BetaFlight Land Now warning on full battery

Betaflight is reporting a “Land Now” warning via OSD when my battery if full (1S HV 550mah). It will do this for the entire flight. If I disconnect the battery mid way through the flight, when the voltage has dropped, the warning message goes away?

Anybody know how to fix this?

My Betaflight power config is below:

Set max cell voltage to 4.5v… For your HV lipos those cells fully charged comes up to 4.5v

Betaflight assumes that because you’re over the max call voltage it’s a 2s battery, and 4.5v 2s is very bad.

That solved my problem.
Thanks guys!
