Great Idea!
Here are some results from me. All measured at the emitter.
Power supply was used. Voltage reading is analog, so it may not be 100% spot on…
My power supply is rated for “4A max at 5V” and “3A at @12V”. That could be an issue. But it did not seem to have issues (cut-off happens it it have issues).
Both 5A drivers are rated to be 100% 50% 5%

I could mention that with an XM-L2 on copper, it was spot on 5A, 2,5A 0,5A when I tested it some time back @ 7,5V. At lower/higher driver circuit input voltage it was slightly off, mostly lower, but also slightly higher than 5A was seen too.

If my power supply did not limit some of these results, then it clearly shows the importance of using 3 batteries if (sustained) high output (3+A) is the goal on an MT-G2. I don’t think my powersupply had issues with the short periods it was used on high with the 5A drivers. My 12V numbers on the IOS 3-18V driver are very similar with MRsDNF measurements with batteries having a resting voltage at 12,2 which would probably be around 11,7 at load. Our numbers match very nicely…
