Thanks for the photos.
Your photos showing 3.5V appears to show some blue. It doesn’t look like it is 100% green. My guess is that you will see 100% green when your voltage drops further.
This aux led behavior is briefly mentioned in the first post of the Wurkkos’s TS25 thread.
My battery is at 3.4V and it shows mostly green with slight hint of red. When I look at the aux led with a magnifier, I see red led dimly lit.
I am curious to see if this feature would remain if Anduril handles the aux led.
