My Edge 530 head unit doesn't report the battery level of my Bryton GARDIA R300L Bike Radar correctly. I get a "battery low" warning when there is 40% battery left (according to the Bryton phone app) and the head unit disconnects from the radar when there is still 30% left. Even at 30% there is sufficient battery for several hours more of riding.
Is there a solution for this?
