I own Edge 830 and Varia RTL515. In radar description I can find information that battery time is up to 16h in day flash mode (day ride, blinking). But I noticed my radar inform me that I need to charge Varia about every 6 hours. Is it normal? I ride only in daylight, with mode auto what should means blinking mode.
Install and configure yourself the Smart Bike Lights app - apps.garmin.com/.../0d9fd828-c932-4470-9c37-fd2828881888
You can set yourself a full automation of the type of light, for example, depending on…
Do a test and set the "peloton" mode - see how much max time you'll need for the next charge on it.
And one more thing - Garmin used the phrase "Radar, Light Day Flash Mode" for 16h max. …
I called Garmin Support. My Varia will be tested and replaced (I hope!) in Garmin Service. Thanks for help, will inform you if new Varia arrive and will stay blinking about 16h ;)
