I recently picked up a few Godox TT600 manual speed lights, and so far I am pretty impressed. However there is one feature that eludes me, and I am hoping someone else here has experience with these and can show me what I am missing. The official product photos from Godox all show it having a battery level indicator on the screen. Here is one photo, but there are several others on their website that show the same icon. When I read the manual, there it was again. This is identical in the Flashpoint manual, but I assume it's a direct copy and paste from Godox with their own branding added. But on both of my flashes, there is no battery icon, and no menu option to display it. It's just not there. I thought this might just be a fluke, but I came across an Amazon review where someone else noticed the same thing. Is this feature a carry-over from their more expensive Li-ion models that is just not available in the TT600 and got left in the manual and product photos, or am I missing something?
