Brand new BLF GT90 giving me 2.8V on batt check but all batts are fully charged.

From what I can tell, everything else works properly. I can ramp up/down, lockout, access turbo, moonlight, etc. If I ramp up to about 20% brightness, it will flash three times and then start stepping down to almost a moonlight level. It just seem like the light thinks it’s not getting enough voltage but I’m sure it is…
