Working for Matt Smith at Lumencraft, I’ve had the chance to test these interesting new lights from Lumintop - and their large new 46950 batteries.

That little spike on the GT is due to reactivating Turbo because I wasn’t sure how it was set - on that light, turbo is 2C from off or on, while on the Mach Turbo is 2C > High > 2C > Turbo… which is annoying.

The lights are very well-built, and I love the form factor. Performance is solid as you can see, output is extremely high. The fan on the Mach V2 works very well and allows for incredible sustained output!
The main reason we did this video was to test the batteries themselves. These are based around the 46mm cells introduced by Tesla for use in their EVs. I tested capacity using my CBA V:
1A Load - 30.216 Ah
5A Load - 28.935 Ah
10A Load - 27.362 Ah
I tested these several times, though had some issues in part due to dirty contacts - though I do wonder if the protection circuit on these cells had some effect, as they completely prevented me from testing with my Xtar chargers.
Results are definitely below advertised spec, however are still very impressive and easily beat 4X 21700s in the same form factor. Considering their massive capacity, these are a really exciting option for future flashlights!
My opinions are more thorough in the video above; in short, these lights are very impressive, and moreso this cell makes me very excited about future lights in this form factor, which offers much improved energy density and high output capability.
My only realy issue with these in particular are the use of proprietary cells, which I am always unhappy to see. Hopefully if this format becomes popular, we will see totally standardized cells in use.
Below are (affiliate) links for these lights, and a couple other similarly-sized options also mentioned in the video:
