The manual says nothing about that. At least, not the manual linked from Noctigon’s M43 page. Perhaps the translator forgot to mention it?

In any case, manuals are great… but test results are better. The manual says it has constant current output… but test results show it does not actually achieve steady output. It’s very sensitive to changes in voltage, even on low modes which should be easy for the driver to handle.
That sounds like a good idea in theory, but it doesn’t seem to actually work. Again, maybe I just got a bad Meteor. But I have the LG high-amp cells recommended on the Meteor’s product page. They’re freshly charged. The light has freshly cleaned contacts. I put them into the M43 and hold the button for maximum turbo. I get about 4800 lm.
Then I take those cells out of the Meteor and place three of them into a D18. I get over 10,000 lumens. 200% as much light from 75% as many cells.
FET drivers are sensitive to many things like cell type, charge state, and contact resistance. But as far as I can tell, the M43 is also sensitive to those things… perhaps even more so. Its highest-power mode is so fickle that I don’t think I’ve ever gotten it to run within 2000 lumens of its spec. It appears to be running in low-power mode even with the exact cells it is designed for.
Maybe I just got a bad Meteor.
If I were more motivated, I’d do like a couple other people have done and replace the driver. It’s a really cute and well-designed host which is enjoyable to use. Hank really did a good job with it. But I haven’t modded it, so it’s still completely stock.
Yes, this is standard low-voltage protection. Almost all lights have this now.
No, there is no point. With a FET, that tests the batteries… not the driver.
If you want to see the shape of the water-cooled turbo discharge curve, look up your cells on HKJ’s battery comparison site. It’s the same curve, and HKJ has all the data meticulously documented.
