s more, not sure if there’s room for enough copper in that light, but it should be fun to play with in bursts.
Updated the OP.
O-L, have you tried Windex (rubbing alcohol works too) on a cotton ball? No scratches. :)
Can’t wait to see the finished product. It should be amazing.
Every time I have used a Cotton ball, it has scratched the reflector. Maybe next time I should not use the ones you pick right off the Cotton plant and use the processed ones instead.
I stopped using Alcohol many, many years ago, but there are still times when feel like I would like to.
I’m clueless, but I sure do appreciate the photos, descriptions, and the time involved in bringing it to the Forum. THANKS!
I always enjoy looking at your process of making copper heatsinks/slugs/inserts. It is always amazing seeing it go from a few pieces of copper pipe to a glorious chunk of heat devouring paraphernalia.
Nice, you made my MT-G2 envy that much stronger…
I sit here after spending a weekend of 40+ degree heat in a lake far away and come back to this. Am I delerious or is OL. What an effort. I’ll have to come back in a couple of days and read this again and make sure that what I just looked at in pictures actually happened.
